hi i have a 2003 1.8t audi a4 which has the audi symphony sound system. i was wondering how many ohms the front door speakers run off and the size of the stock speakers and how hard it is replace these speakers with aftermarket speakers. also if anyone has a good aftermarket speaker which is relatively easy to install in place of the stock symphony speakers.

 

I'm sure that your car has 6.5 speakers in the front and rear. check out this website http://www.hybrid-audio.com/tradeup__tradein.htm I use hybrid clarus 5.25 gear in my audi and it sounds a lot better than the factory setup. plus, if you have speakers that you are not using, you can trade it in on the purchase of new speakers. hope this helps
