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.

1. Make sure that your vehicle has a 12V DC electrical system with negative grounding. Before installing the ampliﬁer in cars,

trucks or buses, check the battery voltage.

2. Check the state of on-board power supply of your vehicle, the battery and the alternator. When the engine is running,

depending on the ambient temperature, the voltage to be outputted by the alternator must be within the range of 14 to 14.7 V.

Open circuit voltage (OCV) of the battery must be within the range of 12.5 to 13 V. Make sure that the rated current of the

alternator and the battery capacity is enough to provide increased consumption.

For example, for the power of the ampliﬁer 1000 W, the rated current of the alternator is required at the rate of 1000 W / 13 V

= 77 amperes. A more powerful ampliﬁer requires a more powerful alternator as well as an additional battery.

3. Do not place the ampliﬁer in the engine compartment and also in the places exposed to water, moisture, dust or dirt.

4. Never stretch the cables outside of the car and near the moving parts of the car. This can lead to destruction of the

insulating layer, short circuit and ﬁre.

5. The ampliﬁer should be installed in areas of the car where the temperature varies from 0 °C (32 °F) to 55 °C (131 °F). The

ampliﬁer should be in a place with a good air circulation. The horizontal position of the ampliﬁer is the best way to install.

6. During the operation the ampliﬁer may be heated up to 80 °C (176 °F). Before you touch it, make sure it is not overheated

that may be dangerous.

7. To improve the cooling of the ampliﬁer, it is recommended to clean periodically the heatsink from dust. When cleaning the

heatsink strong solvents should not be used as they may damage the ampliﬁer. Do not use compressed air, because solids can

penetrate inside the ampliﬁer. Cleanings best done with wet towels or cloth.

8. Make sure that the location of the ampliﬁer does not violate the proper operation of mechanical and electrical devices of

the vehicle.

9. Make sure that during the installation and connection of the battery, the power cables are not shorted.

10. 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.

11. To protect the wires 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.

12. Make sure that all the cables are ﬁxed over the entire length. Also make sure that their outer protective shell is non-

combustible. Use a clamping screw to secure the positive and negative cables next to the appropriate terminals of the ampliﬁer.

13. Select a diameter of the power cable in accordance with the power of the ampliﬁer and the recommendations provided

here. Power cables are extremely important since they directly aﬀect the system damping factor and sound quality. The cables to

the battery must be in the copper crimp terminals pressed with the help of a hydraulic press, and well ﬁxed to the battery

terminals.

14. To avoid accidental damage, keep the ampliﬁer in its original packaging prior to installation.

15. Use high-quality copper speaker and power cables.

CAUTION!!! High sound pressure can damage your health!

Please use the common sense when controlling volume!

1. INTRODUCTION

2. SAFETY I N S T R U C T I O N S

1. Before installing the ampliﬁer disconnect the battery from the electrical system.

2. To connect the ampliﬁer it is necessary to stretch the power cable from the location of the battery to the place of installation

of the ampliﬁer. Select the power cable with the appropriate regulations in AWG (see Table: Selection of the diameter of the

power cables)

3. Connect the power supply with the correct polarity. Connect all (+) terminals of the ampliﬁer to the cable from the positive

terminal of the battery and the (-) terminals of the ampliﬁer – to the cables running from the negative terminal of the battery.

4. Place the fuse holder for each positive cable within 40 cm from the positive terminal of the battery and connect one end of

the power cable to the holder after connecting the other end to the ampliﬁer. Do not install the fuse.

5. Route all signal cables next to each other and separately from the power cables.

6. Connect the wires of RCA input. The input signal power must be between 0.2 V and 6 V.

7. To connect the power wire supply is necessary to use special power cables.

8. Fasten the ampliﬁer 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. It is not recommended to screw the ampliﬁer directly to the

metal it can lead to distorsions at the signal outputs.

9. After installation is complete, check the wiring of the system and make sure that all connections have been made correctly.

Before installing the fuses, disconnect the positive lead from the battery and then install the fuse in the fuse holder. Using the light

bulb 12 V 21 W, connect the positive lead to one contact of the bulb and the other contact of the bulb to the positive terminal of

the battery.

When properly connected, the bulb must brieﬂy light up and go out. Now you may connect the positive lead to the (+)

battery. If the light does not go out, then something is wrong. This will prevent damage to the ampliﬁer in case of reverse polarity

and unwanted sparks when connecting. Install the rest of the fuses.

10. To activate the ampliﬁer, it is necessary to apply the positive potential of 12 volts to the control input of the ampliﬁer (REM)

through a switch or a corresponding control output (REMOTE OUT) with the head unit (HU).

11. LED indicator on the front panel lights up in green, indicating that the device is turned on. LED indicator lights up in red

when the outputs are overloaded, if the temperature protection is activated, if there is a short circuit in the system cables to the

heatsink and if the ampliﬁer is faulty.

12. The sound level is calibrated by adjusting the volume of the source up to 3/4 of its maximum level. Then, adjust the

sensitivity level of the ampliﬁer up until you hear distortions.

Deaf Bonce ampliﬁers of Machete series are high-quality and technically perfect products. The problems often arise due to

improper use, faulty connection of components or lack of power supply of the on-board network.

1) The ampliﬁer does not turn on.

Problem solution: Check all the contacts and the presence of 9-15 V at the ampliﬁer terminals. Check whether the control input

of the ampliﬁer "REM" receives the positive potential of 12 V.

2) Power turns on, but goes into protection (security indicator lights up)

Problem solution: Check if there is a short circuit (fault) on the ampliﬁer output which is connected to the speakers or

subwoofers. Make sure that commutation of the voice coils of the subwoofer is correct. The rated impedance of the voice coils

should not be lower than the permissible rated load impedance of the ampliﬁer. Check the supply voltage of the ampliﬁer. It must

be within the range of 9-15 V for 15V versions of ampliﬁers.

3) The ampliﬁer turns on but at a high volume it goes to protection. Problem solution: The ampliﬁer may lack power. Make sure

that the rated current of the alternator and the battery capacity is enough to power this ampliﬁer.

Check the ampliﬁer for overheating. Check the load impedance.

4) The ampliﬁer is turned on, but there is no sound from the speakers or subwoofer.

Problem solution: Check the connection of the ampliﬁer, the integrity of the interconnecting cable, HU, the speaker or the

subwoofer.
