I am having what sounds like a bad or lose connection eminating through all the speakers. Almost like it it picking up external interference like sometimes happens when a truck passes you on the highway. There is no rythm to the occurance, just sparatic. It happens with the car not running or moving and just the key in acc mode. Its also happens running and moving. And the volume of the distortion is very loud even with the radio volume at minimum. All features of the radio work fine and it still sounds great even when the intermittent distortions or static happens. Anyone ever run into this problem? Thanks in advance for any suggestions
