Aftermarket Amplifier Integration Made Easy

Many of today’s vehicles have fancy radios with lots of features, Bluetooth, vehicle settings, climate control, amplified audio systems and more. When you want to get better quality sound and more power, adding an amplifier is great way to improve your audio system. This can be difficult and time consuming on a-lot of vehicles. PAC simplifies this with AmpPRO, the plug and play amplifier integration solution.

  • Vehicle Specific Interface with RCA Pre-Outs
  • Vehicle Specific ‘T’ Harness
  • Subwoofer (CH5+6) Level Controller port,

Compatablity Notes

The vehicle must have the 52-PIN Chrysler-style connector at the OEM radio to be compatible.

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.

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).

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)


Some Chrysler / Jeep / Dodge vehicles may require some time from after the radio is removed and re installed to detect all factory features. This is not a limitation of the interface more of the vehicle. If you remove and reinstall the radio, you may need to start and shut down the vehicle a few times.
