(Harold h Pritt jr) Just to see marks face yeah man that’s wasup! Wow when he heard that thing start hitting ! His face lit up like it was Christmas! Love it man great build mark keep bumpin !

(James Poer) I’m

(Billy Buoy) Hey mark! Was wondering since you made a video on this box, could we get the specs for us who have this sub and want to build this box? I know you got a website specifically for box designs. Just wondering since you made this vid if we could get it! I’d be happy to donate some monies to support the next video!

(Ryan Patrick Frisbie) You are the definition of "pro". So impressed with your work and I've learned more from your videos in the last month than all other resources I've accessed over the past 25 years of doing casual installs. Thank you for sharing all your knowledge and experience for us guys that have to do it ourselves because we could never afford to hire someone like you. Appreciate ya'. :)

(Bill McDougall) What is this box tuned to? Also is this the 2 ohm or the 1 ohm?

(Jeremy Ray) Nice build, subbed

(Mark Roberts) Awesome ,beautiful job dude!!

(jameson lewallen) I just bought this sub. I paired it with a rocksford power 1000 amp. Is my amp big enough for this 13” power subwoofer?

(cacahuate conchile) GREAT..

(Car Truck) Nice work man!

(DRM) the threaded inserts are actually placed into the bottom side of the through-holes, then fastened into with bolts through the sub ring holes from the top side, do I see that correctly?

(migas custom sounds) Lol. I got the same table saw.

(No More BS Please) 1:23 Your missing a step. You need to measure the trunk/hatch opening and make sure the box will fit. On an SUV it's not that big a deal, but it's really important in a car. I almost had to rebuild my first tuned box over.

(Vikas SM) Plywood>MDF anyday 😂 Just to avoid the nasty MDF dust during fabrication, If not for anything else!

(Roberto sanchez) I need info about that subwoofer

(ealiev60) what threaded inserts and bolts I should get? Post links please?

(Nino White) 2:02 got me laughing

(Fishhogz) Could get a lot more output with something else for less.. this sub might be one of there more output oriented speakers but it’s still more sq oriented than output.. should make a vid with some sundown zv5’s or some x’s.. if you can afford this you can afford one of those. Have a good one and great content!! Love the box designs.

(Kc Mullins) I wouldn't mind building a box like this for my skar ddx 15 lol

(Kc Mullins) Iv always wondered why Rockford started building od ball sized subs.... Wonder why that is lol.. I'm so used to 12s 15s n 18s.. but 13" 16" n 19" just sounds weird plus the sub cut out is strange and you can't use a standard 12" sub size with it's box anymore unless u build a new front end

(John Carter) Should sell those custom made boxes with CAF signature 👍

(Peter Simpson) Sub foward showing between the captains chairs and port facing back. Ford Expedition. Would that work out?

(Nick Stalhood) So you build an sell custom boxes?

(Tanishq Matharu) well despite you saying that the camera mic was clipping while recording, I am still a bit confused to either invest in a subwoofer or not, I am not a loud bass guy and definitely not a "rattle everything inside the car" guy. Can anyone still tell me is it good enough investment? Currently I am planning to put in some 4 way speakers from Pioneer in my 2011 lancer along with a pair of tweeters. Should I put in an amp anyway despite not using a subwoofer atm? Also, should I go for RF 3 way speakers or pioneer 4 way speakers?

(Dom LS1) I can attest to Crutchfields topnotch customer service. They work with you when you order the wrong thing and need to switch it out.

(Alan Bates) Always remember to wear respiratory protection when milling/routing/sanding MDF in any enclosed space. The binders are carcinogenic.

(Kevin Bein) The dry fitting suggestion is excellent. I have definitely made that mistake before. I made a box for a small SUV that was supposed to perfectly fit in the cargo area with the rear seat up. Then when I installed it I forgot that the tail gate angled inward so even though I though I had undersized it slightly, it ended up being exactly one inch too long to fold the rear seat back up.

(Social P) That looks like it hits really hard 👍🏽

(vivek) 🥰🥰🥰🥰😍😍🤩🤩

(Jazen D) The program you are using to build boxes. Is that yours or is it a program that could be bought and used by someone else?

(CUJO & FRIENDS) That's some high quality work!! Awesome job!! I've gotta get that speaker !!

(Roger Cueto) You have an enclose for the same wrangler that keeps the rear seat? I have a generic box that I'm not too fond of..

(Steelers Luna) I want that sub i have the T1 15

(Jeremywalsh7) Is that audio control lc1500 1 ohm stable?

(joel mtz) which is the freuency response of the box+speaker?

(Jayand Harhangi) Hi Mark, I like watching your videos and trying to build my own ported box with 15" kicker and in their manual the mentioned filling the box with polyfill. I noticed that in all your builds you don't use polyfill, could you explain to us why? Appreciate the work you put in making the videos

(someting is rising but it aint jesuz) this is pathetic. my phone can pump out more bass than that $1300 sub. (jk i love your videos)

(neil singh) Can you build me a box ?

(daniel nino) Hey what box do you recommend for a 1994 Toyota supra ?

(Keanu Venter) Hey Mark could you make a video on a sealed sub woofer box and how to know what volume we should use?

(shivan_ SKB) I have a small question, Does port direction matter? I ask this because when a subwoofer moves the air exiting and entering the port moves 180° out of phase to the subwoofer, can this rob acoustic energy similar to 2 speakers being wired in opposite polarity?

(c.v.r) is there any way that subwoofer orientation matters in ported boxes ? f.e. in this case you are using a topmounted sub and backfiring port. Would there be a noticeable difference if you were to go with driver facing sub and driver facing port?

(Rick Feith) Rockford or JL....who is the king of the high end 13" pigs in your opinion?

(Michael Langerman) That is 1 hell of a box dam.

(scott thompson) That’s awesome!

(Paul Cherry) I'll take that sub off your hands lol

(John Bayliss) Hello dude am looking for a ten inch ported sub box design for a10inch inphase xt sub. Any help greatly appreciated. Dont mind paying for the blu print. Would be made with 18mm mdf

(Joe Pro) Dude I like the channel but u never finish anything. It's always "come back to see me finish this." 🤦

(lightbulb754) Mtx 95 vs Orion hcca. Which is better for sound quality

(BeatAddict303) Nice work, great tutorial, very helpful! Cheers and thanks. (Currently reinforcing and custom fitting an old vintage steamer trunk and could not figure out how to best-contain my sub from the lefts and rights and still have room for a touchscreen on the front, this solved my problem, thanks bud!)

(BigSachsy) Thos guards on that table saw are dope.

(thaddius hill) Where is the video of that subwoofer playing so we can hear the sound quality because I would like to know do that subwoofer play very good because you're not playing it so we can hear or make up our minds to buy that subwoofer so far I am not impressed with that high-dollar subwoofer in that nice box that you build

(Dustin Francis) Hey mark. Where can I get that accordion spacing tool you used to mark for holes?

(Domingo Dominguez Jr) I need a box like this for 2 13 inches. How much would it cost me for the blueprint for this same box but for 2 speakers?

(Ralph Deep) im 58 ...love ac/dc lynard skinard ...you know ....good rock ...so my question is ......WHY THE HELL WOULD I WANT THAT ??????

(TheOriginalBleachX) It's pure crap when people have bass that outplays the mids and highs. Sound is about it all and when the bass drowns out everything else, it's just shit.

(gmodesike) Mark Zuckerberg

(Garret Last) When you have a big dick 3:23

(boogiewithnotahoodie) bro i know i’m hella late but i just watched a 3 min ad for you.. only because it’s christmas. happy holidays

(fasterthanaturtle) Please tell me the name of the tool used to hold the drill bit straight with the through hole for the Allen screw insert. Thank you, Merry Christmas

(benji_328) Is it possible to have a tapered port and still have the box sound good

(Jadrian Canales) that camera's mic gave out so fast

(7munkee) Since when did Mark Zuckerberg start doing audio fabrications on Youtube??

(Travis Boyington) Professional craftsmanship at its finest. 👍

(chad leimgruber) How do you determine your tuning

(Lim的BoRdeR灰界) 说的听不懂，can't believe I to🤔

(Charles Harrison) Tatum at Crutchfield helped me today!

(T C) Crutchfield is legit, great place to deal with.

(clash with todd) Sales gimmicks

(Shivan Harry) Hey mark what you think about 6th order enclosure

(ryan72350) What size is the box?

(Dos koreanitos) Wish I had all those tools. You made art man.

(Dave Eckblad) holy moley I love watching ehse videos. I'm learning way too much way too quickly!

(Daruis441 Bryant) Im new to car audio is razor Power Acoustik amp 1300 watts actually putting out 1300 watts

(H3ntairican) Beautiful sub and that box is beautiful

(fuckyocouchnigga) You are the most informative dude in the car audio game, it's awesome.

(Drew Enero) wow youve got a new sub here..really love and enjoy all the techniques..keep it up..thanks

(Austin Noles) Im looking for a kicker subwoofer i want it to have major bass any recommendations?

(Sheldon Clayborn) Man would love to talk to you some of the crap people post they don't have a clue it's much more than what they think I am a master installer and it just kills me what people say it

(not sure) Well, I guess it's time to buy a router...

(Isaac Fragmatic) In your experience. Which is louder.? The t-line inclosure or the ordinary ported ones?

(crunkwun) Well done lad.. nice build.

(Chrisnas1) Whats the difference between loud sub box and best bass sub box + loud, and what do you recommend me to do from my jL audio 2 w7 12" box from sliding and it not being bolted down?

(Chevy HD) Hi! Perfect video but, Where's the math? The car gave its dimension the box, but how did you get the port tuning? The size of the port? Math detail pls.

(Joshua Herring) Where did you get that layout tool

(Harrison Manyoma) This was an awesome video as you showed how to make sure the sub is perfectly submitted into it's custom box. You're awesome. Thank you for always going over and beyond in what you do. God bless you for what you do.

(Dan Letter) You need to triple the power on that sub. It’s barely moving.

(HENTA AUDIO PATI) Hello Mr.. i have speaker 18"vc5"1800watt. I want to make box speaker for live event or outdoor.. How to count and how to make the speaker box based on the speaker specification...thanks

(MrLilg32) Man I’m looking for software for box design to purchase any suggestions?

(Marcelo Velarde) I hate that subwoofers tests sound like farts...

(DJ Savage) Im looking for prints to make a box for my 2002 BMW e46 convertible. Found a video here on YouTube contacted video host they said they don’t remember how the box was built they don’t have the calculations or schematic so they cannot replicated unless I take my car to them. I live in California they’re in Florida it’s not gonna happen if I send you pictures could you create prints for this box to fit in the trunk of my car?

(Charles Maclelland) Thanks for sharing your passion.

(Sir Douglas Howel, 5th Seat) that CVS giftcard had $2.16 thanks

(jred23pyro) Thanks for the videos bro.. fuxkin sick.

(HARSH DJ DHUMAAL JAMDI) Sara Hindi m bol n

(Glenn B) It would be great if you could do a build video for slim line enclosures

(Liten Fara) In 2006 I went to world famous IFA spells like Int'l Broadcasting Exhibition, where I sat in some US American show cars like Dodge Charger or Humvee with great audio installations. Even some smaller European cars with sophisticated installations were shown. 18" or larger woofers were used, but not put into enclosures instead mounted in organic shaped carbon fiber frames. This way part of the cabins still looked occupied but also half open, so I assume the entire cabin was used as resonance room. My listening experience was overwhelming. I wonder how some people till now give recommendations to build loudspeaker housings into cars these days. Of course one can have a deep bass in the trunk of let's say a Benz SE 560 occupying the entire trunk, but the space is gone and how will GFs respond to that?

(superstick5) If you haven't built a complete sub box and tried to put it into your trunk and it didn't fit I highly recommend. Never in your life will you experience such a feeling.

(Randel Roberts) I don't know if it was my phone or was their a buzz in that sub that's all I could hear

(Andy Kalnins) You made that look so easy, but that is a lot of skill and attention to detail. Very very nice.

(Jose Macon) Do you always design your bracing so it looks like windows?

(Charlie Mitchell) Can u make a video on building a sub box for putting a box behind the seat of a 2017 f350 crew cab for a 12 inch shallow mount sub?

(Eric Ventura) I love the look of that T-Square you used...it looks like it has bearings on it to help it slide? Got a link for it?

(Th3 EcH0) Must be nice to get subwoofers like that for free while others have to pay 1000s for what they have

(Matthew R) Doug recommended your video

(Temple Slug) Rockford needs to come off that price.. If im spending that id rathwr have a W7..

(Up To Bat Entertainment) Awesome box n build vid ✅💪🔥 Imo, that sub needs a RF T-2500 bdcp or something equivalent...

(JC Tejeda) How many hz the tune?

(A Mandal) that's the video I looking for

(Kevin DeGarmo) Any box suggestions for a 2008 mini cooper clubman, 1x15" or 2x12" subs

(Federico Delgado) Design a Chevy avalanche subwoofer box for under the seat for second gen avalanche

(ChevyCobalt Racer) Build my Box. I'll pay lol

(Nissan GT-R) Amplifiers 👎👎👎👎👎

(RUDY MIRANDA) 👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽😎

(Captain Rudy 4021) When the bass is so low that not even the camera can handle it

(250race) Ok what square footage do you need to build a sealed box in an S10 with a cut-through in the Old Skool 12 hx2s? This is a trivia question I had four of those in the bed of my truck the hit 157.4 with two Phoenix Gold 600 titanium series? Just a trivia question that's all all this is equipment was from 2000. In my 2000 S10

(patrick skan) Do you have any speakers you don't mind giving away

(Life Sized) Birch ply first time due to my single 13w7 weighing so much . Does birch resonate?

(Roberto Martinez) Working on the new sound system for my 78 Blazer has been a great experience after watching all your tutorials. Thanks!

(mike hawk) *but all these smart guys say you only need glue and brads. Screws add nothing to strength... I always use screws too...*

(OLDSchool HPL532) I'm trying to build a subwoofer enclosure that hits really hard for my 2017 Subaru Legacy with two JL Audio 12w3v3-4. Is there a subwoofer enclosure design software that you would recommend?

(Sanjay Heaven) do a video on how to find the thiele small parameters if your subwoofer doesn't come with any please

(Joshua Akaka) Mark zuckerberg making speaker boxes...

(Bravo6) How do I find out how much volume 45s take up?

(Dave Something) got that "Chris Fix Hand Model" going on there! =) thanks for the video!

(Kano) my box fit in my trunk... but all the things i carry are less now

(rebelrageracingteam) What's your opinion on adding a protective cover to the front of your Subs I'm always afraid of poking holes in them but I think that might distort the sound as well

(nalinux) You often have a lot of nice tips. I love the spacer at 7:56 ! Now I need to buy some Pop Sicles ...

(Hayder_jz) Youtube_copyright.exe has stopped working 10:15

(Gary Dickerson) Great attention to quality.

(Rui Kazane) I'm glad I'm seeing these again... RF really gets it done!

(@BigTurbo2.0 on IG) Please list the threaded inserts? I'm quit nervous to potentially destroy my custom box trying to figure out how to use them. Can you do a video on training us how to install them several ways, like from the top if box is already built

(Ale Wu) Did you have to upgrade your electrical system for that amp? Was it giving 1500 wats to the sub?

(Lukiepoockie) That sub Is starving for wattage

(Woostty) Beauty box, but Rockford Fosgate..... gross.

(John BassHead & RC Work) VERY NICE ENCLOSURE SIR!

(paveldaddy) Hi Mark. I wanted to ask you something. I glued together a sandwich of 5 sheets in total (HDF, cork, plywood, cork, HDF) around 3/4" thick. I want to build a subwoofer enclosure out of it. What is your opinion on such a mix?

(Жека Валерьевич!) Клёвые станки и инструмент! Есть где разгуляться фантазии в творчестве. Привет звукофилам! ;)

(Fish Pony) Im like an addict to your channel... no food or sleep! Since i found your channel i have just been binge watching lol. Awesome info

(nate0) That motor gets down. I had two custom 12s with ti frames and 4" coils used on those t2 motors. Just wish I had them built properly.

(Robert Kattner) Why do you need a loud subwoofer! Are you deaf! For decades we had woofers, 15" to 24" , up to 36" . Never had a problem hearing or feeling 15 Hz.

(At_The_Speed_Of_Life) is the jeep wrangler a 2 door or the unlimited 4 door? thanks

(TRASH GHOST666) The hardest part is the calculation of the box.

(Csyk) Been doing automotive electronics for a bit, you have a great approach to this field. Very modest but informative. Some people's ego bleeds into their videos, thanks for being courteous and professional.

(Jeffrey Welter) I have a Honda CR-V I have a pair of L7 15s a true JL audio 1000 without having to go underneath the hood and do anything underneath there I would like to put power acoustik two 4000 Watt amps in there internet box towards the ceiling of the car instead of the hatchback of the car what do you think does power acoustik sir strapable

(mptorecon) That sub needs to be on 2 Chainz “Most Expensifive Shit”.

(Jorel Castro) Would there be a way you could help me on this question? Can you use a amp that has rms power of 1125watts at 2 ohms and a max 1500watts at 2 ohms with a subwoofer that has 950 watts rms and 1900 watt max? Btw i have a boss audio pm1500 amp and also wondering if you have any suggestions for that amp?

(amado rosario 1967) horrible

(Damon & Kuldar) Looks hungry

(TheRattleSnake3145) Thank you for not taking 100 episodes to finish the box like other youtubers.

(TJ Ellis) NO NO NO...I will not buy another subwoofer amp again tonight. Where's my wallet?!

(SoulR3ap3r) Car audio is not as big as it use to be and all thanks to the FASCIST PIGS!, There right there to hand you a ticket even when it's not so loud. I had it happen to be several times. They fucking lied about me having it loud and knew it was a lost cause that i would fight being there is a system in my car. WELKUM TO COMMUNIST AMERIKA!. You will not get to enjoy that like we use to be able to, some fascist pig will be lurking around you at the ready to rip money out of your wallet and if your a repeat habitual offender you will have it confiscated!.

(Joshua Woods) Put a 2000 watt amp on that beast!

(1991 2.0si) I'm w u on using mdf. In my experience it does help keep resonance down.

(guillermo correa) I have a 2015 Chrysler 300c what set up would you recommend for it. I'm looking for a better sound then the factory speakers. Would like to change them out ..

(Robert Van Who ?) I need to get and learn to use a router w/table. Then again I need to get a table saw as well. A bunch of bits and accessories. Awww hell lol easier, faster and cheaper to pay someone that has all that.

(Mr. Busy Body) What is the link to the video of you mounting the box in the vehicle?

(Miah Davis) Great video as usual! You should check into getting a set of Grrrippers for your tablesaw work and ditch the pushstick. 😉👍🏻

(stonedbasshead) Crutchfield has excellent cs

(david smith) good job fab kitchen

(Quarnozian) 3:13 But... what if it fits the space perfectly, but it doesn't fit the _opening_ at all? It's a lot easier to get flat pieces into a space and prop them up than it is to get a fully assembled box into the space.

(Brett Lucas) One question I've never gotten a good answer for when assembling an enclosure: Is it better to 1) start from one end of a row of screws or 2) to do the ends, then the middle, then the rest, or 3) middle and work to one ends? Honestly, when building mine it usually depends on the length and number of holes, but I always wondered if there was an objectively optimal way.

(Thinking Impaired) In California most of the people think distortion is normal.

(Mr.009mm Killuminati) Thats all I build my systems for, is the bass. Dont care much for the lyrics, esp in rap songs. But I do love the bass, a true bass head I guess. I always want more thump in the trunk.

(ken cohagen) What saw are you using? I need one, and craftsman still has my trust when it comes to quality.

(Delvin Miller) Whoa! Did Mark from the Fab Kitchen just knock out building a working enclosure in one episode and even included a test bump session? Can't wait to see what friendly fire Doug has on this one! Great looking build so far looking forward to seeing what's in store for the Wrangler 2.0 build.

(Leonie Miano) hey mark! do you have any suggestions on which box building computer program I could download or buy. I'm sick of pen, paper, and math. I would love a good program that will make the design part of my build go smoother and faster...and btw I love your channel thanks for the inspiration!!:)

(Richmond Millier) Finally gets an awesome workshop with the awesome tools that he’s waited ages to be able to have to make these videos.... Makes video with;, ‘... and then, using this old gift card ...’ ha ha I love your resourcefulness.

(Shane Brinkman) I liked the video! But you could of spent a few more minutes showing what the box was tuned at and the position of the box. Placement of the box is very important and will vary in different vehicles.

(Juan C) I want that woofer

(smartassalz) @CarAudioFabrication where can I get that spacing tool you're using in this video? Didn't see it on your tool page link

(Michael itsYAboyMB) That bitch is bad

(David Brown) Meter it please!

(Oliver White) I got a new JLUR wrangler. I’d like to replace the stock Alpine subwoofer. Any ideas on a compatible replacement with and amp that fits in the stock location?

(Stay Tuned) Man I would "kill"for one of those Rockford subs. Not a person but maybe a roach or something I usually kill without feeling bad about it the next day .

(Jeremy Walkden) What flush trim bit is that? Able to cut 3/4” thick in 1 shot is awesome!

(Incorporeal) Has a Q for anyone to answer, can I wire a 3way coaxial and a 2 way component set together in series, and if so, which would be the first inline and do they need to have the same Rms input or would I set the gain to the lowest value?

(Cultivation Plus) Thing was barely even moving. Impressive! I remember my first top firing, port rear facing box. Did a 144.5 with a single DC lvl3 on 700 clamped in my full size Yukon. Very similar box design. Great work!

(Williston Audio Labs) Shaweet box!! I need to build one for my Massive Audio 6kW 12" sub as well.

(Chance Quesnelle) I've never seen you do a demo before lmao it's weird but cool but awesome job man

(Idk Idk) Can I just pay you to build me one ?

(SDS 1) Nice vid

(TOMMY BIG TIME) Nice!!!

(BusyGiraffe) I actually liked this video! I can't want to see what custom stuff you do in this truck and with that box. Did you already sound deaden all other parts of the jeep?

(David Nieves Jr.) Is there a reason why you would put the box in the back seat instead of the storage area? I think I would prefer to lose the cargo space instead of passenger space.

(HahasoNotorious 327) Good job I like it, keep up the good work

(Dieters Hobby PA Kanal) And the Dezibel?

(peter lustig) Reanimation methods of modern days...

(10k Rms) Can build one for my 15 please

(Hector Ortega) Man!, your Shop, Not a Speck of Sawdust or anything, Super Clean!!. 👍

(Gary S) Crutchfield is a great company, they get a lot of kudos ' so do you mark, great work and detailed work, and no cutting corners

(Home2022 Peace) where’s the quality sound! hahahaha!

(Kevin Piper Sr) Great build!!!!Can you please set up a link where I can find those bolts or screws you used to mount this subwoofer...Please!!!

(Caleb Browne) I've been thinking about this very combination.. Audiocontrol 1500/1 in a Rockford 13 and the audiocontrol 1200 6ch... How did the amp work for that Rockford?

(Matt Oneil) Nice work! Anyone know the song title @10:30

(ApexPredator_JKU) Subs up, port back. Is that the ideal enclosure for a vehicle that’s essentially an open air vehicle with the top off? If the owner doesn’t take the top off then it’s not a factor but for someone that does drop the top, what would the ideal enclosure if topless.It’s a big topic of discussion on Jeep forums. Popular consensus is sealed, down fire. Would that be accurate? Any feedback would be appreciated.

(Troy Defond) First ever spl type setup I've seen ya do. Nice to see there's a bass head in there after all. Box is great as usual. Why didn't u use some 9ply-13pky birch instead? It's lighter and stronger? Just curious.

(Barryhandyman) I'm deaf in one ear now from the loud music. Be careful everyone.

(Alex Mayer) I heard that Rafas mom approved

(Alpha Omega) Is that a powerful" sub woofer?

(91rickstar) Wow build and tested In one video not like sound man 5 months later

(Chris Larson) Awesome vid.

(Steven) As always, impressed with your craftsmanship. Please give that subwoofer a second 1500 amp though :)

(Soundman Car Audio) 👌👌👌👌 Looks great dude!

(Adam Moore) Did you use a flush trim bit after you cut all your panels as well? Just to make sure they match?

(Fast Fatty) The cut are sooo clean. Love it

(JOSE A. GARCIA) Great job Mark!!! 👍👍👍 That box build looks great!!! By any chance will you be rapping the entire box with carpet rap or maybe some kind of vineal rap to give it a more custom look to match the interior of the jeep??? Great video can't wait for the next one!!!

(Jon B) I see a lot of comments on how many db. People sometimes it doesn't matter. I respect the bass. I've been an installer at a shop for over 13 years. Sometimes it's about matching the rest of the system. With some planning the car can also sound like a great sounding home theater system. Plus if its a nice car too much bass does do damage. Just my two cents. Great vid and build Mark.

(joe mizer) Do you have a link for that spacing jig thanks

(Dante Boyce) hey mark good vid but wheres the speaker terminal?

(Ryan Kyser) Link to the spacer tool used to line out screw holes?

(9Nails) I've heared that glue holds the box together. Screws work as a clamping force while the glue dries. But how about those inserts? Do they need to be glued in placed?

(TimFPV) Can u build my box for 2 sundown x12 v2?

(MAY03LT) Mark I don't see a link to the awesome spacing tool at 7:56 on yer site.

(pizzamanyoutube watcher ofall) I subscribed last video

(Unconventional Parenting) That's gotta be a super clean sounding system

(SUB ANNIHILATION) Great and very neat subwoofer enclosure Mike. What's the freq?

(Joshua Pullins) That sub is pretty...I rock fi in my ride but, if I was going to buy mainstream it would be a rockford.

(Old men rule racing) Nice!

(Rich Acevedo) here's a tip replace the mic with a kick drum mic youll be able to record the full effect

(Rodrigo César) Top parabéns 👋👋👋

(MrShiffles) Nice build! That Rockford is laughing at that little amp :0)

(Jose Luis Ruiz) Kudos to crutchfield ive bought gear from them many times before and they have always taken good care of me when something goes wrong. I would highly recommend them.

(charlie francis) Crutchfield is awesome, been using them since 1994 👍🏻 absolutely the best audio place to buy a headset , you are an absolute professional, it doesn’t get any better than your builds

(ChrisN85420) when the bass hit for the first time both are mouths hung open at the same time lol

(henrik fors) It wants more POWER!.

(Straight Whitemale) A back up plate made of plywood would have been stronger and would not vibrate apart

(rik whitaker) That was some impressive single sub output.

(Kid Rajah) Should use the SMD distortion detector by @meade916

(Kousin Kielbasa) Nice box build! I'm sure you must have run this through WinISD. What Fb & F3 if you don't me asking? Every time I watch one of your builds, I wish I had a router table and lots of template tape.

(Barrick Stukes) song at 10:30 ????????????

(Arsalan Khan) oh man i wish i had someone like you to install my system.. the love and attention to detail is clearly visible..

(Jr73) I like it!! You do clean installs in the past, now you are running with the big dogs!!

(ecpruthless) That's the first time I think I've seen u actually test bumpin your box. Marc, for your next build...6 15s walled

(Askia Toure) Where is the CAF shop physically located? I need a custom quote

(Toby9103) sweet video man, almost tought i saw a capacitor there but it was fortunately sound deadening :D what tuning did you go for portwise?

(PSE Mentalist) Sweet bass action brother Mark that's badass

(Kevin Hawthorne) Jeezuz Christ, all the boxes I see these days you need a trailer for.

(Richie Khan) Hey do u have any box design for audipipe bd 2 12 inch

(Random Tube) He should sell and ship those perfect built enclosures. Im tired of going to local dealers that don't know how to properly align and assemble enclosures.

(Richard Martin) By adding the window braces, how do you adjust your box calculations for the space those 2 parts are now taking up? and don't you also lose volume by adding the 45° corners? Is there a way to calculate that into the design before you cut the material?

(HifiVega) Beast mode!

(Gintautas Būga) nice job

(Jay) Spectacular build bro. I wrote off Rockford in about 2006 but this sub looks like it is well built. Glad to see them coming back. I was a huge fan in the late 90s. I would suggest using a countersink bit to make recesses for your screw heads. I didn't see it happening here, but MDF can sometimes split when the screw head impacts even when predrilled. I need a link to that spacing tool you use. I've been doing this by hand and, well that's primitive now that I see your tool. Good purchase. Cant wait to see this wrapped up. I like that you're securing the enclosure to the vehicle. I'd love to see some custom head screws holding the sub in!

(toysareforboys) Just FYI, youtube never flags Decaf music on me :)

(Kreepy Pasta) Crutchfield does have amazing customer service.

(arnold Cristi) Podrían poner subtitulos

(Georgi Georgiev) Watching all those videos I am starting to realize that the Chanel should be renamed to "CarAudio Perfection"!

(JayinMI) Where can I find that drill bit guide you used? I could really use that.

(pdbnc) Amazing build quality and attention to detail. Thanks for sharing, this is really inspirational.

(PsychoFish) 10:10 the timing of your bassface is great, because I would rate it 10/10 xD

(Janne Kokko) So Doug, that is how you build an subwoofer box in one episode... @SoundmanCA

(Mennitti) Awesome craftsmanship. I always learn something from you. Great job.

(Joeyd Santos) Which frequency was tuned that enclosure and the size of the box?

(Tommy Grønvold) BOOM!

(Ler Rhann) Okay so I am gonna go Teletubbie here. AGAIN! AGAIN! AGAIN!

(NTZClaw) Awesome bassface! Nice SPL step up. How many DB?

(Daniel Harrell) That 1500.1 isn't even phasing that subwoofer

(Zhu Chai) Make more video recently...dont let your subcribe wait a video for many days and weeks...like your smooth and craft design...wanna see you make custom door design for speaker and carpeting door

(minigamer95) your facial expression alone says it all nice build 😌

(Daniel Harrell) This should be called the caf lab so nice and clean those Diablo blades r nice

(Krazie Ivan) great quality box building, as always. appreciate the screw alignment tips too. but wouldn't the driver position gain free SPL if the box was behind his/her seat, lengthwise, with the sub & port both facing the tailgate? i've been considering trying an 8" t-line in that orientation, ported rear deck to trunk, with other 8s in the doors for punch...'16 Mazda 6 ...thoughts?

(SethH88) It doesnt matter what you did Mark.

(Ramesh Roshiya) You are the best

(denverdan13) So nice...

(DarkLinkAD) Should measure, watts in vs SPL out.

(Dibeezy ThaGifted) The success facial expression is always the best feeling lol. Nice enclosure. That Rockford sub is nice.

(Sp00kMaster) I just bought some new speakers yesterday and the video with the Crutchfield sponsor comes out today. 😭

(Weffy J) Looks great, but can you back up the build with some frequency response numbers? Great video!

(Jia Kabery) So much learning happening. I've been doing this for fun since 1992 and I absolutely love your channel. I just wish I had like 50 cars and millions of dollars to build system after system with everything I learn from your channel. Thanks!

(Augustus Cardoso) Absolutely slapping that royalty free music 😅 Thanks mark!

(Justin Gardner) You used to rough cut with the jigsaw and then trim with the router, why the change?

(Gabe DoubleG Griffin) You make some of the best car audio videos! Makes me want to pick it back up and post more and make videos like you mark! Pretty cool man

(RS94) FIRST :D
