1. Fasten the subwoofer 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 in order to avoid accidental damage.

3. Be careful when installing and dismantling the subwoofer! Do not let the subwoofer 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 subwoofer 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 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 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.

You should connect both voice coils!

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 various types of compounds.

The minimum permissible resistance at the output of the ampliﬁer is 1 ohm. Use these formulas to calculate the

resistance of various types of compounds.
