PAC - AmpPRO4 Amp Integration Interface for 2019 and Up Cadillac, Chevrolet, GMC, Hummer with AVB Ethernet Bose - Black/Blue

Today's modern vehicle audio systems are becoming increasingly more sophisticated and complex. PAC® Audio engineered this AmpPRO4 Interface to improve your vehicle's audio performance while keeping the original radio’s fit and finish. The AP4-GM71 simplifies the installation of upgraded amplifiers in select GM® vehicles with AVB Ethernet/Bose® factory amplified systems. This amplifier integration interface also allows you to retain important factory features, including GM® Super Cruise feature, and provides navigation outputs. It also comes with a sublevel controller. Please note the factory amp must be removed from the vehicle while installing this interface. When installing into any vehicle other than Silverado or Sierra, you must be using rev 2.3.1.5 as it contains the necessary connectors for these vehicles.
