I have 3 wet sounds amps in my boat. One of them is continually restarting right after it finished its power up cycle. It blinks 7 times, has solid blue light for about 2 seconds, then turns off. A few seconds later it does it again, over and over and over. The other 2 amps are working just fine. I have checked fuses, voltage, current, unplugged the inputs and outputs. Nothing I do seems to help. I'm worried the amp is shot. Has anyone seen this or know of anything I can try to do to resolve it?
