Check your voltage at your amp.

In situations like these I find it most helpful to remove the amp from the power system it is currently on and bench test it...since you have disconnected everything else. If it works on a bench, you have a problem with the power if it doesn't the amp is having issues

now the question is how do you bench test it?

I have seen it were a bad ground will do this, make sure your ground a good and NOT to a seat bolt or a seat belt bolt.

One thing that bothers me about what you said is that everytime you start your truck the amp turns on in protect ? First of all your amp shouldn't even be coming on until youturn on your head unit or source unit, it shouldn't be turning on off the ignition. If the amplifier turn on (remote on ) is on the ignition you may have damaged the amp over time.
