I have entire factory system for sale if anyone wants one. Best thing you can do is take it out. The head unit is marginal, the speakers are paper, the sub-amp (not even subs, mid-bass and paper cones) is weak. The rear sides are 6-1/2 but the grill is for a 4-1/2. The doors half cover the speakers and they're aimed at your feet. The tweeters are on top of the dash and the time phase between them and the lower end (doors) are feet apart. Besides that I'm not impressed. They did leave lots of room to upgrade except for the rear subs depth. Only have 4", I tired Kicker 8" mid-bass, Pioneer 8" shallow subs and finally settled on CDT M6 6-1/2 mid-bass. Did I mention I have entire stock system for sale?
