· NEVER operate the amplifier without the proper power and ground wire 10 gauge minimum. · NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will blow instead of the wire burning up. Using other than the recommended fuse ratings at the battery and at the amplifier may cause damage to the amplifier and will void your warranty.
Installation MOUNTING: 1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1. 2. Once the location has been determined, remove the plastic decorative panels from left and right sides of amplifier then place the amplifier in position. Using a felt tip pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as a template for drilling. It is very easy to damage the amplifier surface in manner. 3.
Connections POWER SUPPLY AND REMOTE TURN-ON OF THE AMPLIFIER NOTE: Do not connect the plus terminals to the car battery before other connections, or it may occur short circuit. The gauges of power cables should be enough for the power amplifier demands at least 5.27mm2. The + 12V DC and ground cables should be at least 6mm2. Firstly connect the GROUND terminal to the battery negative pole. It is very important that the connection is fastened.
Operation elements and in / outputs SETTING THE INPUT AND SENSITIVITY The regulator for input sensitivity is used to adapt amplifier for each car radio or tape deck. Turn the volume control of your radio to central position and adjust the input-level control (3) Fig. 5, to produce medium volume. This setting can provide sufficient power and optimum Signal to Noise (S/N) ratio. CAUTION: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be damaged.

An on/off switch should be inserted in this case. Make sure that this switch is turned off if the amplifier is not used. Fig.
FIG. 2 STEREO MODE Connect and set the amplifier as shown in Fig. 2, when the stereo has two outputs and the unit is used to drive two loudspeakers. The high-pass filter must be activated if the amplifier drives satellite loudspeakers. See section HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY to catch how to regulate the high pass filter.
