The warning chime tone in your 3001 Chevrolet Monte Carlo comes through the drivers door speaker. That would explain why the radio and the chime fail together. If you are sure the AMP is OK then the fault could be with the radio or the wiring from the radio to the AMP or the AMP to the speakers. If any of the sound output wiring is shorted to ground that would cause the AMP to shut down. If all of the wiring to and from the AMP checks out OK then the fault is most likely the radio or the connections at the radio.
