SOURCE: My JVC mx-gc5 stereo says protect and then shuts off

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).
