when does the light come on? while playing songs, at the time you turn on the stereo? what kinda amp you have
did you check all your connections?
is the nosie non-stop? you check the connections for your speakers?

If you have a mutimeter check the resistance of your subs(in parallel). If its close to zero then you may have a shorted voice coil. If you don't have a multimeter there's a couple of other ways to check your subs. You could try disconnecting each sub one at a time or hook up a flashlight battery to each and see if the cones move.

However, the first thing I'd try is disconnecting both subs at the amp and see if it still goes into protect mode when you turn on your system. If it does its most likely a problem with the amp.
