The subwoofer speakers are powered from a separate subwoofer amplifier. The ENABLE input circuit, 168 (RD/BK), carries out 2 functions; to turn on the subwoofer amplifier, and to indicate to the audio unit when the subwoofer output distortion signal reaches a damaging level. The audio unit then reduces the audio output signal to the subwoofer amplifier.
