If speaker input wires from a headunit are con-
nected to this amplifier, the amplifier will automa-
tically turn on when the headunit is turned on.
When the headunit is turned off, the amplifier
turns off automatically. This function may not
work with some headunits. In such cases, make
sure that the Left channel is connected correctly.
If the function still does not work, please use a
system remote control wire (sold separately). If
multiple amplifiers are to be connected together
synchronously, connect the head unit and all am-
plifiers via the system remote control wire.

wire RD-223 (sold separately) is recom-
mended. Connect the battery wire directly to
the car battery positive terminal + and the

inal using the terminal screws, there is a risk of
overheating, malfunction and injury, including
Route battery wire from engine com-
partment to the vehicle interior.
! When drilling a cable pass-hole into the ve-
hicle body and routing a battery wire thor-
ough it, take care not to short-circuit the
wire damaging it by the cut edges or burrs
of the hole.
After completing all other amplifier connec-
tions, finally connect the battery wire terminal
