This unit is designed for negative ground 12V DC operation only.
Use speakers with an impedance of 4 or 1 Ohms.
Avoid installing the unit where:
- It would be subject to high temperatures, such as from direct sunlight or hot air from
the heater.
- It would be exposed to rain or moisture.
- It would be subject to dust or dirt.
If your car is parked in direct sunlight and there is a considerable rise in temperature
inside the car, allow the unit to cool off before operation.
When installing the unit horizontally, be sure not to cover the heatsink fins with the
floor carpet.
If this unit is placed too close to the car radio, an interference may occur. In this case,
separate the amplifier from the car radio.
if the amplifier malfunctions. Do not attempt to test the protection circuits by covering
the heatsink or connecting improper loads.
Do not use the unit with a weak auto battery as its optimum performance depends on
a normal battery supply voltage.
For safety reasons, keep the volume of your car audio system moderate so that you
can still hear normal traffic sounds outside your car.
PRECAUTIONS
If the fuse blows, check the power connection and replace the fuse. If the fuse blows
again after replacement, there may be an internal malfunction. In this case, consult your
dealer.
WARNING:
Use the specifier amplifier fuse. Use of a higher amplifier fuse may cause serious damage.
PROTECTION CIRCUIT:
This amplifier is provided with a protection circuit which operates in the following cases
when:
the unit is overheated.

POWER CONNECTION
The battery terminal (+12V) must be connected directly to the positive terminal of the
vehicle battery to provide an adequate voltage source and minimize noise. Connecting the
battery terminal lead to any other point (such as the fuse block) will reduce the power output
and may cause noise and distortion. Use only #6 gauge or thicker (smaller gauge #) wire for
this lead and connect it to the terminal of the battery after all other wiring is completed.
GROUND CONNECTION
The ground terminal (GND) connection is also critical to the correct operation of the
amplifier. Use a wire of the same gauge as the power connection (#6 or thicker) and connect
it between the ground terminal(GND) of the amplifier and a metal part of the vehicle close to
the mounting location. This wire should be as short as possible and any paint or rust at the
grounding point should be scraped away to provide a clean metal surface to which the end of
the ground wire can be screwed or bolted.
REMOTE TURN-ON CONNECTION
The amplifier is turned on by ap12V to the remote turn-on terminal (REM). The wire
lead to this terminal should be connected to the "Auto-Antenna" lead from the car stereo
which will provide the +12V only when the car stereo is turned on . If the car stereo does not
provide an Auto-Antenna" lead, the remote turn-on lead may be wired to an "Accessory" or
"Radio" terminal in the car's fuse block. This will turn the amplifier on and off with the ignition
key, regardless of whether the car stereo is on or off. The remote turn-on lead does not carry
large currents. So #20 gauge wire may be used for this application.
SPEAKER CONNECTIONS
Depending on the type and number of speakers used with the amplifier wire them to the
speaker terminals as per the appropriate wiring diagram. For most applications # 10 gauge
wire should be used for the speaker leads . When wiring the speakers, pay careful attention to
the polarity of the terminals on the speakers and make certain they correspond to the polarity
of the corresponding terminals on the amplifier. Do not ground any speaker leads to the
chassis of the vehicle.
INPUT OUTPUT CONNECTIONS
If low -level outputs are provided from the car stereo ,it is recommended that the low-level
inputs be used for lowest distortion and best performance .Use good quality shielded audio
cables with RCA plugs at both ends to connect the stereo to the amplifier and keep the cable
lengths to a minimum to avoid mouse.
The amplifier has : "Line out" RCA JACKS, can be connected with other amplifier.
