    I just purchased a 2001 Tahoe. It has factory Subwoofer & amplifier. My 2nd row door speakers are not functioning. I've been told that it could be a damaged channel on the amplifier. I want to know with the 4 channel receiver how the signal is getting to the 6 speakers. 2 front doors, 2 rear doors & 2 in the rear pillars. Thanks for any information.

    Don't over think it, door speakers get wet and stop working.

    You need to remove door panel and test the speaker(s).

    RayVoy is right...those speakers are notorious for disintegrating. check them first and it is likely you will visually see they need to be replaced.

    I've already pulled off the speakers, they appear fine. I checked the wires and there is no signal going through the wires. That is why I believe that the channel on the amplifier isn't working to the door speakers. Can anyone tell me if the rear pillars are on their own channel? Or do the rear door & pillar speakers work on the same channel?

    I suspect only two channels and front and rear split with fade.

    The doors will have the low and mid-range, the pillars would have the output, frequency split.
