Here it is…radio worked fine on sat. Get to the dock and shut all electronics off as the wife retrieves the truck. As I’m sitting there, motor idling, a loud screech like fingernails on a chalkboard comes out of my speakers?? At first thout I was dock rashing the fiberglass!! 
What the heII…turned the main radio power on/off and the noise went away. A few seconds later, same thing. The power was off at the console when this happened…the radio was not powered up. It was late…1am so I didn’t mess with it till today. Power on, all buttons, display works, but no sound from either speaker. I checked all fuse’s, wiring, plugs, pulled the speakers and they look fine. Everything is working as it should but no sound. What about that screech? Is my stereo fried?
