Measuring an unknown input impedance is easily done. I have a little box (with a variable resistor) I constructed many years ago to accomplish this. :)
http://www.sengpielaudio.com/calculator-InputOutputImpedance.htmThe power amplifier output impedance is irrelevant since it will be a small fraction of the speaker load.
Cheers,
Dave.
