Ok, I found a decent unit I wanted (Kenwood DMX7705S) and purchased a Metra 70-1761 harness and connected everything like it should be to use the existing wiring but the sound quality is awful. It sounds like I'm only getting power to the front two speakers and maybe the doors.
It sounds like the factory AMP isn't connected but I can't seem to find anything online in regards to where that existing connection is or how to properly tap it for this head unit. Can anyone help me out?
The P. CONT wire is what I'm assuming needs to be connected but I have no idea what it needs to be connected to.
