CAUTION

Example of installation on the floor

• Do not install in:

such as on the floor in front of the driver's

seat.

• Make sure that wires are not caught in the sliding

mechanism of the seats, resulting in a short-cir-

cuit.

• Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier.

Protect all cables and important equipment such

as fuel lines, brake lines and electrical wiring

from damage.

• Install tapping screws in such a way that the

screw tip does not touch any wire. This is impor-

tant to prevent wires from being cut by vibration

of the car, which can result in fire.

located.

To prevent malfunction

• To ensure proper heat dissipation of the amplifier,

be sure 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.

• Do not install the amplifier on unstable places

such as the spare tire board.

• The best location 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 easily removed.
