Simply put, they don't fit. The description says they fit the front door speakers just like the Revain parts checker, even the SCOSCHE website says they fit. The problem is that the factory door speakers are fixed with three screws, in this adapter there are FOUR. I couldn't even get it right, the adapter doesn't even fit, it's interfering with parts of the door panel. As far as I can tell, they don't work with other speakers in the car either. A little research shows that this is not a difference between the standard system and the Harman Kardon system. (Mine isn't a Harman Kardon btw) Look at the attached pictures to see you can see the SCOSCHE adapter, the standard speaker and its position and the SCOSCHE will not fit. I'm sure they fit somewhat, but they don't. it is an e46 325i.
