SAFETY INSTRUCTIONS

1. Fasten the speakers properly when installing them in the vehicle. If the component is disconnected during driving, it may cause serious damage to the passengers of the vehicle or another vehicle.
2. Before installing the components, if possible store the product in its original package to avoid accidental damage to the product.
3. Be careful when installing or dismantling the speaker! Do not let the speaker drop to avoid damage to 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 speaker does not hinder the proper operation of the 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 °C (41F) to +40 °C (104F). In case of moisture condensation, let the product dry.
8. When performing plumbing, drilling or cutting works with the car, make sure that there is no wiring, brake lines, fuel pipe, or other structural elements under the place of work. Follow the safety rules! Use protective glasses and gloves.
9. When stretching back 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 under the length and applied power.
11. Never stretch the cables outside of the car and near the moving parts of the car. This can lead to the 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.

CAUTION!!! High sound pressure can damage your health! Please use common sense when controlling the volume!

Use the table below to select the desired diameter based on the length and the power consumption.

FILTERING, RECOMMENDED AMPLIFIER SETTINGS

• The correct choice of amplifier, its settings, filtering, and enclosure largely influence 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) with the amplifier will allow clean, undistorted signals applied to the component to prevent overheating and voice coil damage.
• Recommended settings of the amplifier and HU: HU volume should not exceed 80%. The amplifier sensitivity should be set to 50%.

The recommended filter settings:

• The high pass filter HPF (the filter that cuts all frequencies below those set for the filter) should be set to 150-250 Hz (24 dB/Oct), or 250-350 Hz (12 dB/Oct)
• The low pass filter LPF (the filter that cuts all frequencies above those set for the filter) should be set to 8-10 kHz (12 dB/Oct)
• Recommended amplifiers: MLA-60.2, MLA-100.2, MLA-160.2, MLA-60.4, MLA-100.4, MLA-160.4.
