Before installation of the amplifier, first remove the negative terminal from the battery so as not to
cause a short circuit;
Carefully insulate all power connections of wires with a high quality professional electrical insulation
tape;
Do not use electrical insulating tape in places where high temperatures are possible, as it can easily
melt.
Do not open or attempt to repair this unit yourself. There are no user-serviceable parts within the unit.
Refer any repairs to a qualified service technician.
If there is smoke or any weird odor present during use or if there is damage to any of the component
enclosures, immediately unplug the power wire and send the amplifier to your local seller or a
qualified service technician.
TO AVOID DESTRUCTION OR DAMAGE:
Do not connect several negative speaker wires to one and the same negative terminal of the
amplifier;
This line of amplifiers is designed for a voltage of 12V, so check the onboard voltage before
installation;
When leaving the car, it is recommended to always switch off the head unit, otherwise the battery
will be completely discharged.
To avoid risk of electronic shock or damage to the amplifier do not permit any of this equipment to
become damp or wet from water or drinks. If this does occur, immediately unplug the power wires
and send the amplifier to your local seller or a qualified service technician.
TERMINAL WIRED CONNECTION
It is not recommended to connect bare wires to the power terminals, this may cause fire or short
circuit;
It is necessary to periodically check the wire connections to ensure they are securely connected;
Do not twist tangled wires together;
Lay the wires in special insulating tubes;
When laying the wires, make sure that they do not touch moving parts of the car, such as the
gearshift lever, handbrake, seat adjustment lever, etc.
Do not shorten any wires, otherwise the protective system will not work as expected when it is
necessary;
Never supply power to another source by extending a wire from an already connected device. The
nominal resistance may not be enough and the wire overheats, as a result of which a fire may occur;
When replacing a fuse, use only the same rating as recommended by the manufacturer. Using a fuse
with a higher or lower rating can damage the amplifier or may result in fire or electric shock.
Do not connect a loudspeaker with a lower impedance rating than recommended by the
manufacturer of the amplifier. This can damage both the amplifier and the subwoofer;
When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the
amplifier, the audio and power supply cables should, if possible, not be routed along the same side
of the vehicle. It is recommended a separated installation, e.g. routing the power cable through the
cable channel on the left side and the audio cables through the cable channel of the vehicle on the
right side or vice versa. This prevents interferences due to crosstalk into the audio signal.
INPUT VOLTAGE SENSITIVITY ADJUSTMENT FUNCTION
For the first time use turn the GAIN (GAIN of CH1/2 and GAIN of CH3/4) controller of the amplifier to the
MIN position. After it, please, turn the volume controller of the head unit volume to 80 - 90% of its full
setting. Then turn GAIN clockwise until you hear some distortion. Now turn back the GAIN slightly until
you hear a cleaner sound.
