Simple to Install
Today's modern vehicle audio systems are becoming increasingly more sophisticated and complex. PAC engineered AmpPRO to dramatically 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!

The package's T-harness plugs into the factory radio and vehicle harness. The small module fits behind the dash, converting your radio's speaker outputs into six preamp-level outputs ready for connection to your amp.

The factory amplifier needs to be left connected in the vehicle. The factory radio controls, such as volume, balance, and fade, will work as before for your front and rear speakers. A separate wired remote level control lets you adjust the volume of the subwoofer channels from your front seat. The interface also provides an optical digital output for your high-end digital processors and amplifiers to handle.

How it works:

Notes:

• Must have BOSE factory sound system.
• Must have Infotainment system RPO code IO5 or IO6 to be compatible.
• To verify the "IO" RPO code on your vehicle, check the glove compartment or spare tire well for a silver sticker with these codes. If this sticker is not present, you must scan the QR code on the GM label found in the driver's door jamb. The RPO codes will be listed in alphabetical order in either scenario.
