Good install kit
2000 Audi A4
Crutchfield Customer Review (What's this?)
Works quite well in my 2000 A4 though it seems like it's just a hair too tall and difficult to install the top Audi trim piece.
Pros: Crutchfield had the best price online and fast shipping. Kit does it's job and looks good.
Cons: Slightly too tall it seems.
