It's likely the amplifier but defective speakers or having speaker wires shorted to ground can cause strange problems also (depending on the way the protection circuit responds).
Disconnect the speakers from the amp and connect a speaker that you know is in good working order. Use a speaker that can handle a lot of power and be ready to switch the amp off quickly or disconnect the speaker wires from the amp in case the problem is in the amplifier (you don't want to damage the test speaker).
