Question about Humminbird GPS
had same problem. the cause was corrosion in the boat wiring. the power wire was corroded 95%thru. there was enough voltage to start the unit but when the sounder kicks in the voltage dropped below minimum and the unit shut off. took a LOOOONG time to find.

Take every single cable out of the unit, now power on the unit.
If the power protection still shows then there is an internal fault, usually a short or a component defect.
If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.
Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

SOURCE: power wont stay on
Hope your under warranty mate and if so hope its not in Australia as they cannot fix this problem. My denon was allegedly fixed twice but has now failed a third time (just out of warranty) and denon have turned their back on me.
SHAME ON YOU DENON.
