all! I have an Audi 8P A3 Black Ed 1.8T. Concert as standard and full bose! Now, the bose system worked great. Good bass. But i needed a better HU! So, I purchased Sony XAV-1000 I’m all connected, speakers are working. However 1) I have the whine noise. I believe this is due to bad earthing, so I’ve ordered ground loop connectors. Will this do the job? Or is there anything else? 2) my main concern is i feel like I’ve lost bass...my speakers don’t sound the same. How can i change this? Will the RCA Ground Loop isolators make the speakers clear again? Any help will be much appreciated!!
