Need help?Do you have a question about the Deaf Bonce ML-10A and is the answer not in the manual?
This document is an owner's manual for the Deaf Bonce Machete Lite series active subwoofers, specifically models ML-10A and ML-12A.
The Deaf Bonce Machete Lite active subwoofers are designed to provide extremely loud sound systems without compromising quality. These units integrate a subwoofer and an amplifier into a single enclosure, making them a convenient solution for adding powerful bass to a vehicle's audio system. The manual provides instructions for proper installation, operation, and maintenance to ensure optimal performance and longevity.
The Machete Lite series includes two models: ML-10A and ML-12A.

Both models feature a low pass filter (LPF) adjustable from 30 Hz to 280 Hz at 12 dB/Oct, allowing users to tailor the subwoofer's frequency response. The input signal level adjustment (GAIN) ranges from 0.85 V to 4 V. The amplifier section includes terminals for power supply (+12V, GND), remote activation (REM IN), RCA signal input (INPUT), and a high-level signal input terminal (HIGH LEVEL INPUT). A dedicated input for a bass remote control is also present. Operation is indicated by a blue POWER LED, while a red LED signals protection mode.

The manual outlines a standard wiring diagram for connecting the active subwoofer to a car battery and head unit. This involves connecting the positive power cable to the battery's (+) terminal and the amplifier's +12V terminal, ensuring it's protected by an appropriate fuse. The negative power cable connects the battery's (-) terminal to the amplifier's GND terminals. A remote turn-on cable connects the head unit's Remote output to the amplifier's REM IN terminal. Finally, RCA cables connect the head unit's RCA outputs to the amplifier's RCA inputs. High-level input is also available for head units without RCA outputs.
Proper settings are crucial for optimal performance and longevity. The manual recommends warming up the subwoofer's moving parts for 40 hours at medium power using musical material. During this break-in period, or if a strange smell is detected at maximum volume, the volume should be lowered to allow the device to cool. Recommended amplifier settings include keeping the head unit volume below 80% and setting the amplifier sensitivity (GAIN) to 50%. The low pass filter (LPF) should be set between 63-80 Hz to cut frequencies above this range, preventing overheating and voice coil damage.
The manual also includes a table for selecting the appropriate speaker cable diameter based on cable length and power consumption, ensuring efficient power delivery and preventing voltage drop.
The manual emphasizes several safety instructions that also contribute to the maintenance and longevity of the device:
The product comes with a warranty against defects in materials and manufacturing under normal functioning conditions. Defective parts will be repaired or replaced at the manufacturer's discretion. For warranty claims, the product must be returned to the dealer with a properly filled warranty certificate and original packaging. Repairs outside the warranty period will be at the customer's expense. The manufacturer disclaims liability for transportation damages, loss of profit, or other incidental costs.
For European countries with separate waste collection, the manual provides information on the disposal of electrical and electronic equipment. Products marked with a "crisscrossed wheeled bin" symbol should not be disposed of with regular household waste but in special reception centers equipped for recycling. This practice helps protect the environment and prevent harmful health effects.
