I'm seeing if anyone has upgraded their stock Blaupunkt tweeters that are located in the door and are willing to part with them. Or if someone may know of where to purchase the stock / know the part number / where to buy or even an upgrade that is the same size and will fit in the same hole would work as long as it looks clean. My roadster didn't come with that option and I want to open up the sound a little but also trying to keep it looking stock as well. Thanks!
