Description
This item is brand-new, factory sealed.
This active noise canceling bypass harness provides a reliable solution for upgrading speakers and subwoofers in non amplified GM vehicles with ANC audio systems across various RPO configurations. It ensures seamless communication between the new audio components and the ANC system allowing listeners to enjoy powerful clear sound without distortion interference or signal conflict. The factory ANC system uses built in microphones to cancel background noise but these can misinterpret the deep tones of aftermarket speakers or subwoofers as unwanted sound leading to feedback or performance issues. This harness prevents those problems by properly bypassing the ANC system while preserving your vehicle electronics and system integrity. It also gives installers more flexibility in their setup as they no longer need to avoid the ANC microphones within the vehicle interior. Built with durable materials and precise connectors the Axxess ANC bypass harness offers a smooth plug and play installation process. Supported by the Axxess integration team available seven days per week this harness ensures professional grade performance and protection for your GM vehicle audio upgrade.
