If an amp's spec says it has a maximum of 5W power at 32 Ohms , how can we figure out the maximum output power at a different impedance  say, at 600 ohm ?
 
I am guessing it cannot be determined ?

do I have to look at the amp's maximum voltage output ?
 
Guess I figured it out.... I use the max output voltage then choose my impedance find I using the Ohm's law then P=I*V
 
 
Am I correct ?

You can't do that reliably. Some amps are better at low impedance output. Some at higher impedance.
