The KPA/100 has the capability built in.  If you want to use the K2 to 
drive it, there is a circuit someone(s)  here on the list created, along 
with a circuit board, that plugs into the K2 on a header in the back of the 
radio, and Keys an amp just fine.

As far as the power output, 10 watts is the most you can depend on from the 
K2 barefoot.  While you can squeeze a bit more out, you do it at the 
expense of distortion.  the KPA/100 takes you up to where you can drive it 
comfortably, and also run 100 watts if that is all you need.

I don't know if anyone on the list has a commander, but I know there are 
many Alphas on here being run by K2s.
