PRECAUTIONS
FUSE REPLACEMENT
If the fuse blows, check the power connection and replace the f use. If the fuse
blows again after replacement, there may be an internal malfunction. In this case,
consult your dealer.
WARNING:
Use the specified amperage fuse. Use of a higher amperage 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.
the speaker terminals are short circuited.
This unit is designed for negative ground 12V DC operation only.
Use speakers with an impedance of 2 or 4 Ohms (
2 to 4 Ohm when used as
bridging amplifier
)
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.
This power amplifier employs a protection circuit to protect the transistors and
speakers if the amplifier m lfunctions. 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.

These are driven by the line output of your in dash radio or
intermediate signal processor, Separate Left and Right signals can be applied for
Stereo or Mono operation but both inputs must be driven with the same signal for
proper Bridged operation .lf only mono signal is available ,a " Y" adapter is required .
