Some vehicles may exhibit low or no sound from some (or all) of the BOSE audio system speakers (i.e. left and right front door speakers, front center speaker and left and right D-pillar speakers).The power amplifier, which controls the output to the speakers may be inoperative due to the occurrence of parasitic resistance in the circuit.
