Alright guys... I've got my new car on order to arrive in November and i'm looking into the system i want to fit when it arrives. I think i know roughly what HU i want (double din Pioneer or Kenwood multimedia with sat nav) but it's the amp and speakers which are causing me a headache... The car is an Audi TT-S and i'm trying to find out what size the stock speakers are....with little luck. Does the TT have the same set up as all other Audi models? If so, what size are the stock speakers and tweeters?? Any advice would be much appreciated! Paul.
