Check ur power wiring ie. make sure it's not shorting to ground anywhere. Also check if it's got a fuse in the end of the amp and see whether or not that's blown
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 .

Sometimes i goes into protection when the amp is overloading with power.. Or the amp is touching metal.. Or the ground wire aint in the right place..Or check your RCA's, Speaker wires? if their earthing your amp..
It could be even simpler than that, yes an improper impedance rating on an amp will cause it to overheat, but should function temporarily until it reaches peak temp. If the outputs were blown the protect light should not light up being that they would need to work to cause the protect light to come on. I would double check all of your connections, one small little crossed wire would cause an amp to immediately go into a protect mode.
If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.
Sounds like there could be a short somewhere. Check to make sure that there aren't any (exposed/bare) wires touching each other or if there is a bare spot of wire touching something metal. Check both ends of all the wires. A speaker wire may have come lose and is shorting out against the frame or some other place. Usually if it goes straight into protection mode or you're popping fuses you have a short somewhere. I assume the capacitor you installed is somewhere on the power line, which would be for helping with noise. You can also try disconnecting your amp from your stereo and see what happens but leave the speakers connected, you don't want to run the amp with out a load on it (the speakers). If your amp doesn't go into protection mode when the stereo is disconnected, then you have a problem with the stereo and not the amp, assuming you already checked for any possible shorts first.
