Hey guys I got a 01 Extended Cab and I was wanting to put in a subwoofer box under the rear seats. Does anyone have any dimensions/pictures of their setup? I know I really need shallow subwoofers so what kind are you guys using? Thanks

 

Check out crutchfield.com, they have what you are looking for. Loaded or unloaded boxes that look like OE equipment.
