SOURCE: problem with amp...
In virtually all instances where the protection light is illuminated, the amplifier has gone into protection because the output transistors are shorted. To eliminate external wiring problems do the following.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.
If it does have blown outputs, it's is likely due to the speaker wires shorting together when the woofer was out of the vehicle.

SOURCE: wiring up amp/installing amp
Disconnect all the wires and make sure that their all connected to the right terminals. If not positively sure trace all wires back to source. If you ground and power is swapped it will automatically go over to protection mode.

SOURCE: kole amp in protect mode?
Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.
Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.
Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.
