as suggested it sounds like rca inputs are seeing chassis ground... check the RCAs connections and make sure the RCA casing isn't contacting ground inside your dash.... also make sure deck ground is solid... try swapping RCAs if necassary....

Sometimes when you have the gain way up the amp starts picking up the most minute signals, that could be it.

The amp is protected. But
Doesnt go away. I disconnected the RCA's and the Speakers wires still no go.

If i disconnect the RCA's and the Speakers wire are Connected they pulse ands it still says protected.

I saw an amp do that when the owner busted the RCA terminals, so it grounded them out to the chassis. Could be repairable.

this problem is most commonly found using earthquake amps. known as the "earthquake rumble". common symptoms are your subs rumbling once your amp turn on and there is no music playing. cures are finding a different amp, aswell as cracking your amp in half over your head!
