The actual power output you get will depend on the supply voltage and speaker impedance.

PWM, (Pulse Width Modulation) is the most efficient way to control analog circuits using digital outputs, by changing the duration and frequency of the signal.

This circuit is made for a DIY builder, I left enough room for a heat sink. for the filter capacitor.

This a simple circuit, very easy to build and also efficient. There is enough space for mounting a heat sink, you may want to use a IRFZ44N instead.
