I have a Clarion AM/FM/CD, ( in the boat ), Not sure of the model #, 515 audio pro, I think. Problem is if I turn the volume up over 18, the unit acts like it has a circuit breaker built in. It will play for a few seconds, then it shuts down for a second or two, then come back on.
Can anyone explain what's going on? And what can I do about it?
Thanks!!!

from my experience that is a low volt condition, can you put a DVM on the power leads going into the stereo and make sure the
Voltage does not drop below 10. volts , I found this same condition on many boats and cars either installed with wrong wire sizes or just a bad connection.
Its still possible that its some power or amp chip problem inside the stereo.

Both these guys have real likely sollutions. First I would put a ohm meter over the speaker terms and test them (you have to disconnect the wires to do this. If they all test ok then I would check for voltage drops (this is what my money is on) but you still should fallow test procedures

It's all those damn blinking lights you're running with the stereo..

Thanks for the info guys!! I will do some more investigating.
Steve, The blinking lights wil not stay inthe boat.........
