I have a brand new A3 black edition which was fitted with a Symphony II CD Changer. I had this ripped out and an RNSe put in. All fully coded and the Bose wire moved. SOund quality seems pretty flat. I have the Bass and Treble as max and it just seems to lack punch and the highs are just not there. The Mrs has the Symphony head unit and a non BOSE system and it sounds far superior. Any ideas. Someone has said to snip the Bose wire ?
