! 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.
Battery wire and ground wire size
Wire length Wire size
less than 4.5 m (14 ft.9 in.) 8 AWG
less than 7.2 m (23 ft.7 in.) 6 AWG
less than 11.4 m (37ft. 5 in.) 4 AWG
1 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.
