With the AmpPRO AP4-GM71, you can improve your vehicle’s audio performance while keeping an original radio’s fit, finish, and features. The AmpPRO AP4-GM71 is compatible with the GM Super Cruise Feature. Vehicle Compatibility: The PAC AmpPRO AP4-GM71 can be used in the following 2019-2024 GM vehicles equipped with a factory amplified Bose sound system. Note: Your vehicle must have a Bose Infotainment system RPO code IOS, IOT, or IOK to be compatible. To verify the “IO” RPO code on your vehicle, check the glove compartment 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. 6Ch Pre-Outs: The PAC AmpPRO AP4-GM71 provides a 6-channel pre-amp output for use with aftermarket amplifiers. Using the full-range, fixed level factory radio output, in conjunction with data-bus CAN messages, the AP4-GM71 delivers a variable 5V RMS pre-amp output with fading, balance, equalization, and level control capabilities. Pre-outs include Left/Right Front, Left/Right Rear, and two non-fading (Sub). Non-Fading Level Control Knob: Channel 5/6 (Sub) of the AP4-GM71 is a non-fading output. The output level of channel 5/6 can be controlled using the supplied level control knob. The level control knob comes with a 6′ cable which plugs into the interface module and should be mounted in an accessible location. If the level control knob is not connected, the Subwoofer channel’s output volume will always be at maximum. Note: If running the Subwoofer output to an amplifier requiring 2 channels of input, an RCA “Y” adapter will be required (sold separately). Data Controlled Remote Turn-On: A data controlled remote amplifier turn on wire is also provided by the PAC AmpPRO AP4-GM71. The remote turn-on is rated at 2A of current. If more current is needed an external relay must be used. Retained Factory Audio Features: The PAC AmpPRO AP4-GM71 also retains all audio from other vehicle features such as factory navigation prompts, Bluetooth, OnStar, parking sensor chimes, safety alerts, reminders and infotainment. Minimum Volume: If the minimum volume of your factory radio is too loud once the AP4-GM71 is installed, you can manually set the level of the minimum volume using either the programming button on the side of the interface or the factory SWC (Steering Wheel Controls) in conjunction with the supplied level control knob. You can also use AmpPRO PC app. AmpPRO PC App: Using the AmpPRO PC App (for Windows PC only) allows you to configure user interface options such as Minimum Volume Level, Chime Volume Level, and a 3-Band EQ from your Windows computer or laptop. The app can also be used to update product firmware. Minimum Volume Level: From the app you can set the minimum volume level of the factory radio. 3-Band EQ: Enables the 3-band EQ (Bass-Mid-Treble) with frequency and Q-factory adjustment. The Bass Frequency can be set to 60, 80, 100, or 120Hz; while the Bass Q-Factor can be set to 0.5, 1.0, 1.5, or 2.0. The Mid Frequency can be set to 500, 1k, 1.5k, or 2.5k; while the Mid Q-Factor can be set to 0.75, 1.0, 1.25, or 1.5. The Treble Frequency can be set to 7.5k, 10k, 12.5k, or 15k; while the Treble Q-Factory can be set to 0.75 or 1.25. Firmware: The AmpPRO app will also allow you to update the interface with new firmware as it becomes available. Note: These AmpPRO PC App settings can be adjusted with the module installed in the vehicle or on the bench. However, it is recommended to make the adjustments with the module installed, and the factory radio on so that the changes can be heard. Dip Switch: Set dip switch 2 to “ON” to lower the RCA output voltage to 4V. Set the dip switch 2 “OFF” to keep the RCA output voltage at 5V. Dip switches 1-3-4 are not used. Toslink Adapter: The AP4-GM71 has a Toslink digital audio output that provides a variable 2-channel signal. No optical digital cable is included with the interface.
