Hey guys, I'm considering upgrading the speakers on my 2002 A3, I'm currently running everything stock other than the fact that I changed the standard 'Audi Chorus' radio for an after-market system so that I can use SD-cards and Aux-in to run my iPod through. Whilst I'm really pleased with the radio I feel the standard speaker system is lacking bass. I'm not interested in a 'chavvy sub-woofer to wake the dead and is three times the size of my boot' system but I would like to improve the sound quality I get in my car. Where you guys recommend I start? is it an easy fix to fit the premium Bose speakers to my car? forgive my lack of knowledge in regards to this in advance, I really have very clue as to what I'm talking about when it comes to upgrading sound systems...
