*How it works:

*This diagram represents AP4 functionality in vehicles with a factory amplifier. Please see compatibility notes about non-amplified vehicles for more detail

• Compatible with both amplified and non-amplified factory systems.
• Jeep Cherokee, Chrysler 200, and Maserati: These vehicles must be equipped with a factory amplifier as the AP4 cannot reprogram the factory radio to think that an amplifier is present.
• When installing into any of the following vehicles, the APH-CH42 is required (sold separately):

Amplified Vehicles

• Compatible with all data-bus controlled amplified systems, no matter the screen size (including the new 12" screen). To identify these systems, look for logos on door speakers, tweeters, dash speakers or the subwoofer to confirm if the vehicle has a compatible amplified system: Alpine, Beats or Harman Kardon. Some vehicles may not always have branded compatible systems. Unbranded amplified systems are generally identified by locating a center channel speaker or subwoofer.

Non-Amplified Vehicles

• Jeep Wrangler/Gladiator: Compatible with all screen sizes (5”, 7”, and 8”).
• All other models: Only compatible in vehicles equipped with the 7” or 8” screen. Vehicles equipped with the 5” screen are not compatible.
• If you are installing the AmpPRO in a vehicle that is not equipped with a factory amplifier, you must add an amplifier to the vehicle's speakers, as the factory radio will no longer have a 4 channel variable output after it has been re-configured by the AmpPRO. For example, this will not work to add only a subwoofer to a non-amplified vehicle, as the radio will no longer power the cabin speakers properly.
• Non-amplified vehicles equipped with an Active Noise Cancellation (ANC) system require the ANC module to be bypassed. This can be done manually or with the ANC bypass harness ANC-CH01 (coming soon). Click here to see how to tell the difference between an amplifier and an ANC module and for module locations.
  • The following vehicles have an ANC module that needs to be bypassed:
    • 2017-2019 Chrysler Pacifica
    • 2015-2016 Jeep Grand Cherokee
    • 2019 RAM Truck (Non-Classic)
