Deaf Bonce MACHETE MLA-70.2 XS | 70 Watt 2-channel amplifier

The Deaf Bonce MACHETE MFA-2.520 is a 2‑channel Class D amplifier built for high‑current car audio installs, delivering 750 W per channel into 2 Ω and 1500 W bridged into 4 Ω for demanding front/sub configurations.

• Model: MFA-2.520 — Precise model identifier used for compatibility and service reference.
• Class: D — Efficient switching design that reduces heat and allows compact chassis in performance builds.
• Number of the channels: 2 — Separate output channels suitable for a stereo front stage or paired channels for a bridged sub setup.
• Frequency response: 20–20000 Hz — Covers the full audible spectrum, from deep bass to shimmering highs.
• 2 Ohm RMS Power (14.4 V): 750 W x 2 — High power delivery into low-impedance loads for louder, cleaner output per channel.
• 4 Ohm RMS Power (14.4 V): 520 W x 2 — Strong per‑channel performance at 4 Ω, suitable for mid/high drivers in a two‑channel setup.
• 4 Ohm RMS Power (Bridge): 1500 W x 1 — Bridged operation provides substantial single‑channel power for a sub or mono output with a 4 Ω load.
• Minimum permissible load on the channel: 2 Ohm — The amp can operate down to 2 Ω per channel, enabling low‑impedance speaker choices.
• Minimum permissible load in a bridge connection: 4 Ohm — When bridged, keep the load at 4 Ω or higher for safe operation.
• Input SPL: 0.4–8 V — Defines the input signal range needed to reach full power from a compatible head unit.
• Low pass filter: 50–12000 Hz — Set the high‑frequency cutoff to tailor bass/woofer or sub performance.
• High pass filter: 50–12000 Hz — Excludes bass or low‑frequency content from a channel to protect drivers and tighten response.
• LPF and HPF simultaneous operation: True — You can run both filters at once for precise, multi‑way tuning on a two‑channel setup.
• Crossover: 12 dB/Oct — Steeper slope for cleaner separation between drivers, reducing overlap and masking.
• Input terminal: 4 Ga — Requires a 4 AWG power wire for proper supply capability in high‑current installs.
• Output terminal: 8 Ga — Uses an 8 AWG conductor for power output connections to the vehicle wiring.
• Working voltage: 9–15 V — Designed to operate within typical automotive electrical systems.
• Signal‑to‑noise ratio: ~90 dB — Reflects low background noise for clearer, more dynamic sound under typical car conditions.
• Size (WxLxH): 11 x 6 x 2.2 inch — Compact footprint suitable for under‑seat or dash installations with room to spare.

Benefits: In a two‑channel or bridged configuration, this amp provides robust, clean power with flexible filtering to tailor a multi‑driver system. The wide frequency range, generous low‑impedance capability, and adjustable LPF/HPF allow precise tuning for a cohesive, high‑fidelity car audio build while staying within vehicle electrical limits and accommodating standard head units.
