I have a pair of speakers in the cockpit coaming for the AM/FM radio..

I would like to figure out a way to connect the VHF external speaker to
one
of these, so I can hear any calls on it in scan or monitoring of ch16.

Both radios are below deck so I can only hear them in the cockpit on a
remote speaker..

I know I could just use a toggle switch, but would prefer to find a way to
combine both outputs so the VHF would be heard over the AM/FM output.

Is there a simple way to do this and prevent one unit from harming the
other??

Steve-

I'm not exactly sure how it's done, but the aviation headset people (David
Clark in Massachusetts is very helpful) do this sort of thing as a matter of
course, ie a CD player works through the headset but radio transmissions
will override it. The principle is the same- I know the DC people will help
if you can't find an answer elsewhere. Or try the crowd at
rec.aviation.piloting
