Adapter, amplifier integration interface for Chrysler, Dodge, Jeep and Ram

If you are installing AmpPRO in a vehicle that is not equipped with a factory amplifier, you must add the amplifier to the vehicle's speakers because the factory radio will no longer have 4-channel variable output after being reconfigured by AmpPRO PRO. For example, this will not work if you add just a subwoofer to a vehicle without an amplifier because the radio will no longer properly power the cabin speakers. Vehicles without an amplifier equipped with an Active Noise Cancellation (ANC) system require a bypass of the ANC module. This can be done manually or with the ANC-CH01 ANC bypass harness (coming soon). Click here to see how to tell the difference between an amplifier and an ANC module, as well as the module locations. The following vehicles have an ANC module that should be bypassed: 2017-2019 Chrysler Pacifica2015-2016 Jeep Grand Cherokee2019 RAM Truck (Non-Classic) Firmware/Revisions https://catalog.pac-audio.com/catalog/amppro-amplifier-interfaces/ap4-ch41-r2
