Axxess ANC-GMH1


This active noise canceling bypass harness ensures smooth speaker and subwoofer upgrades in Ford vehicles with ANC audio systems. 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.

The absolute best quality and shipping

Honest opinion here! I don’t think I would ever order parts for my sound system from anybody else. This is by far the best experience I have received since I had my sound system installed in my truck. They was very fast on delivery and when the product made it, it works perfect. I would’ve shown a picture, but as soon as my part made it, I installed it in my truck. Overall, I’m very very happy.

a must have if you install aftermarket sub and amo

this harness only took literally 2mins to put in! its as simple as locating the factory bose amp and unplugging the ANC harness, plug that in this harness and the other end in the bose amp, all plugs are keyed so you cant mess this up. before I installed this harness, I had a lot of hum noise and feedback through my subwoofer. After this it's completely gone. It seems like it lessend the noise in the cabin altogether to be honest too. I always thought it was a little noisy cabin. and now it sounds like it should!
