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.
