I'm about to close up the front of my "9" and there is a pair of
wires coming from the Icom A200 for an external speaker. Should I
terminate them with a resistor or just leave them open. I do not intend
to utilize a speaker in the cockpit.

Good for you. Refer to the instruction manual. If they
don't call out a dummy load, you can just leave it open.
Actually, the few radios I've see that called for a dummy
load on unused outputs would probably have been quit
stable without it.
The only think I can think of that would prompt a designer
to require loading an unused input is to accommodate
an output stage instability under light loads. Modern
audio amplifier ships don't have this problem.

You can safely leave the dummy load resistor out.
