Ive got a 1999 A3 TDI sport, with the standard audi stereo system. 2 x front door speakers & tweeters. 2 x rear door speakers. 1 x audi sub in boot. Ive had a Sony MP3 XPLOD unit installed, but the trouble is, the audi speakers aint up to much anymore, and are **** at handling bass! I just wondered if anyone had upgraded there whole speaker system in their car and which speakers would be recommended? Ive only got about a £500 budget for which id ideally like... 2 x Replacement front door speakers 2 x 6 x 9's in an accoustic parcel shelf 1 x Sub 1 x Amp (will just bypass the rear door speakers) Plus someone to fit it all! Can anyone give me a general price for what i should be paying And if anyone could recommend any good places in Leeds to get it fitted?
