I'm down to 2.5 speakers (way back, back pass side, and back driver fades in and out) so I went to Radio Shack and picked up some replacements... I took out the ones in the doors that never worked and put in the Radio Shack ones.. on the passenger side, the copper(?) wire inside one of the connectors doesn't even come close to touching the metal thing on the speaker, and the driver's one looks fine but still no sound... The back ones work without any problems... Any ideas??? 79 K5 Blazer Cheyenne.... That's all I have to say about that.
