I bought a DEH-4600MP from a fellow member and installed it into my 92 Toyota SR5 today. My Toyota had a factory am/fm/cassette Logic deck with factory rear speakers and amps. I installed the CD player with an aftermarket wiring plugin install kit, and the front speakers work fine. The rear speakers will not work now. I double checked my speaker wire connections and they are fine. I have power going back through the gray wire to the rear speakers from the harness under the radio. The factory rear speaker plugin has a white wire with a green tracer that isn't connected to anything in the aftermarket plugin into it, because there isn't any wire in the aftermarket plugin for it. Is it a ground, or what? I need help ASAP so I can get my dash back together/

Thanks,
Doug

 

I got it working!! I used the installdr site and it said to hook the remote amp blue/white wire to the blue wire coming out of the aftermarket plugin for the CD player. Now all my speakers work. It's great to have the truck back together again.

 

Any last words?

Haha, I was gonna try to help ya, but all I could come up with after you saying that is a defective unit!

 

I wish the stereo manufacturers would include a wiring schematic for factory speakers with amps. All I had to do was hook up the blue wire coming out of the main plugin towards the CD player up to the remote amp blue/white wire. After I hooked it up the rear speakers starting working.
