The amp delivers an equal amount of power to all four speakers all the time. If you only hear sound out of one speaker, there's something wrong inside your cabinet. Are you plugged into one of the 4 ohm stereo jacks or something? Even if you are, you should still hear sound from at least two speakers. With the 8 ohm jack all four should be pumping volume out whether the amp is on 0 or 10.
