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 #12 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 ( #12 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 applying +12V 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#18gauge wire should be used for the speaker leads but in no case
thinner than #20 gauge . For leads is excess of 10 feet # 16 gauge is recommended.
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 CONNECTIONS
This amplifier features both and low-level input capability. Use either the low-level
or high -level inputs, not both.
If the car stereo does not provide low-level outputs, the amplifier may be connected
via the speaker (high-level). Outputs from the stereo. Wire the speaker leads from
the car stereo the 5-pin adaptor harness as shown in the diagram (shielded cables
is not required for this application )and plug the connector into the mating high input
connector on the amplifier. Carefully splice and insulate all wire connection.
WIRING INSTRUCTIONS
Caution: Use either the low-level or the high-level inputs on the amplifier.
Do not use both input levels at the same time.

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 into 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 and6
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
2
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.
HOW TO PROCEED IN CASE OF FAULTS
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 set 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.
