This GMC Buick ANC bypass harness was designed for vehicles that have the factory Bose amplifier and an RPO code of  UQA,UQF,UQS,UQP. This chevy ANC bypass harness is ideal for disabling and preventing feed back of the factory ANC system, when adding an aftermarket subwoofer. This harness works with all Chevy, GMC, Buick and Cadillac models that have the Bose with ANC.

The Active Noise Cancellation, or ANC, in your vehicle is designed to pick up on low frequency road noise and cancels out any undesirable sounds, making your drive a quieter and smoother ride. The ANC in your vehicle can become a major headache when adding aftermarket equipment, such as subwoofers or speakers. The ANC microphones will send feedback from the aftermarket subs through the speakers, making an odd sound or random "pops" that come and go, distorting your music.
