What is the tweeter size for an e36? Im going to order some tonight (or I guess this morning) because one of mine popped out of the door panel and had no speaker behind it, so whats the size I should be looking for and what are some good brands for tweeters?

You've got a choice of metallic or silk domed; personal taste, really. Some say that the metal domes are harsh or brittle and the silks are smoother/softer.

MBQuart, Focal, FLS (from Maxima on this board, if he has singles availble) and a bunch of others.

You might just want to get a used OEM replacement if you plan to keep the HU and amp you've got in the car now.

Where can I get an OEM replacement??

the dealer. here. ebay. junkyard

seriously, this is covered a whole lot, you should really search, or use the wonderful stickies at the top of the page.

best of luck, and you want a 92-EARLY95 tweeter. 96+ are different, they'll fall right through your door.
