I own a 2016 fusion energi titanium with a Sony sound system. I have replaced all door speakers with top quality component speakers and removed the 6X9 woofers in the rear deck. I built custom boxes and put 2 10" sub woofers in the back and added a 5 channel amp to drive everything. I also have a signal processor between the factory sony amp and the inputs to my aftermarket amp. I also want to eliminate this ANC issue and I tried disconnecting the 3 microphones inside of the cabin and when I disconnected them, I lost my ability to use hands free operation with my SYNC and it cound not hear my commands. I had to hook them back up and I would like to know if anyone has figured out how to disable this feature? What does iCE stand for?
