in my wife's 2021 Ford Expedition she has the same problem, In my 2020 Ford F150 Lariat I did not have this problem and In my 2021 PB I currently do not have this problem only in her Expedition and it drives me crazy when I drive it.
anyone else have any of their B&O speakers sound like they are blown? my passenger side rear door sometimes sounds like it is blown, and other times sounds fine. I almost think maybe there is some kind of interference. I have called Ford and they said they have never had a speaker come back...
