See post #2.What about the pioneer system? Where would that be located?
I have the 9 speaker setup, but only the center speaker and the two in the rear deck are pushing anything out. The dash tweeters, the front door speakers, and rear door speakers are completely silent. I checked the amplifier fuse under the hood and it's good. I checked the audio fuse under the dash and it's good. I played with the wires connecting the amplifier (which is in the trunk) and nothing.^ that...theres 2 "modules" attached to the rear passenger fender...
see here
The problem is somewhere starting with the amp all the way to the speakers. The radio is just a standard 4 channel (left/right/front/back). The front center and back subs are derived from that. So, at least one of the 4 door channels has to be working. I'm leaning toward the amp itself. Perhaps the 4 main speakers are all on one chip that's gone bad. But I'd check connectors on the amp. Because that's a lot of speakers to be going bad.I have the 9 speaker setup, but only the center speaker and the two in the rear deck are pushing anything out.

Oh how I miss the days of analog signals.The radio is just a standard 4 channel (left/right/front/back).
I took the amp completely out last night and took it all apart. I was hoping to find a in-house fuse or something. Maybe pregnant resistors. Anything to show a sign of failure. It looked perfect, but that's not say it is perfect. I think you're right about the channels. I'm guessing the front center speaker is the front channel and the subs are the rear channel. And the tweeter, front door and back door are left/right respectively. So, maybe the left and right channels of the amplifier went out?The problem is somewhere starting with the amp all the way to the speakers.

I've struck out at three salvage yards who said they had an amplifier. Each one checked 3 or 4 vehicles and none of them had an amp. I started thinking, forget it, replace the dang thing and wire it myself. Then watching a video this guy said in GM vehicles the door ding is in the front driver door speaker. I figured this was a way to see if my speaker was good. Turns out, the door ding is in my center speaker! What the heck?One little detail - the head unit does communicate with the amp digitally. It controls turning it on/off and maybe something else. If the head unit got swapped with a 6 speaker system, it might cause problems due the wrong software. But that's a long shot.
The head unit only puts out 4 channels. The amp uses those 4 to produce 7 outputs. I think the two subs (rear deck) are derived from the two rear door speaker channels. And the center dash from the two front door speaker signals.I've struck out at three salvage yards who said they had an amplifier. Each one checked 3 or 4 vehicles and none of them had an amp.

Thanks. Do you think the amplifier is the problem? I just bought the car and I'd really like to avoid spending a couple hundred to get all 9 speakers working, lol.The head unit only puts out 4 channels. The amp uses those 4 to produce 7 outputs.

The door chime, being in the LF door, will also be heard in the center dash speaker.
(For anyone counting: to get to 9 speakers from 7 amp channels, the A-pillar tweeters piggy-back off the front door speaker signals.)
Sorry you're having trouble finding another amp. gmpartsdirect.com lists it at $183.

What plano-doug said. The head unit puts the ding in the left front channel. The amp creates the center channel by mixing left and right. But since the left is dead, you hear it on the center.I've struck out at three salvage yards who said they had an amplifier. Each one checked 3 or 4 vehicles and none of them had an amp.
