Default amp problem

i have a boss dd3600 amp about a couple of days ago i noticed while i was listening to music the amp would cut off and go to protection mode and then go back to normal untill yesterday it just stayed in protection mode i checked the speaker wires they werent making any contact i checked the power,ground and remote wires they werent makin any contact at all i checked all the fuses none of them are burned out at all also i didnt get the smell of like burned at all but somehow when i connect a subwoofer on it it the subwoofer just moves.

so can anyone give me suggestions or help on how to fix this amp? i have a video uploaded so you can see the problem that im having better heres the link below..

It likely has shorted output transistors.

It can likely be repaired. Can you post a good quality photo of the inside of the amp?

yes, that looks like shorting in the ouput sections, likely one, or more transistors. the pulsing should be from the amps protection trying to keep it from shorting out the power supply section, and cooking the sub. don't hook the sub back up, or it can slowly cook the coil
