My sound system just keeps getting better! Matt used his awesome soldering skillz and helped me do the install last night. We installed the Bose mid/tweeters that the BMW tweeters displaced. Since there wasn't much room, mounting them behind the large door grills was the only option, besides cutting a hole in the door panel. I must say, it sounds very nice!
Here is a pic with the grill in place, looks totally stock, other than the Bose badge.
The Bose mid/tweeter is hot glued to the back of the main grill.
And the whole 3-way system: (I still need to securely mount the tweeter)
Thanks Matt!!!!!!
