Normal Operation
The audio unit directs the audio signals to the speakers through separate positive and negative circuits for each of the four audio channels LF, RF, LR, and RR. The audio unit also directs the audio signals to the center imaging amplifier. The signals are then amplified by the center imaging amplifier and sent to both of the center imaging speakers. The audio unit provides internal circuit protection for shorts to ground, shorts to B+ battery or shorts between any output circuits.

Possible Causes
- central junction box (CJB) fuse 18 (20A)
- battery junction box (BJB) fuse 25 (40A)
- speaker(s)
- audio unit
- center imaging amplifier
- speaker circuit(s) open or short to ground
