The Factory Sound System Upgrade Solution

Today's modern vehicle audio systems are becoming increasingly more sophisticated and complex. PAC engineered AmpPRO to drastically simplify the installation of upgraded amplifiers in data-bus controlled amplified sound systems. AmpPRO allows you to keep the original radio's fit, finish and features while giving you the freedom to improve the audio performance in record time!

PAC’s new AmpPRO line offers a full suite of features that provide seamless integration of new aftermarket amplifiers with a vehicle’s factory radio and speakers by easily installing the AmpPRO module and harness between the vehicle’s head unit and amplifier. The AmpPRO line retains the vehicle’s original factory audio features, while allowing a better audio performance from high quality aftermarket amplifiers. It eliminates the need for summing devices and audio correcting devices, making aftermarket amp installation a much faster and less complicated process – saving the installer a lot of time!


A TOSLink optical adapter, APA-TOS1, is an available option to provide a pure digital output for an aftermarket amplifier installation with AmpPRO.
