Many late model Chrysler, Jeep, and RAM vehicles are equipped with an Active Noise Canceling (ANC) module. When adding aftermarket amplifiers in these vehicles, this factory ANC module must be bypassed for proper operation of the aftermarket audio equipment and avoid possible damage to the ANC module. The PAC ANC-CH01 provides a plug-and-play solution for bypassing the ANC module in these vehicles, eliminating the need to cut factory wiring.
