Unless of course it was just the amp's thermal limit circuit cutting in.

No, I don't think that is it. From an earlier post...

Pulling the unit out of the dash to reboot it will fix it, but only for a few minutes. However, putting the Empeg in front of a vent blasting cold air will fix it for half an hour or so

I don't think rebooting or cooling down the empeg is going to help the amplifier much.

Well... maybe. The amplifier will be powered off when the empeg is pulled from the dash. Perhaps just the 15 seconds or so it takes to reboot will allow the amplifier to cool enough to reset the thermal limit circuit. Seems unlikely, though...
