I just bought a 2003 Audi A4 with the standard Audi Symphony system and it's pretty good, but I'm looking for a bit more. I like factory head units mostly because I think every other head unit I've seen is horribly ugly and never matches the rest of the interior so that's staying.

I'm thinking of upgrading my speakers to the Infinity Reference 5022i line. They are from $65-110 a pair. Has anyone used these and what is your experience?

I'm also thinking of doing the standard Dynamat speaker kit install on all 4 5.25" speakers (one in each door.) Anyone think that's worth it? They are $25 per pair so that adds another $50.

Please share your thoughts and if you have them a better recommendation. I'm looking to stay around $100 per pair. I have a buddy that works at Best Buy that might be able to get me a discount on anything there too so that helps.
