I was gone most of the weekend and when i returned home i went to turn on the stereo but I guess my mom unplugged it. I didnt know why until later on my stereo was turning on and off over and over, everytime i plugged it in. i thought that was the extent of it but when i left the room the stereo not only turned on by itself but the volume raised to the highest volume i could hear across the house and then it became muted and turned off. i dont know what to do please help me is it a short,are the wires crossed if so what do i do to fix it?
