Deaf Bonce MACHETE MFA-2.420 | 420 Watt 2-channel amplifier

Deaf Bonce MACHETE MFA-2.420 is a compact two-channel Class D amplifier built for serious car-audio builds, delivering up to 630 W per channel at 2 Ω, 420 W per channel at 4 Ω, and 1260 W when bridged into 4 Ω, with a full-range 20–20,000 Hz response.

• Class: D — Efficient power delivery in a compact package, well-suited for under-seat or trunk mounting without excessive heat buildup.
• Number of channels: 2 — Provides two independent channels for a front stage or a bridged single-channel sub setup.
• Frequency response: 20–20,000 Hz — Covers the full audible spectrum for accurate music reproduction across most passenger-car material.
• 2 Ohm RMS Power (14.4 V): 630 W × 2 — Higher voltage swing into low-impedance loads for louder, punchier output on compatible speakers.
• 4 Ohm RMS Power (14.4 V): 420 W × 2 — Balanced two-channel performance for standard 4 Ω speakers with solid headroom.
• 4 Ohm RMS Power (Bridge): 1260 W × 1 — High-power bridged configuration ideal for driving a subwoofer from a single channel.
• Minimum permissible load on the channel: 2 Ohm — Defines the lowest stable impedance per channel for safe operation.
• Minimum permissible load in a bridge connection: 4 Ohm — Ensures bridged operation remains within design limits when driving a sub.
• Input SPL: 0.4–8 V — Specifies the input voltage range the amplifier expects for proper level matching with head units or processors.
• Low pass filter: 50–12,000 Hz — Lets you tailor the amp’s output to a sub or full-range setup by cutting higher frequencies.
• High pass filter: 50–12,000 Hz — Enables removing subsonic content or shaping the upper bass/low-midrange transfer for speakers.
• LPF and HPF simultaneous operation: True — Both filters can operate at the same time for precise multi-speaker crossovers.
• Crossover: 12 dB/Oct — A moderate slope that maintains musicality while reducing off-axis leakage and distortion at crossover points.
• Input terminal: 4 Ga — Thicker-gauge input wiring supports robust signal transfer from high-output head units or processors.
• Output terminal: 10 Ga — Heavy-gauge output wiring capable of handling high current to low-impedance loads.
• Working voltage: 9–15 V — Optimized for typical automotive electrical systems, accommodating variations in voltage during startup and driving conditions.
• Signal-to-noise ratio: ≥ 90 dB — Low noise floor helps preserve detail and dynamic range at high playback levels.
• Size (WxLxH): 9.4 x 6 x 2.2 inches — A compact footprint that fits in tight installations while leaving room for other equipment.

The MFA-2.420 is designed for flexible, high-power two-channel setups or a robust bridged sub solution in premium car audio builds, delivering strong output with selectable crossovers and a dense signal path optimized for audible detail with minimal footprint.
