Modified the schematic with a parallel output stage. Any help with wattage calculation? Not sure where i should be measuring the voltage from.

RMS you have a little less than 2.18A current at 4Ohm. Result I²*R=P= 2.18A*4Ohm=8.7Watt

With a standard RMS calculation using P=IV (voltage from Vout given as 12.4V peak, 8.76Vrms), I was getting ~19 watts RMS.

I was more concerned with calculating the power dissipation of the resistors, which i now know as P=I²R.
