Whenever a little bass sound - explosions, gunfire, helicopter blades, etc., ''PROTECTOR'' flashes on LED and shuts down receiver. Seems to happen more frequently lately. Subwoofer cable sturdy, no fraying. 1 Speaker wire goes under house, but when i disconnect that speaker, it still happens.

The protection feature on these units will shut off the receiver when there is too much power draw or when a speaker wire is touching another wire. First, check all of your speaker connections and make sure the wires are nicely twisted and inserted into the speaker and receiver with no stray wires touching. Secondly, if this doesn't correct the problem, try going into your speaker settings menu on your receiver and select "small" for each speaker. Let your sub handle the bass. The sub cable should have no effect on the protection feature of the receiver. The speaker wires, however, are the most common culprit of a receiver turning off (protector). Hope this helps.
