Active Noise Cancelling question

62 dB at idol or driving?
I can download a sound meter on my phone and test it out.

62 db doing 70 mph on highway

Can anyone tell me how I can see if my ANC has been bypassed somehow by the previous owner? I can hear my exhaust and XT tires hum quite clear in my limited. Have been wondering if it isn’t working because I have a lot of cabin noise. H/K 19 speaker system if that matters

The ANC is the silver box under the drivers seat. Pull the seat all the way forward and up and look at it from the rear seat. You will see a white plug in the rear right corner. If there is a jumper or pig tail between the white plug and the box, it’s been bypassed.

If there are wires pulled out of the white plug, then they bypassed by disconnecting the mics.

The other way people do it is they disconnect the mics from in the headliner. Why, I don’t know.

Hope this helps.

@bigdodge : Tested it out today. 70-75 mph on the highway I’m running 75dB - nothing but a/c on. Radio muted, windows up.

@wsutard1 :
Pics of my anc box attached. Don’t see any pigtail and wires all seem to be intact. There are two wires (green and white) that are pulled up from the rest of the bunch. Is this normal?
