I’m working on a fun LOUD-FOCUSED build for a Jeep Wrangler, let’s build a custom ported subwoofer enclosure, but what is important for adding extra strength for this HUGE SUBWOOFER?

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'. :)

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

Youll blow the kick drums membrane

[@AnthonyGoodley]

Damn near any mic is better than an on camera mic. Really needs to up his mic game immensely.

[@rickfeith6372]

You'll never EVER be able to get anywhere near the full effect....even if the listening end has a $10k playback system, it's just not gonna come across even remotely close to what it originally was. Certain things are very hard to reproduce sonically...even with a subkick microphone, mind numbing bass like that is lost. The only way to experience that is to be right there.

[@nicewhenearnedrudemostlyel489]

@@rickfeith6372 so my studio recorded albums don't sound the way they did in the studio?

[@rickfeith6372]

@@nicewhenearnedrudemostlyel489 Not entirely....most consumer grade gear has some built in EQ...for whatever reason, from factory tuning, to not flat speakers, to listening position, and a dozen other little things that all add up to a massively different listening environment, take that for what it's worth. This is the philosophy behind studio monitors....they are "supposed to be" extremely flat in their response. That means that from 20hz to 20khz (human hearing) the speakers shouldn't add or subtract more than a couple dB across the board if you measure them. Basically, if you can make something sound good on decent studio monitors in a proper listening environment, it should travel well....that means it should sound even better in your car stereo/hi-fi headphones, home theater, etc. So there you have it....you can pretty much guarantee that whatever you got won't sound entirely like the producer intended, but that's just the nature of the beast....it doesn't mean that it sounds bad, but it will definitely add it's own flavor to the mix.

[@stephendverner]

You should invest in a kick drum mic like a Shure Beta 52a that is design to handle those low frequencies perfectly. Run it through a Zoom recorder and then over sun the better audio into the video in post for the system demos. So far no car audio channel I follow has done this. I know it takes more time but the demos would be more accurate. Not being critical. Just coming from an audio engineer and tech director of 25 years. Might help.

[@CarAudioFabrication]

I have microphones capable of capturing the bass. The problem is 1000 people will watch on their iPhone and then tell me there is no subwoofer bass because they don't understand their iphone doesn't produce that bass.

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.

[@Signatureofheaven]

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.

[@MolonFrikenLabe]

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!

[@ryry7886]

Well if you cant find one you can always use one of those old school jack in the boxes that has a boxing glove that puches you when you turn the handle.

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

[@uncledope77]

If it's a ported enclosure it usually will be substantially bigger. But you have other options & here are 2 options that I like. You can use a sealed enclosure. Which usually requires less air space. But does require more power to be as efficient. As a ported enclosure & also may have less bass than a ported enclosure. But my favorite enclosure is 1 with 2 passive radiators. With a subwoofer in a medium kinda small enclosure. It just depends on the tuning frequency that is desired. To me it's the best of a seal enclosure size. But still having deep bass like a ported enclosure.

[@grantrenfrow9434]

Well it cant be that small he has 8 8 inch subwoofers equaling 64cinches of cone area. So go figure its not a single 12 or 10

[@TimpBizkit]

@@grantrenfrow9434 well wouldn't it be 8 x the square root of 8 unless the 64" subwoofer is only 8" wide.

Have you ever built a subwoofer enclosure from 3/4 birch ply laminated with formica on the internal surfaces/ports? Seems to me that would produce optimal stiffness, reduce weight, and eliminate any concerns about the voids in the plies or roughness of the plywood surface.

[@fishhogz6982]

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.

[@johnalenwork53]

VERY NICE ENCLOSURE SIR!

[@Luciferkrist]

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.

[@mptorecon]

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

[@josea.garcia3994]

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!!!
