I have recently installed an xcarlink in my 2009 A3 with Bose. The issue I am having is that the sound quality is significantly lower than the AUX input or standard CD player. I was expecting a potential drop in quality but not as much as it has, the bass is all over the place and I can't change my settings to find a middle ground, plus I shouldn't have to as the sound quality on all other formats (CD, Radio, AUX) are perfect. Any suggestions would be greatly appreciated, thanks.
