Product Overview
Build a four-channel car audio system around the Deaf Bonce MACHETE MFA-4.120 Class D amplifier. It delivers different RMS power ratings at 2- and 4-ohm loads, with bridge capability and adjustable low- and high-pass filters for flexible system setup.
Key Features & Benefits
- Four channels: Power separate channels in a multi-channel car audio installation.
- Bridge capability: Bridge channels for a higher-power output, subject to the stated load requirements.
- Adjustable filters: Low-pass and high-pass filters each cover 50–12000 Hz, helping tailor the signal to your system.
- Simultaneous filter operation: LPF and HPF can operate together for additional crossover flexibility.
- Wide input sensitivity range: The 0.4–8 V input range supports connection with a range of source units.

Why Choose This Product?
The MFA-4.120 gives you four channels for a multi-channel setup, with the option to bridge channels when your system calls for it. Its 12 dB/Oct crossover and independently listed LPF and HPF ranges offer practical ways to shape the signal for your chosen configuration.
Power ratings are specified by load, and bridged operation has its own minimum load requirement. Use those distinctions when planning your amplifier and connected equipment.
Installation & Compatibility Notes
Plan your installation around the amplifier’s 9–15V working voltage, 4 Ga input terminal, and 10 Ga output terminal. Allow space for its 9.7 x 6 x 2.2 inch dimensions, listed as width, length, and height.
Confirm the connected load meets the minimum for the selected channel or bridged configuration. The power ratings are stated at 14.4 V where indicated; match your setup to the appropriate rating and connection arrangement.
Frequently Asked Questions
What is the difference between the channel and bridged power ratings?
The amplifier lists separate RMS ratings for four-channel operation at two load values, plus a bridged rating. Choose the rating that matches your planned wiring and load.
What minimum load is required?
The listed minimum is 2 Ohm per channel and 4 Ohm for a bridged connection.
Can the low-pass and high-pass filters operate at the same time?
Yes. The specifications state that LPF and HPF simultaneous operation is supported.
Will it fit in my vehicle?
Compare the listed amplifier dimensions with your intended mounting space and check your vehicle installation requirements before planning the fit.
