Product Overview
The Deaf Bonce MACHETE MFA-4.80 is a four-channel Class D car audio amplifier for building a flexible multi-speaker system. It delivers 80 W x 4 RMS at 4 Ω, with higher output at 2 Ω and two bridged outputs for system designs that need a different channel arrangement.
Key Features & Benefits
- Four channels: Power multiple speakers from one amplifier in a front-and-rear setup.
- Selectable load ratings: The amplifier is rated for 120 W x 4 RMS at 2 Ω or 80 W x 4 RMS at 4 Ω, both at 14.4 V.
- Bridge power: Two bridged outputs provide 240 W x 2 RMS at 4 Ω.
- Adjustable filters: Low-pass and high-pass filters each cover 50–12000 Hz for tuning connected system components.
- Flexible input range: The 0.4–8 V input range supports integration with a range of head-unit and preamp outputs.
- Compact dimensions: Its 9.2 x 6 x 2.2 inch size helps with planning an installation where space is limited.

Why Choose This Product?
The MFA-4.80 gives you four channels with multiple rated power options, so you can plan around the speaker loads in your system. Its bridge rating also offers another configuration option when two channels are paired.
The independently listed low-pass and high-pass ranges both span 50–12000 Hz, and the specifications state that they can operate simultaneously. That gives you crossover adjustment options within the amplifier when tuning your setup.
Installation & Compatibility Notes
Check each speaker load against the amplifier’s minimum ratings: 2 Ω per channel or 4 Ω in a bridged connection. Use the matching power rating for the load and operating configuration when planning your system.
Allow for the 9.2 x 6 x 2.2 inch chassis when choosing an installation location. The listed working voltage is 9–15V; confirm your vehicle’s electrical system and installation requirements before connecting the amplifier.
