Wanting to get a box for my car, it is a honda prelude, I want it to fit inside of the back wheelwells so it doesnt move around alot, width is like 31" and height would be about 14 or 15" can be pretty deep but would like room for an amp rack in front of box. Really want to have it ported also. Am I going to be really limited on a box for them or not? Any info or plans are welcome.
