Connecting the Unit
Connecting the Power Terminal
• Always use the special red battery and ground
wire ([RD-223] and [RD-222]), which are sold
separately. Connect the battery wire directly to
the car battery positive terminal (+) and the
ground wire to the car body. There is the risk of a
fuse burning out if only one of these is connected.
1. Pass the battery wire from the
engine compartment to the interior
of the vehicle.
• After making all other connections to the
amplifier, connect the battery wire terminal
of the amplifier to the positive (+) terminal of
the battery.

and system remote control wire.
3. Attach lugs to wire ends. Lugs not
supplied.
• Use pliers, etc., to crimp lugs to wires.
4. Connect the wires to the terminal.
• Fix the wires securely with the terminal
screws.
WARNING
Failure to securely fasten the battery wire to the ter-
minal using the terminal screws could cause the ter-
minal area to overheat and could result in damage
and injury including minor burns.
