Connecting the units
Note
! If speaker wires with an RCA pin cord from a
headunit are connected to this amplifier, the
amplifier will automatically turn on when the
headunit is turned on. When the headunit is
turned off, the amplifier turns off automati-
cally. This function may not work with some
headunits. In such cases, please use a sys-
tem remote control wire (sold separately). If
multiple amplifiers are to be connected to-
gether synchronously, connect the head unit
and all amplifiers via the system remote con-
trol wire.
! Connect the system remote control wire when
you wish to only turn on the car stereo, not the
amplifier.
! This amplifier automatically selects an input
signal mode between the RCA level and the
speaker level by detecting an input signal.
Connecting the power
terminal
! The use of a special red battery and ground
wire RD-223, available separately, is recom-
mended. Connect the battery wire directly
to the car battery positive terminal (+) and
the ground wire to the car body.
WARNING
If the battery wire is not securely fixed to the term-
inal using the terminal screws, there is a risk of
overheating, malfunction and injury, including
minor burns.
