i have one for sale. it fits a regular cab and fits really nice, i didn't loose any adjustment out of my seat, just a little tight going all the way back. it has 2 8" subs and sounds great. i listened to hard rock and it fit in well with my mb quart door speakers. there is a slight wear mark on two of the edges. the only thing you have to modify is the plastic jack cover/box. these were 700 new, looking to get 275.00 + the ride. located in mass. thanks, paul c.
