I have installed this in the front doors of a 96 Jetta for a friend. By the way you have to disconect the factory dash tweeters(otherwise you'll have 2 ohms load, and even if you wire them in 8ohms sound it's really bad). No sound deadening material was used and with small adjustments they fit great. Good sound quality with clear mids and highs. Didn't get powerful bass but I wasn't aspecting that anyways. They do a great job in companion with 2 12" polk audio dxi subwoofer.
