A simple truck style box would have been the way to go. I'd be happy to design one for you...just give me your max bottom depth, height, width, and top depth. You could easily have fit 2-10s (or your single 12'') with a pair of 4'' aeroports firing up or to the side and have your passenger ride as comfortable as you.yes and it came out to a nice fit with the middle seat deal. Its just those things sticking up. I knew the passenger seat was going to be pretty far forward but theres not much you can do about that in a single cab unless you go shallow mount subs
