Sub Box and Amp Build Pics
I've been meaning to post these for some time. I've posted the finished product in various threads, but neglected to show some of the progress. I replaced my old sub box which housed 2 JL 10W6 woofers and had installed a single Memphis 15-M3MOJO12 12" woofer capable of handling 2000 watts (1000 continuous). I also relocated my amp from the cargo deck behind the seat to the well with the sub.
My old setup
New woofer
Beginnings of the box with the woofer test fitted.

Re: Sub Box and Amp Build Pics
To finish up, I had a cover made from expanded metal and covered with acoustic carpet to protect the amp and sub from any cargo.

Re: Sub Box and Amp Build Pics
Thanks, yeah I know I don't need the cap, but I got it when I didn't know any better and didn't see a reason to leave it out when relocating the amp. It's almost useless since I use a second battery to power the system.

Re: Sub Box and Amp Build Pics
Okay, you've made me want a big sub. Do you have a file with the plans for cutting the board? Possible dimensions on the sub section? Is the amp sitting on foam, or something?
I've decided that I pretty much want to emulate this setup, minus the cap and the spare battery.

Re: Sub Box and Amp Build Pics
There were no real "plans" for the box, pretty much measure and cut as you go while ensuring the recommended cubic ft volume for the sub. My installer did use as a guideline of sorts, the plans for a well enclosure up in the sticky section of the forum, only he used fiberglass for the bottom half.
This one took him a good week or so to build (thankfully I have another car) along with other jobs at the shop. The size of the sub (it weighs in at 36 lbs!!) and the dimensions of the amp added a degree of difficulty. The plastic trim over the spare tire had to be trimmed off on the bottom to allow wiring to go through. Also a possible mistake in measurement doesn't allow the enclosure to be removed without first removing the pull-down motor (theft deterrent??).
The amp itself is mounted so the top sits flush with the sub surround, then a piece of hardboard (like pegboard without the holes) with the openings cut out was used to create the "flush" mount appearance. No foam, there is a lot of free air space under the hardboard. In effect, the carpet covered hardboard is just a facade to make it look pretty.

Re: Sub Box and Amp Build Pics
Yes I can still access the spare tire, but it's a tight fit with some of the wires. I may take it out entirely and let my roadside assistance coverage take care of any difficulties in that area.

How much did the boxing project run? With the glass work I can imagine a bit more than a normal MDF enclosure.

Re: Sub Box and Amp Build Pics
I can't say how much for sure since I bought the woofer at the same time, then add woofer install, amp install (relocation),etc. Woofer was close to $450 which was almost half of the total price. Best guess is between $350 and $400 for the enclosure.

The baddest bass. Originally designed for SPL competition,
the Mojo sub has more than proven itself in the lanes. Couple it with one of our Mojo amps and you can create enough sound pressure to blow the gasket out of a windshield. If you've got Mojo, everyone will know it.

Re: Sub Box and Amp Build Pics
It's an older Memphis Belle 5 channel amp. Memphis now calls it the Hybrid, it's a Class D amp for the sub channel and a Class AB amp for the other 4 channels.

Re: Sub Box and Amp Build Pics
I believe my installer acquired it from a welding supply shop, where they have various gauges of sheet stock. I wanted to call it perforated metal, but expanded is correct because it's made by cutting slits in the metal, then pulling the metal to "expand" the slits into the diamond shaped holes.

Re: Sub Box and Amp Build Pics
I'm looking at making smaller box to fit a single 12", kind of like yours that isn't flush with the gas tank hump. I see you mentioned this box cannot be removed intact, at least without removing the hatch motor. So how did you get the box in? Did you have to remove the hatch motor to get the box in?
Thanks

Re: Sub Box and Amp Build Pics
If memory serves, the fiberglass was laid in the bottom to get the form, then the framework support was constructed. After assembling the frame and fiberlass, the assembly wouldn't drop into the well without removing the pulldoen motor. I'm sure a few well placed cuts around the motor could remedy the situation, but it works good and I can still remove the trim to access the tail lights.

I had a problem with dual battery banks (starting/house loads) on my boat. I was using an isolator. After killing two sets of batteries from chronic undercharging I rewired the entire boat and put in the ACR. No more problem.

Re: Sub Box and Amp Build Pics
Just a note on isolators. There is a voltage drop across them which can result in undercharging of your batteries. An internally regulated alternator won't be able to detect the state of charge of your batteries. A better alternative to an isolator is an automatic charging relay (ACR) like this one from Blue Sea systems.

This setup has been going strong for about 3 different sound systems I've had in the car over the last 8-10 years.

Re: Sub Box and Amp Build Pics
I can. The cover is acousically transparent, like any speaker grille. Even if it wasn't, it wouldn't matter much with bass frequencies, they'll penetrate almost anything.

Re: Sub Box and Amp Build Pics
so has anyone had any issues with the gas tank or anything when mounting amps or subs on the flat deck area? will sheet metal screws be enough or is there a need for a nut bolt washer type set up

Re: Sub Box and Amp Build Pics
the gas tank is under the hump area not under the well area. if youre mouting anything on top of the hump, be sure to use screws just long enough to go through what youre mounting and just barely through the sheet metal. use long *** screws and you risk putting a screw in the tank...
