Cadillac 2016-2020 (multi RPO) — ANC-GMH3

This active noise canceling bypass harness ensures smooth speaker and subwoofer upgrades in non-amplified GM vehicles with ANC audio systems in 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.
