Check the voltage at the amp. It's possible that the voltage is either too high (above 16V) or too low (below 8.5V). Also make sure that the amp case is not grounded. If these check out OK, the most likely cause is that the amp itself is defective and requires service.
Hope this helps.

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.
