2004 A6 2.7T audio upgrade

[vghostine]

Hey guys, my car has the 8 speaker bose system with sub but I want to replace that system to get a better sub noise and all. Is there a way to just replace the sub on the bose system + Amp or do I really have to replace everything, including radio? FYI: Where should I go for good but not too expensive systems. I dont feel like spending 2000$.

Its been a while I didnt check this thread and still no one posted anything??? Seriously? Where is the love dammit? Anyways, for your reference, I am checking out the ALPINE systems to replace by Bose radio. I want to use my iphone and MP3 and the stock radio of the A6 2004 doesn't even support MP3...so to keep up with this era of MP3 and Iphone usage, I must bid farewell to BOSE (i loved every bit of it) and say hi to the new modern technology.
