It cannot be said that it is because the Coupe and Convertible require different drivers to sound the same as the Sedan, as you can get the same set of Focal 100KP components that fit all the models and still sound great in all of them.
Do the Focal's 100 4" fit without any major mods in the E90's sedan front doors?
