Thanks for the reply. Do you happen to know which terminal at the amplifier is the power feed? I seem to have power at most amp terminals but I don't have a wiring diagram to know for sure which is the main power feed. Thanks.

You were absolutely right!!!! Pulled up the rug on the passenger side and the backing was soaked with water. Pulled the harness out of the black plastic conduit and found the orange wire splice corroded. Repaired the splice and all is well again. I've got tunes after 3 months of silence. Many thanks zappaland.

Hey just wondering if there is a way to bypass the amplifier? My Monte Carlo came with a stock amp and has seem to have gone bad and now I don't get any output from my speakers but radio is fine. Before I buy a new amp I was just curious if you found out how to bypass this amp.

The chimes for the car all run through the amp. When you leave the signal engaged for an extended period (forgetig it after a lane change) this also has a chime to it.The buzz could be coming from that.When you turn off the radio and the car, the amp stays engaged to provide the chimes.You could have a bad amp or just to much input for an extended amt. of time.

Our radio locked on our 2002 Impala. The dealership said it was the battery. So, we replaced the battery. Still locked. They said it was the battery cables, maybe. For $400, I wanted a for sure..so they said it was a bad radio. $500. Still locked. Now they say, we will see what next it could be. Anyone else had to pay for their guesses? My husband the electrician has told them it has to be the wires not talking to the computer correctly, or the computer itself at this point. They keep telling us, no, it could be an infinite number of things, we will just keep trying. Any ideas?

I'm no expert but I thought it was a security thing that was VIN dependent and had to be programmed through the vehicles computer when it became locked out. Have you sought out a second opinion from another dealership?

When they replaced the new radio, they reprogramed the computer, and it still locks out the radio. A dealership in another state that we were visiting in, said it was the computer. This is dealership today got all offended, and said there was no way it was the computer.

One type of GM radio theft lock (newer type): Every radio when put in a vehicle is given the VIN number of that vehicle via the vehicle data bus. This information is stored inside the radio's computer. Every time you start the vehicle, the radio expects the VIN info from the vehicle and compare it with its VIN number. If that info is not sent or wrong info is sent, radio will be locked. Any competent dealer should be able to fix this problem. So there may be problem with the vehicle module that sends out VIN info (BCM ? since it controls all other security aspect of the vehicle).
Older theft lock scheme: no VIN data is sent. Owner has to enable this feature and then enter his own security code. And that code is stored locally in radio's computer. As soon as Battery is disconnected from the radio (someone steals the radio and uses it somewhere else), the radio will be locked until the owner enters the correct code. For this type of theft lock, the dealer could also clear it for you for a small fee ($50)
For your 2002 Impala, you could buy an Aftermarket radio and stick in the dash to be done with. This vehicle supplies typical Aftermarket radio with essential signals to make it work (12 V battery, Ignition, Ground, and speaker connections) and forget about the vehicle bus. Circuit City is selling vehicle adapter harness ($15) for all types of vehicle. A decent Japanese radio could be had for less than $200. You probably have to buy antenna adapter too (Circuit City or Radio Shack) since GM radio uses smaller connector vs. typical Motorola type.
