my question is, what dimensions of a box would u recommend for 2 15 inch volfenhags. the volfs are bigger than normal 15s cuz i put one of them in a single box that originally had a 15 inch kicker and it didnt fit. i had to file the box down. lol. the box will be going in a 96 grand prix. im lookin for SPL and i dont know if i could fit a good ol ported box in my car. but please just give me some recommended dimensions for the box. thanks in advance.
