Paul Chin Report post Posted June 30, 2013 I installed an aftermarket subwoofer and amplifier on my 2013 FFH and ran into problems with the active noise cancellation (ANC). Problem is, that whenever the ANC kicks (1000-1500 RPM), the amplifier amplifies the ANC frequency and I get a terribly loud vibration from my subs. I had a small work around by turning down the gain on the amplifier but the feedback still occurs, just not as often and not as loud. I read on forums with 2013 accords, escalades, and other cars that have ANC, and their workaround to disable the ANC is to unplug the mics in the headliner. Problem is that I'm not sure if the mics for the ANC are also the mics for the bluetooth calling and voice commands. The Honda ANCs can be disabled through going into diagnostic mode in the head unit. I tried this with my MyFordTouch and I couldnt find such an option under diagnostic mode. Anyone know of any way to disable the ANC without losing the mic for bluetooth calling/voice commands? Quote Share this post Link to post Share on other sites
