What is ANC?

What is ANC?

The symptoms will only happen when the vehicle is in drive or reverse.

PAC and Metra(Axxess) sell stolen copies of our ANC bypass harness. Some of the fitment & information they provide is incorrect and does not reflect on our products.

Our Bose ANC bypass harness is the first in the world. We developed the Bose ANC bypass harness to disable the Bose ANC microphones in your vehicles. this aids in installing a subwoofer/s into your vehicle that has a Bose AMP or a factory none Bose amplifier preventing any feedback from happening. If the Bose ANC module in these vehicles is not bypassed you will get a back feed into the aftermarket amplifier that will damage the amp and subwoofer. bypassing thus disabling the ANC keeps that from happening; it takes 30 seconds to do so.

Our Bose ANC Bypass plugs in between the data plug on the factory Bose Amp or Factory Amp itself (picture reference below for plug-in location). This will disable the ANC microphones in the vehicle without affecting anything in the factory system.

Our ANC designs do not disable any factory features! Just the ANC. Some knockoffs will disable speakers.

This ANC bypass is designed to disable the ANC in any Chevy, GMC, Cadillac and Buick vehicle with the BOSE/None Bose amplifier with ANC.

  • 2014-2022 ONLY
  • Microphone will be in the rear part of the vehicle in the headliner. (microphones above the driver of passenger seat are for Bluetooth)

Some vehicles have the amplifier but not the tunning and use the same connectors and ANC features.

  • Trunk over wheel well
  • Under center console


  • Trunk behind the taillight over wheel well


Is there another way to disable my ANC?

Yes there are a few other ways.

  1. Cut the wires at the factory amp. (absolutely not recommended)
  2. Prop the headliner and disconnect the ANC microphones (does not always work)
  3. Some vehicles have the ability to disable in the software. (this can turn back on by itself)
After about 20 minutes that I turned off my vehicle, my subs will start to make a loud rumble. Why? Is this ANC?

NO, this happens when the vehicles security system sends a signal to the radio or amplifier that triggers the LOC or amp on.

Using DC offset OR audio turn-on will fix the problem for you. This can happen with vehicles regardless of having ANC.

Where do I plug in this bypass?

There are 3 places you can and it depends on the vehicle manufacturer and equipment.

  • Factory radio
  • Factory amplifier
  • Factory ANC module

Our harnesses have a 'where to plug in at' section for each bypass harness.
