Protection turn on and off repeatedly

Hey guys, i recently purchased a Pioneer Gm-D8604 and plugged it into my car.

When I used the speaker level input the protection turns on and off constantly resulting in one of the speakers popping out and back in.

I unplugged everything except the ground and power and tried using the remote wire. Same exact thing happened, protection light goes red, then blue, and back again.

Does anybody know if my amp is busted or a way to fix this issue?
