Deaf Bonce MACHETE MFA-2.220 | 220 Watt 2-channel amplifier

The Deaf Bonce MACHETE MFA-2.220 is a 2-channel Class D amplifier built for performance-minded car audio installs, delivering substantial power into low-impedance loads and offering flexible bridging options. It outputs 350 W x 2 at 2 Ω (14.4 V) or 220 W x 2 at 4 Ω, with 700 W x 1 in bridge mode, across a 20-20000 Hz range.

• Model: MFA-2.220
• Class: D
• Number of channels: 2
• Frequency response: 20-20000 Hz — covers the full audible spectrum for typical car audio use.
• 2 Ohm RMS Power (14.4 V): 350 W x 2 — supports high-current drivers and demanding loads per channel.
• 4 Ohm RMS Power (14.4 V): 220 W x 2 — balanced power when driving standard 4 Ω speakers.
• 4 Ohm RMS Power (Bridge): 700 W x 1 — bridged mode to drive a sub or mono speaker with substantial authority.
• Minimum permissible load on the channel: 2 Ω — do not run channels below this impedance for reliable performance.
• Minimum permissible load in a bridge connection: 4 Ω — bridged operation requires at least 4 Ω on the load.
• Input SPL: 0.4 - 8V — defines the input voltage range needed to reach full output with typical head units.
• Low pass filter: 50-12000 Hz — tailors bass content to a sub or dedicated woofer, reducing unwanted highs.
• High pass filter: 50-12000 Hz — protects speakers from low-frequency underexcursion and improves midrange clarity.
• LPF and HPF simultaneous operation: True — lets you run both filters at once for precise crossovers across channels or a sub system.
• Crossover: 12 dB/Oct — steepness of the filter slope, aiding clean separation between bands.
• Input terminal: 4 Ga
• Output terminal: 10 Ga
• Working voltage: 9 - 15V
• Signal-to-noise ratio: ��� 90 dB

In a typical car audio build, MFA-2.220 shines as a stereo front-end amp with optional bridged bass, offering flexible crossovers and substantial headroom for high-dynamic content. The 4 GA input and 10 GA output terminals support robust wiring for stable, high-current operation, while the 9–15V working range aligns with standard automotive electrical systems. The combination of wide bandwidth, selectable LPF/HPF, and a 12 dB/Oct crossover lets you tailor the soundstage with precision and minimal distortion across genres.
