I have a '95 GP and just put in a factory monsoon head unit. I have alpine 6x9's in the deck and am getting ready to replace the door speakers, most likely with infinity reference series. The monsoon was powering a 10(or 8, I can't remember now)speaker setup with power to spare, so I figured I'd make mine at least a 6 and add something like 6 1/2" rounds in the wall panels in the back seat area. Has anyone done anything like this? Thanks
