Axxess ANC-GMH3 – Active Noise Cancellation (ANC) Bypass Harness
The Axxess ANC-GMH3 is an Active Noise Cancellation (ANC) bypass harness designed for select GM vehicles equipped with factory ANC audio systems. It allows installers to bypass the factory ANC system when adding aftermarket speakers, subwoofers, amplifiers, or other audio upgrades.
Factory ANC systems use microphones and speaker output to reduce road and cabin noise. When aftermarket audio equipment is added, the ANC system can sometimes create unwanted sounds or interfere with the upgraded system. The ANC-GMH3 helps eliminate those issues by disabling the ANC function while allowing the upgraded audio system to operate properly.
