NOTES ON THE POWER SUPPLY:
Connect the +12V power input lead only after all other leads have been
connected.
Be sure to connect the ground wire of the unit securely to a metal part of the car.
A lose connection may cause a malfunction of the amplifier.
REM: The unit is turned on by ap12 Volts to this terminal. This terminal
does not draw heavy current like the tow Power Terminals so a thinner connecting
wire is acceptable. Standard 18 GAUGE is fine and the standard color is yellow. If
the radio is equipped with a Power Antenna control wire, it can drive this terminal.
If the Power Antenna wire is already in use, you can still splice into it. With this
method, the unit will turn on automatically with the radio.
Use the power supply lead with a fuse attached whose value is the same as original
fuse.
Place the fuse in the power supply lead as close as possible to the car battery.
During a full power operation, Maximum current will run through the system.
Therefore, make sure that the leads to be connected to the +12V and GND
terminals of the unit respectively must be at least 10-Gauge (AWG.10).

After the amplifier has been installed and all connections have been made carefully
and securely, turn the radio on so that the amplifier is switched on automatically.
After a short power-on period, the amplifier reaches its full performance.
Now turn up the volume slowly using the volume control of the radio. If there is no
sound or only a distorted replay, switch off the radio immediately - the amplifier will
also switch off automatically - and check if all connections have been made correctly.
GAIN = INPUT LEVEL CONTROL
The input level control allows the system to work well within a wide range of
output level. Choose the adjustment in the way that you achieve a sound most
possibly without any distortion. As a guideline the following procedure is
recommended:
If you use several amplifiers, the adjustment has to be made for each set separately.
Tune in the volume of your car radio to 2/3 of the maximum volume. Now turn the
gain control of the amplifier from "Min" to "Max" direction until you can hear
distortions. Then turn the level control a little back to "Min". The gain control
adjustment is finished now.
Attention! If you use 2 Ohm speakers in stereo mode. Tri-mode or 4 Ohm
speakers in bridge mode and the overload protection is triggered out, turn the gain
control to "Min" direction, until the operation is free of trouble.
X-OVER FREQUENCY CONTROL
A). When the crossover control is in the Low-Pass position, this control becomes
active allowing you to select your crossover point. For example: If you select 50Hz
the amplifier will operate below 50Hz, If you select 250Hz the amplifier will
operate below 250Hz.
B). When the crossover control is in the High-Pass position, this control becomes
active allowing you to select your crossover point. For example: If you select
120Hz the amplifier will operate above 120Hz, If you select 3KHz the amplifier
will operate above 3KHz.
CROSSOVER SWITCH
Flat: full range frequency.
Low pass: the lower frequency under setting point can be pass.
High pass: the higher frequency above setting point can be pass.
BASS BOOST CONTROLS
This amplifier has Bass controls for making good sound combination.
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 any claim for warranty is denied.
