aftermarket speaker slightly hitting the window

Jerezblack.m3 · 12-04-2023, 10:05 AM

Hello, I was wondering if you guys could help me with a problem I'm having. I have an E92 HiFi system, and I bought an aftermarket speaker for my front doors – the Alpine S2-240C. While I managed to mount them properly, the window slightly touches the back of the speaker. The window does roll up and down, but you can see that the window pushes the speakers a little bit out. Is there any way I could create more clearance?

There are a list of speakers that fit in the Audio build thread at the top of
the forum page in the sticky's . The coupe door is extra thin and the specs
are in there. If you bought one that is not a BMW compatible you could try
shimming it to the outside. .

There are many more BMW compatible speakers now but you have to be
aware the couple doors are extra thin,

I had the same issue with Eton 2 compo speakers, had to trim a bit of the plastic doorboard speaker surroundings/mounting plate to move it away/more inboard from the sliding window... also make sure that the foam water barrier is not torn... and sound deaden the door skin and doorboard... and the area under the tweeters location, surprisingly a lot of NVH/aero is coming through there...

I think they only really fit the sedan. I just installed the same speakers on my car with no issues.
