OPERATION

GND(-)=GROUND CONNECTION
Connect the GND terminal to the chassis ground of your car and take care of best
electric and mechanic contact. In doing so, drill a hole in to the    car  chassis near 
the amplifier then remove color, dirt or any other substance from the ground point.
After that fasten the cable end with added ring terminal by using a screw.   Ensure
that the ground connection is as short as possible and that the cable  diameter   is 
sufficient  ( min 4 mm" ). Route the ground     cables  from the  radio  and  all other
equipment parts. like equalizer. active    crossover network or other amplifiers,  to 
the same ground point.
+12V=POWER SUPPLY
Connect the +12V terminal  to   the positive pole of the battery with     a lead cable 
and add a fuse in to the power cable in a distance of not more then 30 cm from the 
battery.     The lead cables's diameter should be at least  4 mm' for a length of  3m 
and 6 mm" for a length of 6m.
REM(ON/OFF)REMOTE CONTROL 
Connect the REM terminal to the automatic antenna connector of your   car  radio.
Now when turning on and off your car radio. the amplifier automatically   switches
ON and OFF. A cable diameter of 0.5mm   is sufficient.
FUSE
The amplifier is equipped with a plug-in auto fuse protecting the set against  fault 
conditions. Do not use a fuse with a higher value and never bridge  the  fuse over, 
as this may lead to  irreparability damage  so  that ant any  claim  for    warranty is 
denied.

No Function:
The connection cable is not connected correctly (  = terminal  BATT/GND   /REM).
Ensure that  all  connections and mechanic contact and that  the jacket has  been
removed.   The fuse is defective-pay  attention to the correct  value of a new fuse!
No Sound:
Speaker cable or speaker plug are not connected correctly.
No Sound /Red LED Protection Shines:
The plus and minus  wires  of the speaker cable have contact,  thus eliminate  the
short circuit. If you use    a  2 Ohm speaker in stereo mode,  a  4 Ohm   speaker  in
bridge mode or   tri-mode and  the se is  overloaded, then turn the  gain control to 
"min " until the operation is free of trouble.
Poor Sound Quality ( Distortions ):
The speakers are overloaded,   therefore  turn  down  the volume level and check
the volume control positions.
No Stereo Sound And A Weak Bass:
Speaker cables (+) and (-) are mixed up, unit wired out of phase.   
   

TROUBLE SHOOTING

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.
