When adding a subwoofer to a vehicle equipped with
ANC, the ANC system will attempt to cancel out the bass
frequencies being generated by the aftermarket subwoofer.
This results in unwanted "noise" being produced by the
factory speakers.
Identifying ANC in the Vehicle
Vehicles with multiple microphones located in the door
panels or headliner locations will usually be equipped with
ANC. If you are unsure, the ANC-CH02 can be installed with
no negative effect on vehicles not equipped with ANC.
Bypassing the ANC Signal
1. Access the factory amplier (see location info to the right).
2. Disconnect the 10-pin factory harness from the amplier.
3. Plug in the ANC-CH02 harness into the amplier.
4. Connect the 10-pin factory harness to the ANC-CH02.

separately) would need to be installed at the ANC module behind the Passenger Side Rear Quarter Panel to deactivate the
ANC system.
