If it is a wrangler?? I had one done this way. Take your rear seat out. If you have the money and want it to really hit have a box made in the shape of an L, and use it for the rear seat. Have it covered with vinyl and padding like your original seats and have it mounted to you floor. They can build the box in the Jeep by mounting the bottom and sides together and then in the Jeep. Then they can put the rest of it together. you can build a thin box like a pizza box to mount your amps. with holes of course for venilation. If they can get that out their good and have earned it!! Hope that help out, oh yeah that sh*ts killer for biaaathces to sit on to.
