I just bought a panasonic cq-c8803u, and i am getting no sound from the speakers. I even hooked a seprate speaker wire straight from the speaker to the HU and still nothing. Is there any trick on blazer. Its an '89. The HU fires up, just no sound..... Help me please..

 

Ok so I figured somthing out... I cut a pair of speaker wires (green) on the deck harness, and hooked them directly up to one of my speakers... nothing of cousrse, but just by accident the remote (amp) wire touched the green wire and presto SOUND. But this is not normal, what do i have to hook the remote wire up to for it to work right?
