AmpPRO simplifies the installation of upgraded amplifiers in data-bus-controlled amplified sound systems. With AmpPRO, you can improve audio performance while keeping an original radio’s fit, finish, and features.


This product is compatible with data-bus-controlled amplified systems only. 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. Vehicle manufacturers do not always brand compatible systems. Unbranded amplified systems are generally identified by locating a center channel speaker or subwoofer.
