Deaf Bonce MACHETE MFA-5.1000 | 5-channel amplifier

The Deaf Bonce MACHETE MFA-5.1000 is a 5-channel Class D car amplifier with a dedicated sub channel, delivering 4 x 80W + 1 x 300W at 4Ω or 4 x 120W + 1 x 500W at 2Ω for flexible multi-amped setups.

• 5-channel Class D design: Efficient, compact topology that supports four full-range outputs plus a sub-channel in a single chassis, ideal for tight installs.
• Power RMS 4Ω (W): 4 x 80 + 1 x 300: Four channels provide 80W each into 4Ω, with a 300W dedicated sub channel for a single-amp sub setup.
• Power RMS 2Ω (W): 4 x 120 + 1 x 500: Lower impedance increases available power, enabling higher output on each of the four channels and a more powerful sub channel into 2Ω loads.
• Power RMS 4Ω bridged mode (W): 2 x 240: Bridge two channels on 4Ω to drive a higher-power mono sub or center channel for a more robust low end.
• Frequency response: 10-20000 Hz
• 1-4 channel High pass filter (Hz): 50 - 12000
• 1-4 channel Low pass filter (Hz): 50 - 12000
• 5 channel Low pass filter (Hz): 50 - 250
• 5 channel Subsonic (Hz): 10 - 55
• 5 channel Crossover (db/oct): 24
• LPF and HPF simultaneous operation: No
• Minimum permissible load on the channel: 2 Ohm
• Minimum permissible load in a bridge connection: 4 Ohm
• Input SPL: 0.4 - 6V
• Input terminal: 4 GA
• Output terminal: 8 GA
• Working voltage: 9 - 15V
• Signal-to-noise ratio: ~90 dB
• Size (WxLxH): 5.98 x 10.69 x 2.15 inch

The MFA-5.1000 is designed for multi-amp installations where four channels power front and rear speakers while a dedicated sub channel handles low-end performance. With selectable high-pass and low-pass filters, plus a subsonic control, you can tailor the output to match speakers, enclosure types, and vehicle acoustics. The 2Ω capability and bridged 4Ω mode provide flexibility for impedance matching and higher sub energy, while the 9–15V operating range fits typical automotive electrical systems.
