Product Overview
Power a pair of car speakers or run a bridged mono setup with the Deaf Bonce MACHETE MFA-2.80, a compact 2-channel Class D car amplifier. It delivers up to 120 W x 2 at 2 Ω and includes adjustable low-pass and high-pass filters for shaping your system’s sound.
Key Features & Benefits
- Two-channel power: Choose 120 W x 2 at 2 Ω or 80 W x 2 at 4 Ω, with both ratings specified at 14.4 V.
- Bridged output: Use 240 W x 1 at 4 Ω for a compatible mono application.
- Adjustable filters: Set LPF and HPF from 50–12000 Hz to tailor the signal for your speakers.
- Simultaneous LPF and HPF: Both filters can operate together when your system calls for separate frequency ranges.
- Compact chassis: The 7.1 x 6 x 2.2 inch dimensions help you plan for a tighter installation space.

Why Choose This Product?
The MFA-2.80 gives you two ways to configure its output: run two channels or bridge the amplifier for a 4 Ω mono load. Its Class D design pairs that flexibility with a compact chassis, while the broad filter ranges let you adjust the signal to your system’s setup.
The stated signal-to-noise ratio is approximately 90 dB. Input sensitivity spans 0.4–8 V, providing a range for matching the amplifier to a source signal.
Installation & Compatibility Notes
Check your speaker or subwoofer impedance against the amplifier’s minimum load: 2 Ω per channel or 4 Ω when bridged. The listed working voltage is 9–15 V. Allow space for the 7.1 x 6 x 2.2 inch chassis, and plan connections for the 4 Ga input and 10 Ga output terminals.
Frequently Asked Questions
How much power does the MFA-2.80 produce?
It is rated at 120 W x 2 at 2 Ω and 80 W x 2 at 4 Ω, both at 14.4 V. Bridged output is 240 W x 1 at 4 Ω.
What is the minimum speaker load?
The minimum is 2 Ω per channel. In bridged mode, the minimum load is 4 Ω.
Can I use the low-pass and high-pass filters together?
Yes. The specifications state that LPF and HPF can operate simultaneously, with each filter adjustable from 50–12000 Hz.
Will it fit my installation space?
Compare the available space with the amplifier’s listed dimensions: 7.1 x 6 x 2.2 inches.
