What does 80W RMS mean in practice?

Each of the four channels delivers 80W RMS continuously, which is enough for most factory-replacement door speakers. Bridging two channels sends more power to a single speaker or subwoofer.

Can I run front speakers and a subwoofer from it?

Yes. The four channels can power front and rear speakers, or two channels can drive speakers while the other two are bridged for a subwoofer. The simultaneous LPF and HPF let you filter each pair separately.

Is it hard to install?

It uses 4-gauge power input and 8-gauge speaker outputs, standard for this class. The 43.2-inch width and 5 kg weight mean you need a solid mounting spot with room for wiring.

How does it compare with Class AB amps?

Class D runs cooler and draws less current, which suits tight installs and stock electrical systems. Some listeners find Class AB warmer, but at this power level the difference is small.

The amplifier itself. Power and speaker wiring, fuses and mounting hardware are typically sold separately, so check before installing.

Our take on the Machete MLA-80.4 XS 80W 4-Channel Amplifier

The Machete MLA-80.4 is a compact Class D four-channel car amplifier rated at 80W RMS, bridgeable for more power to fewer speakers. It runs low-pass and high-pass filters at the same time, so front and rear or component and subwoofer setups can be tuned separately. Its 85 dB signal-to-noise ratio and 20 Hz–20 kHz response are modest next to premium four-channel amps, and the 5 kg body is heavier than many small Class D units. It suits budget-minded drivers who want flexible filtering and bridging without paying for high-end power.
