Either blown subs, or bad amp.. Disconnect the subs, and try turning the amp on, if the amp is still in protect then your amp is bad, if the protect light goes off, then your subs are bad, or possibly wired at to low of an impedance, but I don't think that will trigger the protect on an Audiobahn amp.
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 . Please check speakers impedance .A thumbs up would be greatly appreciated if this answer is helpful to you
