The output of the top amplifier feeds the negative input of the bottom amplifier so their output voltage swings are doubled. With a +/-12V power supply The top amplifier output swings to a peak of +9V when the output of the bottom amplifier swings to a peak of -9V. Then the 8 ohm speaker gets 20W RMS just before clipping. When the supply is +/-16V and the distortion is very high then the output is 34W.
