Did you push back on the dealer and show them that there are supposed to be speakers in that bottom opening, not fake ones?I just came back from the dealership and they removed the rear door panels and showed me the "dummy" speakers in the bottom set of speakers in the rear doors. They claim that this is how it is supposed to be and said that another Lux+ with ML also had the same setup. The speaker map shows that they are speakers in that location.
