7 wires are present on the DB-25 connector and hook up as follows:
Pin 2 ------ Black --- 12VDC -
Pin 3 ------ Brown -- 12VDC -
Pin 5 ------ Green -- 12VDC+
Pin 11 ---- Red ----- 12VDC+
Pin 20 ---- White --- Audio IN
Pin 21 ---- Blue ----- Audio IN
Pin 24 ---- Orange --12VDC+
The Motorola spec sheet/schematic confirms the presence of a current limiting resistor for the Squelch (Pin 5 Green), so 12VDC+ works fine. You could hook the green lead to switched power, which would turn the internal amplifier in the speaker on & off accordingly.
In it's designed use with the Convertacom, the vehicle unit provided a +DC voltage to the amplified speaker's green (squelch) lead so it would automatically turn the speaker amplifier on & off based on audio breaking squelch. So if you can find a +DC voltage in your radio that is present when squelch is broken, or perhaps only when the radio is on, (supplying same to the speaker's green lead) it'd be a power saver feature and the internal amp in the speaker wouldn't be on all the time.
Absolutely the best way to go. It's designed specifically for voice communications. If you crank up the volume it will blow you right out of the car!JnglMassiv said:Go big or go home!
Motorola NSN6054A 12 watt amplified speaker. Requires minor modification for use with scanners.
Hint: there're several on ebay right now.

That's funny.I love the faces of the kids in thier ricers when we go grocery shopping on Friday night, they pull up thumping, We tell the kiddo to cover his ears, and give them one track from my test CD.
