Speaker input wire with RCA pin cord
To the RCA input jack of this unit
Notes
!
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.
Solderless terminal
connections
!
Since the wire will become loose over time,
it must be periodically inspected and tigh-
tened as necessary.
!
Do not solder or bind the ends of the
twisted wires.
!
Fasten while making sure to not to clamp
the insulating sheath of the wire.
!
Use the supplied hexagonal wrench to
tighten and loosen the terminal screw of
the amplifier and use it to securely fasten
the wire. Be careful to avoid excessive tigh-
tening of this screw, which may damage
the wire.
Connecting the power terminal
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.
!
Always use the recommended battery and
ground wire, which is sold separately. Con-
nect the battery wire directly to the car bat-
tery positive (
+
) terminal and the ground
wire to the car body.
!
Recommended wires size (AWG: American
Wire Gauge) is as follows. The battery wire,
the ground wire and the optional direct
ground wire must be same size.
!
Use a wire of 8 AWG to 16 AWG wire for the
speaker wire.
