Hi all, This is my first proper post in the audi-sport forums - I just became the proud owner of a new A4 TFSI S-Line Special Edition. The car has BOSE fitted - I ordered it as an option because my previous BMW had the Harman Kardon upgrade, which sounded fantastic. However I'm *REALLY* disappointed with the BOSE system -especially since it cost so much as an option. The system appears to have very weedy bass output, even with the bass slider set to really high. When I fade the speakers to the front or back the sound quality is all midrange and treble with very little bass. I've checked what I assume is the sub (located in the rear parcel shelf) and it is putting out some bass noise, but it just doesn't make itself felt, especially when sat in the front. Now, I'm not some huge-pumpin-bass-crazed youth, but I do like a quality sound system. Is there something wrong with my system d'you think or is it just a case of "they all do that, sir"? Are there any settings I might have missed? (I've got the Symphony Head Unit, if that makes any difference..!) Help!?
