2012 equinox looking to disconnect active noise control.
Getting feedback and signal noise thru speakers.

How can this be disconnected?

I have also installed aftermarket speakers,amps,even
the lastest audio control processor / crossover eq.

Some said to cut the microphones. Where are they located?

I believe the factory stereo has on/off for noise control. Check your manual.

went through the manual, and nothing on radio prompts.

i see the microphones in headliner. guess ill cover them and see

if it helps

remove the aftermarket junk and restore it back to factory. these new cars are built to be equipped with factory equipment only. another reason for car manufacturers to incorporate the ICS to new vehicles, so people wont change the radio's and other items.

The active noise control can't be deactivated unless you yank the subwoofer's connections, remove the amp that goes to it or rip the audio system out (and you'll likely lose the HVAC controls if you do that). My wife has a 'Nox, active noise cancellation is fixed. It's interlinked with the audio system and subwoofer in the rear. Don't mess with it; if you do, you'll dislike the result. I don't know if the mic being deactivated/cut will do what you want; the result will be an open loop amplifier (don't know what this system will do) and a check vehicle warning in the dash.

We had it once, and only once, for some reason deactivate for about 10 minutes. The interior was BOOMY loud, a really 'thrum' like uncomfortable boom, typical for a large displacement 4 banger. After the car was cut off and restarted it never, ever did that again (been 19 months since it happened). It was a lesson in how well the active noise cancellation really works and why the Equinox can be so quiet inside at lower RPMs. Most 4 bangers aren't this quiet at low RPM.

And why the audio controls interlinked to the HVAC? The two seem to be interlinked based on a TSB from a while back (early Equinox/Terrain models had a defroster issue that was fixed by reprogramming the HVAC module). Audio systems in the 'Nox can be actively controlled by OnStar (fan turned down and audio system muted when announcements are made), hence the HVAC and audio systems seem to be interconnected.

Just leave the system alone.

Also why I won't touch a used car with aftermarket audio systems with a 10 foot pole.

Usually a horrible hack job, and if not, it's completely screwing up the car's overall electronics systems.

This vehicle came with the pioneer system which was ok but now i have a

full JL audio set up custom fiber glass box in spare tire well (2) JL amps the brand

new audio control processor made for these new integrated vehicles.

JL audio separates in doors.

As far as active noise control, got schematic for radio unit. Clipped the

wire to the rear for active control. System is perfect no hiss no feedback

and the sound is amazing with no fazing problems. One issue is the turn signal

blinker is quieter but who cares.

I would not attempt to install an aftermarket system in a new car. Too many other things are tied into that. This has been the case since at least 2000 and likely even older GM vehicles.

how long before we find out that active noise 'control' causes
cancer
impotence
bad breath
etc
