Before installing the amplifier
! 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
! Do not install in:
Places where it could injure the driver or
passengers if the vehicle stops suddenly.
Places where it may interfere 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
! 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.
! 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
! Protection function may activate to protect the
amplifier against overheating due to installa-
tion in locations where sufficient heat cannot
be dissipated, continuous use under high-vo-
lume conditions, etc. In such cases, the am-
plifier reduces the power output or shuts
down until it has cooled to a certain desig-
! 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
! After installing the amplifier, confirm that the
spare tire, jack and tools can be easily re-
Example of installation on
the floor mat or chassis
Place the amplifier in the desired instal-
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.
Drill 2.5 mm (1/8 in.) diameter holes at
the imprints either on the carpet or directly
on the chassis.
Install the amplifier with the use of
supplied tapping screws (4 mm × 18 mm
(1/8 in. × 3/4 in.)).
