Deaf Bonce Machete MLA-500.1 XS | 500 Watt Power Amplifier

Deaf Bonce Machete MLA-500.1 XS is a 1-channel Class D amplifier delivering 500 W RMS at 1 Ohm, built for serious subwoofer duty in compact car audio installs.

• Class: D — High-efficiency switching design minimizes heat and power draw, helping you keep a tight install without excessive cooling needs.
• Number of channels: 1 — Mono channel dedicated to a subwoofer, optimizing control and output for bass reproductions.
• 1 Ohm RMS Power (14.4 V): 500 W — Maximum output at a 1 Ohm load, enabling strong bass slam with suitable subwoofers and enclosures.
• 2 Ohm RMS Power (14.4 V): 360 W — Reduced impedance still delivers substantial bass power, useful for different subwoofer configurations.
• 4 Ohm RMS Power (14.4 V): 200 W — Higher impedance yields lower current draw, offering flexible wiring options in some installs.
• Minimum permissible load on the channel: 1 Ohm — The amplifier is stable down to 1 Ohm, supporting aggressive subwoofer wiring setups.
• Frequency response: 10 - 250 Hz — Covers sub-bass up to the lower mid-bass range, shaping the depth and impact of bass.
• Low pass filter: 50 - 250 Hz, 12 dB/Oct — Fine-tune the upper cutoff of the bass to match enclosure and subwoofer tuning with a steep, controlled roll-off.
• Subsonic filter: 10 - 50 Hz — Protects the woofer from ultra-low frequencies that can cause excessive cone excursion or inefficiency.
• Input terminal: 4 Ga — Power wiring input supports a robust connection for high-current operation.
• Output terminal: 8 Ga — Speaker wiring output designed for solid connectivity to the subwoofer.
• Working voltage: 9 - 15 V — Compatible with typical automotive electrical systems, with headroom for voltage variations in the vehicle.
• Signal-to-noise ratio: ≈ 100 dB — Low noise floor helps preserve bass clarity, especially at higher listening levels.
• Size (WxLxH): 6 x 3.2 x 1.4 inch — Compact footprint facilitates flexible mounting in tight trunk, under-seat, or dash-area installations.

In a real car audio build, the MLA-500.1 XS powers a dedicated subwoofer channel with ample headroom while remaining thermally efficient. Its 1 Ohm capability and precise filtering help you tailor bass to the enclosure and listening space, all within a compact chassis and robust wiring scheme for reliable performance.
