PAC AmpPro4 Sound System Upgrade for Select GM Models w/ Bose Radio AP4-GM61

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 AP4-GM61 provides 6-Channel pre-amp outputs (front and rear, left and right, along with a center channel output and non-fading output for subwoofer output) for use with aftermarket audio equipment. Using the full range, fixed level head unit output, in conjunction with most, the AP4-GM61 delivers variable 5v RMS pre-amp outputs 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, parking sensor chimes,  safety alerts, reminders, and infotainment. A data-controlled remote amplifier turn-on wire is also provided by the AP4-GM61. The module also provides a variable 2-channel fiber optic digital audio output (TOSLINK).

• TOSLINK optical output
• Plug-and-play installation
• Sub level controller (included)
• Front, rear, center, and sub preamp outputs (5 volt)
• Provides variable volume, fade, balance, bass, mid and treble audio settings
• Simplifies amplifier installation in data-bus controlled factory sound systems
• Retains warning chimes, navigation prompts, Bluetooth, and telematic audio (if equipped)
