Front Door Speakers in a BMW 3 Series
Has anyone changed the speakers and tweeters in the front doors of thier BMW 3 Series? Mine did not come with the Harmon/Kardon factory upgrade, so I'm looking to install some new speakers.
However my brands of choice are Rockford Fosgate or Alpine, BUT www.crutchfield.com says that neither RF or Alpine's 6-1/2" speakers will fit in the front doors of my car.
The only front speakers it says will fit are some Kicker speakers I've never heard of before. The only difference I can see between the Kicker speakers and the Alpine speakers are a top mount depth of 2" on the Kickers' and 2-1/4" on the Alpine type S ones.
Surely 1/4" is a small enough distance to allow the speakers to have a modified fit, but crutchfield doesn't even list any speakers that will have a modified fit for the car.
So I'm just asking if anyone has installed any aftermarket speakers in thier 3 Series (other than the Kickers which apparently fit)
