[QUOTE="2ahuman1791, post: 8885917, member: 692658"] I wanted to upgrade my head unit in my 2003 4runner SR5 So I bought a "open box" Kenwood DMX958XR on Crutchfield. before taking my old unit out i made sure it still worked. sound was coming from all 4 speakers. everything good. so i wired up my Kenwood and im only getting mid range sound when radio is on from the rear passenger door speaker. the other 3 speakers are completely silent. very odd. I ended up sending this "open box" unit back thinking it was bruned out. Crutchfield sent me a brand new Kenwood, same model. I hooked it up and same issue. no sound from all those 3 speakers and only odd tone sound coming from rear passenger. I did some research and i rememebr having a old kenwoood excelon in a previous car. in that car the P. Cont wire was hooked up to the red 12v+ ACC switched wire i believe. Or does it plug into 12v constant (yellow)? Ami doing something wrong? I think my P. Cont wire (white/blue wire) is not hooked up correctly. I read that Kenwood uses this P. Cont wire for power to the radios built in amp to produce sound. Am i wrong? does anyone know why im having this sound issue? My old head unit works fine.
