wlffinch Posted August 24, 2017 Report Share Posted August 24, 2017 The ANC on my 2013 C-Max hybrid has recently gone nuts. It is putting out noise (loud low end drone) when no engine noise exists. I confirmed this by pulling the fuse. Drone goes away. Unfortunately, so does the stereo. (This is a non Sony 6 speaker stereo). My Ford dealer says they have never heard of such a thing. The car is out of warranty and I don't want to spend several hundred dollars in labor while the technicians play with everything. Disabling the mics in the headliner as other threads suggest seems like a mess as short of dropping the whole thing (no clue here) there's no access. I would happily do without the ANC if I could power up the amp from another source. Can anyone suggest how this might be done? I have seen nothing that tells me where the thing is in the first place. Any other suggestions? Quote Link to comment Share on other sites More sharing options...
obob Posted August 24, 2017 Report Share Posted August 24, 2017 (edited) It looks like you have done some nice work figuring out things. I use google to search this site, not this site's search. I found the following link with a google search "fordcmaxhybridforum active noise cancel" Maybe this will help http://fordcmaxhybridforum.com/topic/6669-how-to-quick-and-easy-reversible-anc-delete/ as far as " My Ford dealer says they have never heard of such a thing" this forum is a better source of information for some things.

wlffinch Posted August 25, 2017 Author Report Share Posted August 25, 2017 Thanks, obob. This solved the problem and it was easy to implement given the detail in your link. :) I couldn't find that thread as a newbie here. Maybe this post will clarify things for others as the sound I was having was so annoying as to make a good car bad. Thanks again. Quote Link to comment Share on other sites More sharing options...
