Product Overview

Build a flexible car-audio system with the Deaf Bonce MACHETE MFA-2.420, a compact, two-channel Class D amplifier. It delivers 420 W × 2 at 4 Ohm or can be bridged for 1260 W × 1 at 4 Ohm, with selectable high-pass and low-pass filters.

Key Features & Benefits

• Two-channel output: Use the channels independently or bridge them for a single 4 Ohm load.
• Power options: Choose between 630 W × 2 at 2 Ohm and 420 W × 2 at 4 Ohm, both rated at 14.4 V.
• Adjustable filters: Set the high-pass and low-pass filters from 50–12,000 Hz to shape the output for your system.
• Simultaneous filtering: Run LPF and HPF together when your setup calls for both filters.
• Compact dimensions: Its 9.4 × 6 × 2.2-inch size helps you plan for a space-conscious installation.

Technical Specifications

Why Choose This Product?

The MFA-2.420 gives you two ways to plan your amplifier setup: run two channels or use the specified bridged 4 Ohm configuration. Its full 20–20,000 Hz frequency response and adjustable filters provide options for shaping the signal around your system’s needs.

The 12 dB/Oct crossover and simultaneous LPF and HPF operation offer further control when setting filter ranges. The compact chassis also helps when planning an installation with limited space.

Installation & Compatibility Notes

Match your speaker or bridged load to the listed minimums: 2 Ohm per channel or 4 Ohm in bridge mode. The working voltage is 9–15 V, and the input range is 0.4–8V. Check available mounting space against the 9.4 × 6 × 2.2-inch dimensions and confirm your system’s load and voltage requirements before installation.
