Description
The Deaf Bonce MACHETE MFA-4.220 is a 4-channel Class D car amplifier built for demanding multi-speaker setups, delivering strong multi-channel power with precise crossover control. It provides 330 W x 4 at 2 Ω and 220 W x 4 at 4 Ω (14.4 V), with 660 W x 2 available in bridge mode across a 4 Ω load, and covers a wide audio bandwidth from 20 Hz to 20 kHz.
- 4-channel Class D architecture: High-efficiency, high-current design tailored for four full-range channels while maintaining thermal stability in a compact form.
- Power output: 2 Ω RMS 330 W x 4; 4 Ω RMS 220 W x 4; Bridge 660 W x 2 into 4 Ω, enabling flexible speaker configurations in a single chassis.
- Bridge mode capable: Ability to pair channels for increased subwoofer or dedicated low-end power without adding a separate amp.
- Frequency response: 20 Hz–20 kHz, ensuring faithful reproduction from deep bass to crisp highs for a complete music signal.
- Input sensitivity: 0.4–8 V, accommodating a wide range of preamp outputs and head units for scalable system integration.
- Filters and crossover: Low pass 50–12,000 Hz; High pass 50–12,000 Hz; LPF and HPF can operate simultaneously at 12 dB/Oct for precise signal separation.
- Terminals: 4 Ga input terminal and 10 Ga output terminal, supporting high-current wiring for stable power delivery.
- Working voltage: 9–15 V, designed for typical automotive electrical systems and practical in-vehicle installation scenarios.
- Signal-to-noise ratio: Approximately 90 dB, contributing to clean amplification even at higher output levels.
- Dimensions: Size (WxLxH) 10.5 x 6 x 2.2 inch, compact enough for under-seat or trunk installations while maintaining ample heat dissipation.
Benefits: The MFA-4.220 is well-suited to a premium four-speaker system, delivering solid, low-noise power to front and rear channels with adjustable crossovers for precise tonal balance. Its simultaneous LPF/HPF operation and 12 dB/Oct slope enable clean separation between sub, midrange, and highs, minimizing distortion and driver stress. Bridge mode provides a straightforward path to adding a subwoofer or higher-output pair without additional amplifiers, while the robust 4 Ga/10 Ga wiring compatibility and 9–15 V operating range align with typical vehicle installations for reliable performance.
