Thank you for purchasing this ALPHARD product! Alphard Sound Technology is 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.
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 acoustic systems! 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 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.
