Notes
If speaker input wires 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 automatically. This
function may not work with some headunits.
In such cases, please use a system remote
control wire (sold separately). If multiple am-
plifiers are to be connected together synchro-
nously, connect the head unit and all
amplifiers via the system remote control 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.
