I'm assuming you have taken one panel off before and not the other?
Unfotunately from what I've noticed, door panels will never be as tight after they have been removed. Its a shame b/c I like to replace the factory speakers, but that situation alone keeps me away from the job.
AMG can't build an NA engine that can compete with M engines, so they stick in a supercharger and say their cars are faster. BMW could simply do the same, but they don't out of principle.</span>
