For improved speaker output a single transistor audio amp will be a great improvement. So what are our options? The maximum output to a 8Ω speaker can be calculated using the Ohms Law formula P = V * I, or in this case P = 5v * 300ma = 1.5w. It is desirable for Vout to be 1/2 of V+ to drive the transistor in the middle of its operating range.
