1. INTRODUCTION

Thank you for purchasing this Deaf Bonce product of Machete series! Our company is committed to the creation of extremely high-profile 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's in this manual. Please keep the manual in a safe and accessible place for future reference.

2. SAFETY INSTRUCTIONS

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.

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

3. WIRING DIAGRAMS

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.

5. HOW TO USE

The correct choice of the amplifier, its settings and 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 operation. Be extra careful when warming up the parts. Warm up the subwoofer using musical material for 40 hours on medium power. If, during operation at maximum volume you feel strange smell, you should make the volume of the subwoofer low and cool the device down at a low volume.

Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier sensitivity is 50%, subsonic filter frequency (Subsonic) is 5 Hz below the port settings. For example, if you configure the port at 30 Hz, Subsonic is should be 25 Hz. The low pass filter LPF (the filter that cuts all frequencies above those set for the filter) 63-80 Hz, bassboost to 0.
