The problem is that the driver circuit is also damaged. Try powering up the unit with the output transistors disconnected. Measure each pad and report the results here. You should see something like 0.6,B+,0.0 on each set of three. Some will be negative rather than + (-0.6,B-, 0.0).
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. Your amp is clipping.
No internal fuses. Your mosfets are toast.

Nice amplifier. However it is best suited for speakers and not for sub woofers.
Connect the plus (+) from speaker output 1 and the minus (-) from speaker output 2.
Connect the plus (+) from speaker output 3 and the minus (-) from speaker output 4.
Now the amplifier is in bridge mode, which will give you 300 WATT RMS at 4 OHM load.
If you are bridging the amplifier to run sub woofers then do not forget to set the X- Over to LPF on the channels that you are planning to bridge. Whatever you do, make sure that the load you are asking the amplifier to play is no lower than 4 OHM. Playing this amplifier in bridged mode lower than 4 OHM is a recipe for trouble.
You are probably presenting too low an impedance load to the amplifier. In bridged mode the amp must be connected to a minimum 4-ohm load. If your subwoofer is a dual voice coil type with 4-ohm voice coils, you cannot wire the voice coils in parallel and connect it to the bridged amplifier. If you have a sub with dual 2-ohm voice coils, you can wire the voice coils in series and connect it to the amplifier in bridged mode.
To connect voice coils in series: Connect a wire from the negative terminal of one coil to the positive terminal on the other coil. Connect the unused positive and negative terminals to the amplifier's output.
If I were a guessing man, I'd guess that you had your amp hooked up in a bridged configuration. And also that you connected your two speakers in parallel (plus to plus and minus to minus). And if I were to further guess, I'd guess that you have a blown amp now because of what I mentioned above. Sounds like you need to spend some quality time with your favorite electronic repair shop. Good luck.
Sounds like you have overloaded your amp. When you bridge you MUST make sure that you still have the proper speaker load. One 4 ohm speaker on one channel is fine, but when you bridge that same 4 ohm speaker, it gives you a 2 ohm load on each of the two channels that are now bridged. If you made the mistake of wiring two 4 ohm speakers in parallel (plus to plus and minus to minus) then when you bridge you will be driving a one ohm load on each channel. This is very close to a dead short. Stop using your amp at once until you get your speaker load correct. This will damage your amp and it will cause you to have to go to a repair shop to fix it. DO NOT RUN YOUR AMP ANYMORE UNTIL YOU FIX THIS. Good luck.
