I've got a Sony Xplode, can't remember exact model, and it isn't working correctly. All of my wiring is just fine. It will work for a few minutes and then it goes off and on 2-3 times and then it just goes off. After a while it may come back on and work a few minutes and do the same thing. I do not understand how it could be overheating from just working only a few minutes. What else could it be?
