I have c220 w204. Jsut had an amp installed and when I turn the stereo on, the majority of the time I get speaker popping for a couple of seconds and I constantly get alternator whine,. The other day I was driving the stereo turned itself off and back on 3 times within about 20 seconds then 5 mins later it done i once again. It seems to do this atleast once a day, does anybody have any advice on how to fix the stereo issue is would taking out the fuse for it and leaving car off for a while help any, IV heard that's how to reset the radio. Thanks
