1. INTRODUTION
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.
2. SAFETY MEASURES
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 occupants of the car or another vehicle.
2. Before installing the components, if possible store the product in the package in order to avoid inadvertent 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 instruments observe safety precautions.
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 violate 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 feeding 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 secured and protected over the entire length.
10. The cross section of the speaker cables must be selected with respect to the length and applied power.
11. Never feed back 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 inflammation.
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.
Attention! High sound pressure can damage your health. Please be responsible and practice safe sound.
3. CONNECTION METHODS
You must 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.
