It seems if you want to change out the subs on a Honda (and a number of other cars) you have to disable the ANC. I imagine I'm not the only one who wants to keep the ANC. I could weigh down my car with sound deadening material but that might not be an option for cost or access reasons. Seems like you can certainly buy better speakers, head units, amps, security alarms than the OEMs after market but I haven't found an ANC after market yet.
