That is a fault in your wiring. When you turn it up, the wattage increases on your speaker terminals. Once it gets loud enough, it sparks across terminals, causing it to shut off.

Look at your speaker connections. Make sure each one is clean, and that there isn't even a single strand of wire that gets close to another speaker terminal. That is the cause of that error.

Unless there is internal damage that will require a shop, you'll find the problem at the speaker connections. These can be random, and occur at any time, so it's important to be thorough while you're reconnecting the speakers. Do one at a time so you don't mix up which speakers plug into which terminal.
