WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.
The Amplifier has constant fused B+ feed and ground to the module. When an ignition on command is sent over the CAN bus, the Amplifier will wake up and turn on. The Amplifier receives the audio signal circuits from the radio's front right and left, and rear right and left audio inputs and then converts the signals to amplified audio signals to the speakers. The Amplifier monitors the speaker output feeds for any speaker concerns, wiring opens or shorts.
