Dear Customer!
Thank you for purchasing our product. For safety, it is strongly recommended
to read this manual carefully before connecting, operating and/or adjusting
the product and keep the manual for reference in future.
Description
Important safeguards
- This manual contains important instructions for use and care. Please read this manual before using the device and keep it for future reference.
- Do not hit the device or drop it.
- Do not expose the device to vibration, direct sunlight, high or low temperatures or humidity. Do not turn on the device in bathrooms, near kitchen stoves, heating equipment.
- Do not dismantle the body of the device yourself. Have the device repaired only by qualified personnel. There are bare high voltage wires in the device. The voltage inside the appliance is high enough to cause electric shock.
- Prolonged exposure to sound pressure levels in excess of 100 dB can cause permanent hearing loss. High power car audio systems can generate sound pressure levels well above 130 dB, use common sense and sound hygiene.
- Do not install the amplifier in a place subject to direct sunlight or moisture. Be sure to install the amplifier on a solid, hard surface that will not deform under load in the event of a sudden stop of the vehicle or an accident.
- When mounting the amplifier on a side wall, try to position it so that the slots in the cooling fins are vertical. The amplifier should not be mounted on the bottom of the rear deck panel with the fins down, as this will radiate heat back into the amplifier. Leave enough space on either side of the amplifier to make all the wiring and set up the controls. If your car has a subwoofer box, you can install the amplifier outside the box.
CAUTION: when mounting the amplifier on the bottom of the car, make sure that the screws do not pierce the brake or fuel line.
Installation
- Because the amplifier is sensitive to electrical and motor noise, and interference from the amplifier can affect radio reception, try to install it at least 1 meter away from the receiver. Good spots include under the seat, in the trunk or around the sunroof.
- The amplifier is a high power device that generates a large amount of electricity and heat. Therefore, be sure to install the device in a place with sufficient airflow, a minimum of dust and moisture. Leave enough space around the cooling fins to ensure adequate airflow and cooling. It is important to ensure that the heat sink’s cooling fins do not touch a panel or surface that obstructs air circulation.
Electric connection
-
IMPORTANT: before making any connections, disconnect the car battery until installation is complete to avoid possible damage to the electrical system.
-
The +12V DC power cable must be heavy gauge stranded copper cable with thick insulation as it draws its power directly from the positive battery terminal. Choose a cable with a cross section of at least 10 mm2. The cross section of the earth cable must be the same as that of the power cable.
-
Connect the +12V power
terminal to the battery (+) terminal. The +12 V power cable must have a built- in fuse close to the battery at a distance of less than 50 mm. If there is no fuse, an accidental short circuit may result in fire and damage to the amplifier. Connect the fuse holder to the battery, but do not install the fuse at this stage. -
Connect the ground
terminal directly to the negative (-) battery terminal or to the vehicle chassis. Make sure that all paint or other insulation is removed from the connection, and use a self-tapping screw to securely attach the bare ends of the wires to the vehicle chassis. Wires should be as short as possible. -
Many car radios and other sources have an output jack for connecting an amplifier remote control. Connect the output jack to the REM remote control jack.
If the radio does not have a remote turn on function, you can connect the REM jack to an external switch to turn the power on/off of the amplifier. -
To minimize interference, it is best to route the power cables in the opposite direction from the audio cables.
ATTENTION: Power cables must be connected tightly. A poor connection may result in malfunction, interference, or distortion.
Other connections
Input connections
• This amplifier is equipped with RCA connectors for low level inputs. The low level signal is transmitted over RCA cables. It is preferable to use the amplifier’s low-level inputs if the head unit (radio) is equipped with low- level outputs.
Speaker output connections
- You do not need to set up the amplifier input connection before connecting the speaker outputs.
- Connect the right and left speaker wires to the corresponding speaker output terminals on the amplifier.
- Make sure the positive wire from the speaker is connected to the positive terminal of the amplifier and the negative wire to the negative terminal. Reversing either of these connections will move the speaker cones out of phase, resulting in bass suppression.
Volume control
First, set the volume
control on the amplifier to min. After turning on the radio for the first
time, set the volume control of the radio to about 80% of full power. Start
playing the sound and slowly turn up the volume of the amp until you hear
distortion, then turn the volume down for a cleaner sound.
