Connecting the Unit
Using the Speaker Input
Connect the car stereo speaker output wires to the amplifier using the supplied speaker input wire with RCA pin cord.
• Slide the input switch to the right.

•As a result of connecting the car stereo speaker output wire to the amplifier, the power of the amplifier is turned on automatically when the car stereo is turned on. It is not necessary to connect the system remote control wire in this case.
Note:
•Connect the system remote control wire when the power of the amplifier is not to be turned on when the car stereo is turned on.

Installation
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
•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.
•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.
Replacing the terminal cover
1.Align the unit and terminal cover, and insert the screw.
2.Tighten the screw with a 4 mm or 5/32 inch hexagonal wrench (not
supplied).

*Average current drawn
•The average current drawn is nearly the maximum current drawn by this unit when an audio signal is input. Use this value when working out total current drawn by multiple power amplifiers.
