!
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.

Route battery wire from engine com-
partment to the vehicle interior.
!
When drilling a cable pass-hole into the ve-
hicle body and routing a battery wire thor-
ough it, take care not to short-circuit the
wire damaging it by the cut edges or burrs
of the hole.
After completing all other amplifier connec-
tions, finally connect the battery wire terminal
of the amplifier to the positive (
+
) battery
terminal.
