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.

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 prote ction circuit to protect the transistors
and speakers 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 tra ffic sounds outside your car.
