I thank you both for your input. But what I am asking is, from the harness's female connector behind the radio... Where do the wires trace to when they go out to the doors? Under the dash? Under the carpet? I know the colors... Im just trying to trace them so I can see where my problem is.

Im also thinking maybe there is another connector somewhere.. I even tried and oem radio.. And couldnt hear sound from the left speakers still. So it cant be the aftermarket harness connector.
