Got a Kicker DX350 hooked to a single CVR 12" sub. It's been fine for about 4 years now. Settings are about midway, the amp is nowhere near maxed out, no problems until lately.

Now, anytime I turn the volume up even a little bit the amp cuts off for about 5 seconds, then will come back on for a few seconds until it cuts off again. The green "OK" light on the amp is on.

What do you think? Time for a new amp?
