AXXESS BY METRA
ANC-GMH1

Description

This active noise canceling bypass harness ensures smooth speaker and subwoofer upgrades in 2014-2023 GM vehicles with amplified ANC audio systems and covers a variety of RPOs. It maintains proper communication between audio equipment and the ANC system, giving listeners full control over their music without sound distortion, interference, or conflict between devices. Within ANC systems, built-in microphones detect and eliminate background noise in a vehicle but often mistake aftermarket speakers and subwoofer vibrations for interference, creating compatibility issues. Audio system upgrades can also affect a vehicle’s sensitive electronics, causing system errors. Axxess’s ANC bypass harnesses prevent these issues while giving installers more flexibility in their audio system design, as they will no longer have to avoid ANC microphones within the vehicle’s interior. All Axxess products come with full support from Axxess integration professionals, who are available to call for technical support seven days per week.
