I am running a 5 channel Alpine PDX-V9. It fits under the driver's seat easily and powers my entire system. It isn't cheap, but it runs clean and cool.

iBlanton Definitely a little late to the party, but I love the tailgate mounted sub. Hated the idea of losing a huge amount of cargo space when installing a sub and this is a great compromise to the problem. Thanks for sharing!

Not yet. I'm considering it, but it doesn't sound bad now.

jayhawkclint Been very pleased with this project. It's received a lot of compliments from friends and coworkers. The finish looks so close to the factory paint that I've had people ask me how I made a speaker box out of metal. The internal volume is around .69 cu ft calculated, taking into account the basket and a piece of damping fill directly behind the magnet. This was just a hair on the low range of the MB Quart's shallow sub mount specs.

If you want to go with a little bit larger internal box volume, it may be worth looking into using a thinner material and reinforcing it with fiberglass. You could easily do this same box with a reinforced 1/2" MDF, maybe even a 3/8" plywood, covered in a couple layers of 'glass. Sand it smooth and paint it and you'd have the same look on the outside.

FWIW, after 6 months riding around in the back of the Jeep, including a couple offroad trips, it has really stood up to some abuse and has almost zero rattle to it. The L-bracket / angle iron turned out to be a great idea for supporting the weight. In addition, I found that removing the plastic vent piece on the tailgate before mounting but leaving the rubber grommet thingies installed plus through-bolting the box behind the spare tire carrier was critical to killing vibration.

Box size

This box is fantastic. I want to have someone do a similar build with a JL 13TW5. Do you happen to know what the volume of the box is? I need 0.8 cu ft and will probably have to have my box guy make it a little deeper.

I've been searching jeep boxes for a while and this is by far the best I've seen.

Got a lot of inspriation from the first post of this thread, particularly from the "L" brackets: https://www.jeepforum.com/forum/f96/s...4/#post5201663

Instead of the "L" brackets, I decided to use a piece of 2" angle iron about 2' long. You can also see the speaker wire I snaked along the pass side in the factory wiring loom:


I built a box out of 3/4" MDF. Originally I wanted to mount the sub off to the left and the amp over to the right, but once I calculated the dimensions I realized that the amp would cut into the sub volume, so I just centered it. The box is pretty much a carcass that has been carved out with a router:


On the back I routed a recess for the wire loom to enter behind the box and also for the angle iron to sit flush:


I was a little worried about an MDF box riding around exposed to the elements in the back of the Jeep, so I shot 3 coats of urethane 2k primer and sanded it all smooth, then shot 2 coats of single stage urethane in the Jeep's grey body color. Should be very weather resistant now:


In an attempt to minimize the rattle, I used some leftover foam-rubber drawer liner from my rollaway toolbox to act as a padding between the box and the tailgate. It's glued on with 3M Super 77:


With the box resting on the angle iron, I removed the spare tire, drilled a couple 1/2" holes and through-bolted the box to the tailgate using fender washers on both sides:


Finished product. Single MB Quart shallow mount 12" subwoofer:

jayhawkclint I put the amp under the passenger seat. I think if the box was built out of 1/2" MDF and used a 10" shallow sub, there would be room to mount the amp in the same enclosure off to the right and the sub off to the left.

That looks great. Where did you install the amp? Is it inside the box?

bear3351 How strong is the speaker. I am worry that anything in the trunk space can hit it and damage the sub.

CHIPMAKER Yeah, it doesn't do much in the dirt, but it gets it done on the black top. Buying a Jeep to replace this...
