Connecting the power terminal
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
! 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
Battery wire and ground wire size
less than 2.2 m (7 ft
less than 3.6 m (11 ft
less than 6.4 m (20 ft
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
1 Positive (+) terminal
2 Battery wire (sold separately)
The maximum length of the wire between
the fuse and the positive + terminal of the
battery is 30 cm (12 in.).
3 Fuse (100 A) (sold separately)
Each amplifier must be separately fused at
Use wire cutters or a utility knife to
strip the end of the battery wire, ground
wire and system remote control wire to ex-
pose about 10 mm (3/8 in.) of the end of
each of the wires, and then twist the ex-
posed ends of the wires.
Connect the wires to the terminal.
