    Hi I'm new to a 2009 Tahoe, not sure of the edition yet, and have an issue with the factory audio where the rear speakers don't work. I see many different locations for the factory amp and have checked a few of them, under the console, behind the driver's side dashboard, in the floor but can't seem to locate it. The only 2 places left to check are behind the glovebox or in the rear left panel. Which is the better place to look? I don't want to start pulling off panels if I don't have to. Eventually, I want to replace the factory system, but I can't right now.

    Ok, so I checked behind the glove box and found the XM module but not the amp

    Do you have the BOSE stereo? if you don't have BOSE you may not have an amplifier

    No, it is not the BOSE stereo. If there is no amplifier, then it is probably the speakers themselves. I checked the output at the back of the head unit with an O-scope and there is audio leaving the HU. Guess I'll have to pull a door panel and scope the connections at the speaker.

    I just assumed there was an amp due to the aftermarket dvd headrests that were installed. I figured they did something that broke the connection to the rear speakers.

    Since I can't find an amplifier, and I just get chirping crickets when I ask about it, I'm just going to assume there is no amplifier. I pulled a door panel last night and found that the speaker is dead. Now is as good a time as any to replace the entire system and bypass the non-existent amp. Everything arrives Monday.
