It will work. It just won't sound the way it should. The coding in your car is currently set to modify the sound to compensate for shit speakers.

When you add the Alpine Kit it needs to be changed from "base" to "hi-fi". This flattens the EQ curve and sends an unmodified signal to the speakers.

I had the Alpine kit in my 135i for about a week before it was coded and trust me. It's night and day difference.
