I've got two 4" Polk's in the kick panels, two kenwood 6x9's in the rear cab corners ( I made custom wood boxes to fit in the corners) and one 10" sub powered by a 200x1 amp. I made fiberglass pods for the kick panels (the attached pic). I wish I would have put in 5 1/2's in the kick panels cause the 4's don't have much treble or lows. My dream system would be 6 1/2's all around and two 10" subs behind the seat. I'd have to make new kick pods and modify the rear speaker boxes also. Maybe someday when I move out of my apartment and have a garage
