Precautions - Pioneer PREMIER GM-X404 Owner's Manual

To prevent malfunction
• To ensure proper heat dissipation of the
amplifier, take care of the following
during installation.
— Allow adequate space above the
amplifier for proper ventilation.
— Do not cover the amplifier with a floor
mat or carpet.
• Do not install the amplifier near a door
where it may get wet with rain.
• Do not install the amplifier on unstable
places such as the spare tire board.
• The rigidity for installation differs with the
car model and installation location.
Secure the amplifier at a sufficiently rigid
location.
• Make temporary connections first and
check that the amplifier and the system
operate properly.
• After installing the amplifier, confirm that
the spare tire, jack and tools can be taken
out smoothly.
Example of installation on the floor
mat or on the chassis
1.Place the amplifier where it is to be
installed. Insert the supplied tapping
screws (4 × 18 mm) into the screw holes.
Push on the screws with a screwdriver so
they make marks where the installation
holes are to go.
2.Drill 2.5-mm diameter holes at the point
marked, and install the amplifier, either
on the carpet or directly on the chassis.
