[Elecraft] Motorola Amplified Speakers ...

Sat Aug 10 15:12:00 2002

Success at last!  While this info wasn't exactly for my
speaker it got me there.  The key was the green wire. I
don't have a yellow wire but if I connect the Red, Orange, 
and Green wire to +13.8v and connect the Brown, and Black 
wires to GND, and bring in the audio on the White wire it
works great.  I have a Blue wire left over that I don't have
a clue as to it's purpose.  I did attenuate the audo input
by a facctor of two as I could just barely turn up the volume
from minimum before it was too loud.  It does seem to work
as advertised and looks nice too.  Thanks to all who helped
provide this information.
