Shaker 500 "Audio Bleed" Issue in 2012 GT
I have a 2012 Mustang GT with Shaker 500 audio system and I noticed, what I'll call "Audio Bleed" issue. If I'm listening to an FM station and switch to USB or XM (and it's quiet), I can still hear the FM station faintly. When I increase the volume, it doesn't increase with the regular audio so it can be drowned out, but I know it's there. If I shut-off the radio and then the car while it's on USB or XM and then turn them all back on, the FM sound is not there. It's as though once the channel is active there's some cross-over between the analog paths inside the stereo. I saw several references to this from 2007 to 2009 on another forum, but couldn't find anything here. Maybe I'm not looking in the right place, so any help would be appreciated. I just want to get some feedback before bringing it to a dealer. Thanks!
