    Do you mean how much power? You could use a multimeter, measure the voltage of a constant sine wave on the outputs, and estimate the impedance of the driver (4 ohms, 6 ohms, 8 ohms, whatever). Then use the equation Power = Voltage^2/Impedance and figure it out. Its not exactly right, but its quick, and you'll get a decent idea of what the power output is.

    To properly measure the output power, you would need an oscilloscope to make sure the sine wave was not clipping, yet it was at the maximum before clipping. No point in figuring out the power if you're only getting half of the power output.
