My radio was turning off by iteself over and over did it more often when i turned the volume up, so i bought a new headunit and it is doing the same. someone screwed what i am almost positive is the antenna wire and if the antenna wire isnt plugged in the radio it doesnt turn on at all. I tried repairing the wire jimmy rigging it and the radio is able to go higher in volume and stay longer but still turns off when i get it up higher in volume. Could this be just that antenna wire or something else, what are your thoughts? thanks.btw i checked the speakers wires and they look good.
