PAC AmpPRO SUB GM/Holden Amplifier Integration Interface

Compatablity Notes In some non-Bose radios, there may be absence of audio from the left channel when in AM, FM, and XM sources. The APSUB-GM61 is capable of providing a work-around by passing the right channel audio through the left and right channels when in the AM, FM and XM sources. All other sources will still offer left and right separation. See the troubleshooting section on page 6 of manual for additional details Must have Infotainment system RPO code IO5 or IO6 to be compatible. When the bass level control knob is not connected to the APSUB-GM61, the output level will default to 100% If originally equipped, the factory amplifier must remain in the vehicle, and connected after the APSUB-GM61 has been installed. The factory radio’s speed controlled volume and surround sound mode are not supported by the APSUB-GM61 outputs. If the vehicle is equipped with Active Noise Cancellation (ANC), the ANC can be disabled using the included ANC-GM03 harness. See page 3. 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.
