ok so i own a supercrew...duh. and i have a MTX thunderform 4500 i believe in it. its a 10in sub and sub box under my back seat. it sounds amazing...BUT...theres a problem...I cannot fold down my backseat, it only goes 45* down..so when i want to throw my stuff back there i have to be careful and not scratch my leather..so......... i want to design and build a sub box that will go behind my backseats so i can fold them down easily and use the carpet to throw my stuff on..and have some sort of cover for them because I know stuff will be hitting the back with my rapid acceleration. onto the pics and deminsions. heres the space i have to work with. I think i will use the carpet as a template for the box since the floor isnt flat all the way across: its ~57in wide i think the carpet is like 60" and it tucks up under the plastic on the sides a little. with the carpet out and against the back wall to the back of the seats on the floor is 9" and 13.5" tall and 4" wide at the top (where the carpet comes out, not the top of the seats..) so i need yalls advice as to what i need and how to wire it all up. i think i want to throw in 2 12s, one on each side and have the amp in the middle. it will need a grill cover of some sort...I was thinking i could use the factory plastic cover, in which i can use it to hold the grills...and with the seats down theres little flaps that cover the area from the back wall to the back of the seats..make sense?
