1. INTRODUCTION
Thank you for purchasing this AVATAR product, which committed to the creation of extremely high-profile systems with no
loss of quality.
To ensure proper use, please read through this manual before using this product. It is especially important that you read and
observe CAUTION’s in this manual. Please keep the manual in a safe and accessible place for future reference.
2. SAFETY INSTRUCTIONS
1. Fasten the audio system properly when installing it in the vehicle. If the component is disconnected during driving, it may
cause serious damage to the passengers of the car or another vehicle.
2. Before installing the components, if possible store the product in the package passengers of the car to avoid accidental
damage.
3. Be careful when installing and dismantling the speaker systems! Do not let the speaker drop to avoid damage of its moving
parts.
4. When working with tools follow safety rules.
5. Before the installation switch off the head unit and all other audio devices to avoid their damage.
6. Make sure that the location of the audio system does not hinder the proper operation of mechanical and electrical devices
of the vehicle.
7. Do not install components in places exposed to water, excessive humidity, high or low temperature, dust or dirt.
ATTENTION!!! The product may be operated at +5 to +40 °C. In case of moisture condensation, allow the product to dry.
8. When drilling or cutting out holes in the body of the car, make sure that there are no cables or any other important
construction elements under a selected area or inside it.
9. When stretching the speaker cables make sure that they are not in contact with sharp edges or moving mechanical devices.
Make sure that they are firmly fixed and protected over the entire length.
10. The diameter of the speaker cables must be selected in accordance with the length and applied power.
11. Never stretch the cables outside the car and near the moving parts of the car. This can lead to destruction of the insulating
layer, short circuit and fire.
12. To protect the cables use rubber gaskets if the wire passes through a hole in the plate, or other similar materials if it lies
close to the parts exposed to heat.
13. Possible commutation versions are presented on the following pages. Using the data from the table below, check the
minimum resistance of your amplifier specified by the manufacturer.
CAUTION!!! High sound pressure can damage your health!
Please use the common sense when controlling volume!

3. WIRING DIAGRAMS
Possible commutation versions are presented on the following pages. Using the data from the
diagram below, check the minimum resistance and the connection specified by the manufacturer.
Do not expose the amplifier to loads below the predetermined value.
Use these formulas to calculate the resistance of different connection types.

4. FILTERING, RECOMMENDED AMPLIFIER SETTINGS.
The correct choice of amplifier settings, filtering and enclosure largely influence on the lifespan of your audio
system. You should select an amplifier with a nominal power, not exceeding the nominal power of the speakers.
Proper coordination of the head unit (HU) of the amplifier will allow to get a clean, undistorted signal applied to
the component to prevent overheating and voice coil damage. The recommended HU volume is not more than
80%, input sensitivity of the amplifier is 50%.
The recommended filter settings:
The high pass filter HPF (a Filter that cuts off all frequencies below the frequency setting of the filter)
is about 80-100 Hz (24 dB/Oct), or 250-350 Hz (12 dB/Oct)
The low pass filter LPF (a Filter that cuts off all frequencies above the frequency of the filter) - 4-8
kHz (12 dB/Oct).
Recommended amplifiers: AST-2.250, AST-4.250, AST-3004
