Hi Guys, will post pics soon, just bought a 2004 Audi S4 Avant Tiptronic... it's a dream! Got lots of ideas for the car... Will be upgrading to the RNS-E right away, and upgrading the stereo... Bought a Boston Acoustic amp (GTA-1005 - 5 channel amp 50x4 + 250x1 into 4ohm; 80x4 + 400x1 into 2ohm) that has line level inputs so that you can just unplug the factory bose amp and use the leads there and wire up the speaker outputs as well... I'll take step by step photos when I'm done. I also will be installing and APR cat back exhaust myself, seems easy enough to do, so I'll document that as well. One thing I'm looking for are a cheap place to find interior trim... I have the wood trim and would like satin nickel or brush metal finish anyone knows, let me know!

 

Fantastic and welcome to the forum. Love the Avant.
