Did you test it with no speakers? When an amp is in protect mode, it usually means something inside failed. On occasion it is something as simple as wire strands shorting between terminals. Do a visual inspection of it all (including interior) to see if you find something obvious.

Where’d you pick that amp up?

Pull it and test it at the battery post. Simple Power up test to verify if it powers up fine out of protect mode. if it does then Id be checking Ohm load of subs and all wire secured, from supply wiring to ground wiring and connections, damaged inline fuse as well.
