INTRODUCTION
Thank you for purchasing of this Deaf Bonce product! Our company is committed to the creation of extremely loud sound systems with no loss of quality. To ensure proper use, please carefully read through this manual before using this product. It is especially important that you read and observe caution in this manual. Please keep the manual in a safe and accessible place for future reference.
SAFETY INSTRUCTIONS
- 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 vehicle or another vehicle.
- Before installing the components, if possible store the product in its original package to avoid accidental damage to the product.
- Be careful when installing and dismantling the subwoofer! Do not let the subwoofer drop to avoid damage of its moving parts.
- When working with tools follow safety rules.
- Before the installation switch off the head unit and all other audio devices to avoid their damage.
- Make sure that the location of the subwoofer does not hinder the proper operation of mechanical and electrical devices of the vehicle.
- 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 (41 F) to +40 °C (104F). In case of moisture condensation, let the product to dry.
- 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.
- 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.
- The diameter of the speaker cables must be selected in accordance with the length and applied power.
- 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 circuits and fire.
- 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 volume!
WIRING DIAGRAMS
Attention! You need to connect both voice coils of the subwoofer. Do not expose your amplifier to loads below the value predetermined by the manufacturer. Various examples of connection types are given at the pages below. Use these examples to determine the required load impedance of your connection.
Connection of terminals
Serial connection
Total impedance = ΩSub 1 + ΩSub 2 + ΩSub 3 …
Parallel connection

HOW TO USE
The correct choice of the amplifier, its settings, and enclosure design prolong
the lifetime of your subwoofer. You should select an amplifier with a nominal
power below the nominal power of the subwoofer. Proper coordination of the
head unit (HU) with the amplifier will provide a clean, undistorted signal fed
to the subwoofer, which prevents overheating and voice coil damage. Like any
other speaker, the subwoofer has moving and stationary parts. We strongly
recommend that the moving parts of the subwoofer should be warmed up at the
beginning of the operation. Be extra careful when warming up the parts. Warm
up the subwoofer using musical material for 40 hours at medium power. If you
feel a strange smell during operation at maximum volume, you should lower the
volume of the subwoofer and let the device to cool down at a low volume.
Recommended settings of the amplifier and HU: The volume of HU should not
exceed 80%. The amplifier sensitivity should be set to 50%, subsonic filter
frequency (Subsonic) should be set to 5 Hz below the port settings. For
example, if you configure the port at 30 Hz, Subsonic should be set to 25 Hz.
The low pass filter LPF (the filter that cuts all frequencies above those set
for the filter) should be set to 63-80 Hz, bass boost should be set to 0.
