Deaf Bonce MACHETE MFA-1.800 | 800 Watt Power Amplifier

The Deaf Bonce MACHETE MFA-1.800 is a 1-channel Class D mono amplifier delivering 800 W RMS into 1 Ω from a 14.4 V system, built for demanding subwoofer setups in high-performance car builds.

• 1-channel Class D design: high efficiency and compact size, ideal for a dedicated subwoofer power stage in a tight install.
• RMS Power (14.4 V) at 1 Ω: 800 W: maximum sustained power into a very low-impedance load, enabling strong bass output when paired with an appropriate sub and enclosure.
• RMS Power (14.4 V) at 2 Ω: 570 W: substantial power with slightly higher impedance, balancing performance and heat management.
• RMS Power (14.4 V) at 4 Ω: 340 W: reliable mid-range/low-end performance when driven into a higher impedance voice coil.
• Minimum permissible load on the channel: 1 Ω: the amp is designed to operate with at least 1-ohm loads, allowing aggressive subwoofer configurations.
• Low pass filter: 50-250 Hz: restricts output to bass frequencies, helping to integrate the sub with other speakers by attenuating mid/high content.
• Crossover: 24 dB/Oct: steep attenuation slope to improve bass separation and reduce bleed into higher frequencies.
• Subsonic filter: 10-55 Hz: protects the sub from ultra-low-frequency energy that can cause excessive cone motion and distortion.
• Input terminal: 4 Ga; Output terminal: 8 Ga: specifies wiring requirements for robust power delivery and grounding in installs.
• Working voltage: 9-15 V: compatible with typical automotive electrical systems and their voltage variations.
• Frequency response: 10-250 Hz: optimized for deep bass and subwoofer performance, capturing the essential low-end range.
• Signal‑to‑noise ratio: 160 dB: very low inherent noise for clean bass amplification when driving a subwoofer.
• Size (WxLxH): 7.5 x 6 x 2.1 inch: compact footprint suitable for tight spaces in trunks or under seats.

The MFA-1.800 serves as a focused mono power stage for subwoofers, delivering substantial bass authority with programmable filtering to shape and protect the low end. Its 1 Ω capability, high SNR, and compact form factor make it a practical choice for serious bass builds where precise tuning and minimal footprint matter.
