No..unfortunetly with this setup you loose the ability to recline your seat all the way back. JK Sport (his jeep) and I talked about this in great deal. He is a tall guy and needed max leg room, so his priority was to have the seat be able to go all the way to the rear and wasn't concerned much with being able to recline. The only concern was for his wife on long trips; however, the speaker could have been placed in a flat vertical position that would have allowed the seat to recline. We chose the canted look for astetic reasons. JK Sport, feel free to chime in here..

Looking good Rut! How many layers of chopped mat did you lay on the front where you used the t-shirt material? If it isn't thick enough you will likely have a lot of resonance from the panel. I might have missed a picture or something with that step, so disregard that question if you accounted for that already. If it turns out that you have some resonance once its done anyways, just use some Hush Mat or Dynamat(premium) on the insides of the box, and pack it with polyfill. It helps the tone of a(mostly) fiberglass enclosure a great deal. Amen on the sanding part !! Thats the worst man!! All in all; it is shaping up nicely, keep us posted on how it sounds!

I see, personally I would have added more chopped mat. However in the end you will be fine with all the filler on top. With a 10" and somewhere around 1/2" to 3/4" overall thickness you should be fine no matter what materials you used to make it that way. Its just my preference to use more mat and less filler(did I mention I hate sanding too!). Rut what amplifier are you using? Is it the Alpine 5 channel model that I see guys mounting below the steering column? I cant wait to see this finished; and I hope I don't come across as a know-it-all jack-ass that inst my intent! I just really enjoy my job, and admire those who take on projects such as this; they are fun!

What you can not see in the pics are the supports on the inside of the box. These will also keep the box from flexing. When it's all said and done I think we will be close to 3/8" of an inch. That should be plenty with this setup. Actually I am not sure of the AMP jk Sport will run..I will have to ask him again, or perhaps he can answer if I don't talk with him before then.

Gotcha! I've seen those 5 channels that guys are running in the location under th steering column and I wondered how well that 5th channel is at driving a decent sub. We are not a retailer for Alpine at my shop, so I don't have one handy to test. Keep us posted on how it sounds, please.

The amp is a MTX Jackhammer 600 Mono subwoofer amplifier. It pushes 600W at 2 ohms, which we'll achieve by running the subs in parallel. I had this setup in my Ram prior to rolling it, and it sounded outstanding. Still looking for a suitable location for amp, we have discussed mounting inside the back of passenger seat. Previoulsy had it under the passenger seat, but leaves it accessible for sticky fingers when doors are off. The dimensions of it are roughly 9.25 X 14.75 X 2.5.

Thats a great choice, and plenty strong to run those subs. Like you mentioned it would be a little tricky to install and conceal it at the same time. As creative as you guys are you could always fabricate some sort of stealth pod on the other side of the Jeep(in the same location) to conceal the amplifier and any other electronics you may be installing. The amp would need some space to dissipate heat but that could be achieved with 2 computer fans in an enclosure. Just a thought, and cheers to your build!

Yes, we did..as a matter of fact fleece is the preference for me; however, we are trying to save a little money and had old t-shirts laying around and t-shirts soak up the resin faster. Fleece takes a great deal of resin to be thoroughly soaked.
