Hi, I've just taken the bose amp out of my car due to a crackling front speaker. Thanks to AndyMac I understand that re-soldering some of it may stop the crackling, but does anyone know which joins? I'm reluctant to do all of them due to my relatively little experience! Bottom middle of image is where the connector is... I have also read that in the A4 B6 there is a connector near the doors which may become corroded and affect speaker performance, does anyone know if this is the same case for 8L A/S3's? Any help would be apprecaited becuase this is driving me insane!
