I've got a 2002 A4 with the Symphony H/U 6 disc in dash with Bose spakers. I want to replace it with an 2 din aftermarket deck. Here are the one's I'm looking at: Alping IVA-W200, Eclipse AVN5500, Kenwood Excelon DDX-8017 or Pioneer AVIC-N2. Any suggestions would be great. I know the Pioneer and Eclipse have built in nav. Although it would be nice to have its not a deciding factor. I want one that will give me the best sound quality. I'll be replacing the factory speakers with better comp. speakers and a 4ch amp.

Also are there any good dash kits? wiring harness?

 

they are all very nice decks and will sound good only thing is the n2 is not a double din its a flip out...look at the AVIC Z1...double din monitor dvd, and such with a 30gb harddrive built in
