DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Principles of Operation
The audio unit can be powered up when the key is in the RUN or ACC position. The audio unit provides audio signals to the speakers, thus producing sound.
The audio unit directs the audio signals to the speakers through separate positive and negative circuits for up to 4 audio channels (depending on configuration): LH front, RH front, LH rear and RH rear. The audio unit provides internal circuit protection for shorts to ground, shorts to voltage or shorts between any output circuits.
The radio noise suppression equipment reduces interference transmitted through the speakers by the engine ignition and electrical systems.
