Iv got this problem with my amp dub1002 for my 6x9z. the thing is you see it was working for a couple of months until i realised that the red lights come up you see when it should be green could you possibly tell me what could have caused this could it be the remote cable.

Disconnect all the wires except the three main power wires, ground, 12v battery and remote. Now, turn on your radio, if the protect light is still on then there's an internal short in the amp. If the light turns green, then there's a short in either the auxiliary cables or the speaker outs. If it turns green, then troubleshoot the other wires that plug into the amp by connecting them one at a time until the protect light comes on, which will tell you that there's a problem with that speaker/aux wire.
Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.
To test if the amp even turns on take the amp and three wires (does not matter what guage) and connect it straight to the battery. Two wires (one for the power and the other one to the remote) and the third wire goes to ground. This will verify that the amp does in fact work. If this test fails then something has happened to the amp. If the test passes and you see that you do have power to the amp with this test then you know that you have a wire issue. Trace out your wires and make sure that you have a good connection throughout the car. This should fix the problem
If the amps are going into protect mode, it's likely that the output transistors have failed in both amps. This can be due to many things. Generally it's caused by running the amps at too low of an ohm load. If you drive the amps hard on a daily basis, that can also cause the amps to fail prematurely.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is too low.
