The problem I am having is that when the car is started there is a high-pitched constant buzz that can be heard, it is not extremely loud but can easily be heard. It started fairly randomly and I had thought it was my head unit until recently when I had it was replaced and the sound was still there. The sound does not start if the car is only turned on to the first start position so just the stereo is running but will sound if 2nd position is switched on although the car doesn’t need to be running. I was told to check my rear speaker connections but can't see any problems there. Any information or help would be greatly appreciated. Thanks.
