Transform Your GM Audio

Upgrade your GM vehicle’s sound system by replacing the weak factory amplifier with a high-performance aftermarket amp. PAC’s AmpPRO interface, featuring a module and vehicle-specific T-harness, makes installation quick and hassle-free. Keep all your factory features intact, including warning chimes, navigation prompts, and Bluetooth functions, while enjoying premium audio quality.

Hassle-Free Amp Upgrade

Install your aftermarket amplifier effortlessly with PAC’s AmpPRO T-harness, which plugs directly into your factory radio and vehicle harness. The compact module fits behind the dash and converts speaker outputs into six preamp-level outputs—front, rear, center, and sub. Maintain full control of volume, balance, and fade while enjoying enhanced audio performance.

Precision Audio Control

Take full control of your GM audio system with the AmpPRO PC App on a Windows computer. Access your factory 3-band parametric EQ to fine-tune every detail of your sound. You can also adjust chime volume, set the system’s minimum volume, and update firmware for peak performance.
