About: PAC AmpPro AP4-GM71 Amplifier Interface for Select Chevrolet and GMC
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. Factory amplifier must be removed from vehicle when installing this interface.
The AP4-GM71 provides a 6-channel pre-amp output for use with aftermarket audio equipment. The AP4-GM71 delivers a variable 5v RMS pre-amp output with fading, balance, equalization, and level control capabilities. The module also retains all audio from other vehicle features such as factory navigation prompts, Bluetooth, OnStar, and parking sensor chimes. A data controlled remote amplifier turn on wire is also provided by the AP4-GM71. The module also provides a variable 2-channel fiber optic digital audio output (TOSLINK).
