All the modification are done on the speakers not on the car.
I don't know if other kinds of speakers will need any modifications.
But one thing sure is that other speaker magnet are pretty big and heavy that it might require cutting a hole on the back sheet metal.
I personally would not cut a hole in a new bmw
