I'm thinking of replacing the standard HU with an Alpine 9887 (i think thats the number). Does anyone have any pictures of what a unit like this will look like in an S4? I'm worried about spoiling the look of the car.

If anyone has, in terms of sound, is it worth it?

I think if I do in time I'll go for componet speakers, a couple of amps and a sub. Again any pictures of builds in B5 avants would be good.
