Are you sure both switches are turned on? On the Port side, as you walk down the steps, there are 4 switches. 2 for lights and right under that 2 for stereo. They allow you to turn the speakers on or off up top and below.

The switches go to the blue wires connected to the amps. They send the signal to turn them on/off. Consider reversing the blue wires to the two amps to see if you have a loose connection with the blue wires between the stereo head unit and the amps. If so, no many how many amps you replace, the problem will still exist.

Since the amp turns off an on, this is where I'd start. Also, look into the amp's power source and ground.
