APSUB-GM61
Introduction and Features
The APSUB-GM61 provides a 2-channel non-fading output for use with an aftermarket amplifier and subwoofer. Using
the full range, fixed level head unit output, in conjunction with MOST data, the APSUB-GM61 delivers a variable 5v RMS
pre-amp output with bass equalization and level control capabilities. The signal has a 350Hz / 24dB Linkwitz-Riley low
pass filter applied. A data controlled remote amplifier turn on wire is also provided by the APSUB-GM61.
Important Notes
1. This interface is compatible in vehicles with or without Bose that are equipped with IO4, IO5 or IO6 model radios.
2. 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 for additional details.
3. If originally equipped, the factory amplifier must remain in the vehicle, and connected after the APSUB-GM61 has been installed.
4. The remote output is rated at 2A of current. If more current is needed, an external relay must be used.
5. When the bass level control knob is not connected to the APSUB-GM61, the output level will default to 100%.
6. The level control knob must be connected in order to manually adjust the minimum volume settings.
7. The minimum volume level is set to a default value. If you are happy with this level in your particular application, then
additional adjustment is not required. Please refer to the Setup and Configuration section on page 2 for more details.
8. The factory radio's speed controlled volume and surround sound mode are not supported by the APSUB-GM61 outputs.
9. No adjustments can be made manually using the programming button or the factory SWC when the module is connected to a PC.
10. If the vehicle is equipped with Active Noise Cancellation (ANC), the ANC can be disabled using the included ANC-GM03
harness. See page 3.
The aftermarket amplifier must have a very solid ground and the amplifier power/ground connections
should be made before connecting the RCA's or Remote Turn On to the APSUB-GM61
