What is ANC?

What is ANC?

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

  • Feedback when the sub is playing
  • Thumping of rapid off beat rattling from the sub
  • Humming

ANC is not used in vehicles that are designed for offroad use. Microphones can be found in the headliner.

For Cadillac CT6 ANC ANC bypass harness. The amplifier will be located in the trunk of the car. This Cadillac ANC bypass harness is keyed and will only fit in the speaker/Data port of the amplifier.

Connection is done at the amplifier located in the rear trunk on the driver side.  Verify connection before ordering.

 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.

Designed and built in the U.S.A by LLJ Customs. Stolen by PAC Audio and METRA elec.

This ANC bypass is designed to disable the ANC in any Cadillac ct6 vehicle with the BOSE/None Bose amplifier with ANC.

FAQ

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.
