Normal Operation
The audio unit directs the audio signals to the THX(R) amplifier, which processes the audio signals and sends them to the speakers. Each speaker has a signal and return circuit.

NOTE: The rear tweeters are wired in series with each other. A concern in circuits RME30 (VT/BN), VME30 (GN/BN) or VME47 (BN/VT), or a concern in either speaker, may cause poor/distorted/no sound in both speakers.

DTC B1158 - sets when an open is detected in the RH subwoofer circuit.

DTC B2913 - sets when an open is detected in the LH subwoofer circuit.

DTC B2925 - sets when a short to ground or voltage is detected in the LH subwoofer circuit.

DTC B292A - sets when a short to ground or voltage is detected in the RH subwoofer circuit.

DTC B2965 - sets when an open, short to ground, or short to voltage is detected on any of the speaker circuits.
