No Rear Sound
When I hook up an aftermarket head unit using a handy adapter harness, I get no sound through the rear speakers. Looking at the wiring diagrams for what should be the rear wires, the adapter seems to have matched those up with the new wires correctly. However, when I fade to rear 100%, I hear nothing. Nothing! Just like Schultz in Hogan's Heroes.
I have a 1995 SR5 model 4R. Are their some tweets under that back panel with some kind of crossover in the middle that the aftermarket head unit doesn't drive correctly?
I've read all the threads about audio I can find and don't see this problem anywhere else.
FWIW, the wiring splices are all soldered and shrinkwrapped.
UPDATE: 5 wires for each rear speaker??!! WTF??? Pulled off rear panel and the connector for the speaker box has 5, count them, 5 wires going into it. What is going on there? Diagrams and such show only 2, the normal + and - wires to drive it. What is going one there my friends?
Thanks for any help!

I had the same problem. In the aftermarket harness they combined the two blue wires. I ended up cutting one and putting it on a switch to the accessory wire. I still have the problem that when i switch from radio to cd, the power ant. will stay up until i flip the switch on and off. The ant. will then go down and my rear speakers work just fine. When I go from cd to radio the ant. goes up like normal and the rear speakers stay on.
