Re: Putting 2 12's through rear deck...
i would just cut out a piece of 3/4" mdf to the same size and shape as the rear deck and nut and bolt it to the rear deck. then go about building the sides. if you can build the box to the correct size and then bolt it up, you da man. you could even get away with actually hanging the box from it and then building supprts or something so not all the weight is in the rear deck. after that maybe some 1/4" hard board on top, to make it flat, and then carpet or whatever.
