Be careful about that -- most amplified loudspeakers have RFI problems.

Remember that the KX3 is specifically designed to be a backpacking rig, 
so everything, including the audio amp, is designed to be stingy about 
using battery power.

One simple thing we can do to maximize the audio output level is to use 
RXEQ to roll off the lower three bands. The sound in these lower bands 
makes no contribution to communications, but it does use power, so when 
we get rid of it, we can use the power for the sound that matters.
