INSTRUCTIONS FOR POWER
Before installing and using this unit,
Read the instructions carefully
Make sure you have chosen the right place to connect the device. The location must be completely dry, with
good air circulation and securely fastened.
Proper connection of the system is the best way to maximize the performance of your amplifier. Proper
installation - is the reliability of your system.
A WARNING
system connection
Each channel of the amplifier can easily operate with a
4 ohms speaker impedance when used in stereo. The
recommended minimum load on the 2nd channel
a subwoofer and 4 ohms for the full operation of the
speakers. Using a connection with low impedance will
not lead to immediate damage to the internal circuitry,
the unit is likely to overheat, resulting in a thermal
protector, power turns off. When the housing has
cooled down, normal operation resumes. Continue
operation of the amplifier is not suitable under those
conditions, because the duration of its life is reduced
due to such operation.
Most of the speakers,
intended for car audio, have a resistance of 4 ohms
(the impedance). Connecting two such speakers will
result in parallel to the load 2 Ohm. Some subwoofer
models have a double coil with an impedance of 4
ohms. The combination of these voice coils in parallel
will lead to resistance to 2 ohms, which is
recommended for use only in the bridge connected to
your amplifier.
Connecting the speakers:
Serial connection
parallel connection
A series-parallel connection
- 1 -
Power supply + 12V feeding only after all wires are connected. Required securely connect the grounding
wire to the metallic device of the vehicle.
Misalignment can lead to failure of the amplifier. REMOTE (control wire): The amplifier is energized
when the +12 volt terminal. Standard wire has 18Ga section and its standard color: blue. If the head unit
is equipped with an additional power antenna, it can also control this terminal. If the antenna wire is
already in use, you can connect to it. With this method, power is automatically turned on when the head
unit is switched on.
Use wire power (+ 12V) only fuse, the fuse rating chosen according to the cross section of the wire.
Fuse set as close as possible to the car battery (within 30cm from the plug).
Ensure that the wires connected to the terminals of the amplifier 12B + and GND, wire section must
be 10Ga (AWG 10) or more than: 8, 4, 2, 0 Ga.

Trouble-shooting
malfunction
not included
distorted sound
Amplifier on and off
REMOTE (control wire) is not connected or
there is no signal
blown fuse
power cable "+" or "-" is not connected
Crossover is not set
wheezing speaker
Output power is too large
Too low impedance for the amplifier
Thermal protection, amplifier temperature is
greater than 90 degrees
Short circuit
Ensure that the control wire + 12V
Check the fuse on the battery and on the
amplifier (replace blown)
Check the integrity of cables, make sure
that there is ground
Adjust the crossover according to the
instructions
Check the operation of the speaker, in
case of breakage replace desktop
Turn down the volume
Check the dynamics of resistance if below 2
Ohm, use a serial connection
Make sure that sufficient
ventilation
Check the wiring for short-circuit
