Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Using an ohm meter to the sub will confirm whether its bad or not. Invest in a cheap test set of 6.5" speakers.
.A thumbs up would be greatly appreciated if this answer is helpful to you.

It sounds like the problem is simply that you are requesting too much power from your amp. Make sure that you know what your subwoofers are requesting from the amp. It is probably too much for it too handle. You need to figure out first the total impedance the combined subs are requesting considering the wiring setup you have, then see how much power the amp puts out at that impedance. Then figure out how much power is reaching each individual subwoofer.

are you absolutely certain your subs are in good shape? have you put a meter on them and measured the ohms as you depress the cone [causing the cone to move up and down on the pole of the magnet? do the ohms stay constant? go up to infinity[ suggesting an open] or go to zero or close to zero [ suggestting a short] both of these conditions will result in a zero or a very limited output from your amplifier, while still showing a green status light, if or when a full short or open occurs on the subs, a fault led will become lit, and whet that means is that u have fried the outputs....do a bit more testing with your vom....and good luck or try another speaker for testing purposes...

Bad or shorted voice coil on sub maybe. If you have two subs try them one at a time to see if it goes into protect mode. Whatever sub does it is bad.

It is very dependent on your vehicle and whether you are using the built-in amp of the head unit or a separate amp. Ideally, I would recommend a good 6.5" component set.
