[Elecraft] wiring motorola amplified speaker for K2

[Tim Logan]

I know some of you have used Motorola amplified speakers.....I have one 
and the one thing is not clear. Two of the wires are referred to as 
"audio up" and "audio down". The remaining 3 wires are for power supply 
and squelch......not sure how the two audio wires and "squelch" would 
get connected to a speaker jack for the K2......does this wiring 
resemble anyone's and if so how did you rig up the speaker? Thanks in 
advance.
