Deaf Bonce MACHETE MFA-1.500 | 500 Watt Power Amplifier

The Deaf Bonce MACHETE MFA-1.500 is a single-channel Class D amplifier delivering 500 W RMS at 1 Ω, built for demanding subwoofer duty in high-performance car setups. Its compact 6.3 x 6 x 2.1 inch enclosure and 9-15 V operating range suit tight installs in typical automotive electrical environments.

• RMS Power (1 Ohm, 14.4 V): 500 W — High current capability for low-impedance sub loads, delivering strong bass dynamics.
• RMS Power (2 Ohm, 14.4 V): 360 W — Robust output with moderate impedance subs or parallel configurations.
• RMS Power (4 Ohm, 14.4 V): 210 W — Efficient power delivery at higher impedance for steady bass.
• Minimum permissible load on the channel: 1 Ohm — Enables driving very low-impedance subs for maximum headroom.
• Frequency response: 10 - 250 Hz — Focuses on the bass range for targeted sub optimization.
• Low pass filter: 50-250 Hz — Keeps bass content within a defined range to reduce muddiness.
• Subsonic filter: 10 - 55 Hz — Protects against ultra-low frequencies that can cause distortion or speaker damage.
• Crossover: 24 dB/Oct — Steeper roll-off helps cleanly separate bass from midrange content.
• Input terminal: 4 Ga — Indicates a sturdy signal path for the input connection.
• Output terminal: 8 Ga — Supports robust current delivery to the subwoofer.

In a real car audio build, this amp serves as a dedicated subwoofer channel capable of maximizing bass output from 1 Ω loads while offering precise control with a dedicated subsonic and low-pass network. The 24 dB/Oct crossover and 10-55 Hz subsonic filter help protect the sub and maintain clean, punchy bass, and the compact enclosure simplifies installation in tight trunks or behind dashboards. The 160 dB signal-to-noise ratio supports clean bass at higher listening levels, and the 6.3 x 6 x 2.1 inch footprint allows flexible placement anywhere in the vehicle.
