FAQ

Is there another way to disable my ANC?

Yes there are a few other ways.

Cut the wires at the factory amp. (absolutely not recommended)
Prop the headliner and disconnect the ANC microphones (does not always work)
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
