Deaf Bonce MACHETE MFA-4.80 | 80 Watt 4-channel amplifier

Deaf Bonce MACHETE MFA-4.80 is a 4-channel Class D amplifier built for serious multi-speaker car audio systems, delivering 120 W x 4 at 2 Ω, 80 W x 4 at 4 Ω, and 240 W x 2 in bridge mode.

• Class: 4-channel Class D—efficient power delivery with compact heat management suitable for under-dash or under-seat mounting in full-range setups.
• Power at 2 Ω: 120 W x 4 — enables higher output into low-impedance front/rear speaker loads, useful for loud, dynamic front stages.
• Power at 4 Ω: 80 W x 4 — steady, clean performance into typical 4 Ω speakers for balanced sound across channels.
• Bridge power (4 Ω): 240 W x 2 — two bridged outputs allow pairing channels for subwoofers or high-power mono channels in a two-bridge configuration.
• Frequency response: 20–20000 Hz — covers the full audible range for accurate reproduction of music and voice across the system.
• Minimum load: 2 Ω per channel; 4 Ω in bridge — supports low-impedance configurations while protecting stability in bridge mode.
• Input sensitivity: 0.4–8 V — compatible with a wide range of head units and preamp outputs for flexible integration.
• Filters: Low pass 50–12000 Hz; High pass 50–12000 Hz; LPF/HPF can operate simultaneously — precise active crossover control for front/rear or sub configuration.
• Crossover: 12 dB/Octave — steeper roll-off to minimize crosstalk between bands and improve imaging when using active networks.
• Terminals: Input terminal 4 Ga; Output terminal 10 Ga — indicates the gauge of wiring typically used for power and speaker connections in serious installs.
• Working voltage: 9–15 V — designed to tolerate typical automotive electrical variation without performance loss.
• Signal-to-noise ratio: 90 dB — low noise floor to preserve detail in midrange and vocal content in busy music passages.
• Size (W×L×H): 9.2 × 6 × 2.2 inches — compact footprint suitable for installation in tight spaces behind dashboards or under seats.

Benefits: The MFA-4.80 is well suited to a multi-amped system with a dedicated front stage and rear fill, or two bridged channels driving subwoofers for clean, high-power bass. Its flexible 0.4–8 V input range and 50–12000 Hz crossovers enable precise tuning with active networks, reducing reliance on external processors. The 2 Ω capability and 9–15 V supply support high-demand loads while maintaining stability, and the 9.2 × 6 × 2.2 inch chassis fits compact dashboards or under-seat enclosures without compromising performance.
