wiring the amplifier
Step #1: With amplifier in place, take the yellow/black wires on the input
connector of the amplifier and plug them into the front factory speaker
wires on the clutch side of the bike. They will only go in one way. Take
the brown/black wires on the “front out” connector and plug them into
the front clutch side speaker. They will only go in one way.
Step #2: Take the green/black wires on the input connector and plug them into
the front factory speaker wires on the brake side of the bike. Take the
blue/black on the front out plug and plug them into the brake side front
speaker. Again, these will only go on one way. The orange wire is the
“remote turn on lead” and tells the amp to turn on whenever it sees
+12v (.5 amp min.). Unplug the center wire (+) on the cigarette lighter.
Plug the orange lead from the amplifier directly onto the lighter using
the female connector. Plug the factory lighter wire to the male “take off”
connector which is part of the amps orange turn on lead.
