2014 BRZ Limited head unit upgrade help - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

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.

Never mind. I got it figured out. There was some type of audio priority turned on forcing the left side to be louder than the right. Turned it off and everything sounded great.
