I had my car inspected & for the last week or so my stereo/electrical system in the car has went "haywire." There's a loud cracking-snapping like frequency noise that suddenly will emit when the stereo is turned on at times & sometimes even when its off. all fuses r okay. Obviously its something in the electrical system & it usually disables all audio for a time but the noise remains happening at random & wasnt there prior to inspection. I live 40 mins away from the Ford dealer so wanted to see if anyone knew wtf was happening here b4 calling them or had any advice on a fix. I have audio of the noise but wasnt sure if u can upload on here or not. thanks in advance.
