I just recently bought a 1999 Grand Prix GT and it still has the factory stereo, which is actually not that bad imo. But for some strange reason, only one of the rear speakers does not work. Since I haven't even owned the car for a week yet, I'm not sure if its dead or not. I checked out the wire harness and everything via the trunk and could not find any clear problems with it. I compared it to the other working speaker and it was all relatively the exact same thing. One of the wires going to the cones of the speaker was hanging off slightly and it didn't look like it was soldered fully to the harness, but wouldn't that mean the speaker never worked? Is there a way I can tell if the speaker is dead or its just the wiring? Tomorrow, I am going to ask my neighbor, who owns an electrical company, for a continuity tester to see if the wires are connected fully without any breaks and to see if the wires are working. But is there any way to tell is the speaker is dead?
