CAUTION
• 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
•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.
•DO NOT allow amplifier to come into contact with liquids due to, for example, the location where the amplifier is installed. Electrical shock could result. Also, amplifier and speaker damage, smoke, and overheating could result from contact with liquids. In addition, the amplifier surface and the surface of any attached speakers could become hot to the touch and minor burns could result.
•To ensure proper installation, use the supplied parts in the manner specified. If any parts other than the supplied ones are used, they may damage internal parts of the amplifier, or they may become loose causing the amplifier to shut down.
•Never replace the fuse with one of greater value or rating than the original fuse. Use of an improp- er fuse could result in overheating and smoke and could cause damage to the product and injury including burns.
CAUTION:
To prevent malfunction and/or injury
•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.
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 be located.
2.Drill 2.5 mm (1/8 inch) diameter holes at the point marked, and install the amplifier, either on the carpet or directly to the chassis.

*Average current drawn
•To ensure proper heat dissipation of the amplifier, be sure of the following during installation.
•DO NOT allow amplifier to come into contact with liquids due to, for example, the location where the amplifier is installed. Electrical shock could result. Also, amplifier and speaker damage, smoke, and overheating could result from contact with liquids. In addition, the amplifier surface and the surface of any attached speakers could become hot to the touch and minor burns could result.
