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 term-
inal.

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
100 A.
2 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.

Before installing the amplifier
WARNING
! To ensure proper installation, use the supplied
parts in the manner specified. If any parts
other than those supplied are used, they may
damage internal parts of the amplifier, or be-
come loose causing the amplifier to shut
down.
! Do not install in:
— Places where it could injure the driver or
passengers if the vehicle stops suddenly.
— Places where it may inter fere with the dri-
ver, such as on the floor in front of the dri-
ver’s seat.
! Install tapping screws in such a way that the
screw tip does not touch any wire. This is im-
portant to prevent wires from being cut by vi-
bration of the car, which can result in fire.
! Make sure that wires do not get caught in the
sliding mechanism of the seats or touch the
legs of a person in the vehicle as short-circuit
may result.
! When drilling to install the amplifier, always
confirm no parts are behind the panel and
protect all cables and important equipment
(e.g. fuel/brake lines, wiring) from damage.
CAUTION
! To ensure proper heat dissipation of the ampli-
fier, ensure the following during installation:
— Allow adequate space above the amplifier
for proper ventilation.
— Do not cover the amplifier with a floor mat
or carpet.
! Place all cables away from hot places, such
as near the heater outlet.
! The optimal installation location differs de-
pending on the car model. Secure the ampli-
fier at a sufficiently rigid location.
! Check all connections and systems before
final installation.
! After installing the amplifier, confirm that the
spare tire, jack and tools can be easily re-
moved.

Connecting the units Installation
Attaching the Bass boost
remote control
Attach with tapping screws (3 mm × 10 mm
(1/8 in. × 3/8 in.)) at an easily accessible loca-
tion such as under the dashboard.
Tapping screws (3 mm × 10 mm (1/8 in. × 3/8 in.))
Example of installation on
the floor mat or chassis
1 Place the amplifier in the desired instal-
lation location.
Insert the supplied tapping screws (4 mm ×
18 mm (1/8 in. × 3/4 in.)) into the screw holes
and push on the screws with a screwdriver so
they make an imprint where the installation
holes are to be located.
2 Drill 2.5 mm (1/8 in.) diameter holes at
the imprints either on the carpet or directly
on the chassis.
3 Install the amplifier with the use of
supplied tapping screws (4 mm × 18 mm
(1/8 in. × 3/4 in.)).
