Previous owner had a 4 channel sony cd player hooked up to the fader working fine although the volume was low. I want to hook the speakers direct to the sony. I cut the wires and have the 4 pairs that go to the speakers. I used an AA battery to quickly find both front speakers and hooked them up in a few minutes. Then I went to test the rear speakers and can't get a sound from them. I climbed into the trunk to verify the same color wires I was trying to hook up. They were the same. There are 4 other wires that are the same color as the rear speaker wires that went to the fader that have continuity with the wired that should be running to the rear speakers.
I have tried hooking them together, etc.. everything I can think of and I still can't get anything.
Has anyone ran into this problem before? The rear speakers are green striped and red striped with their own negative black wires.
This has really got me stumped.
