Compact four-channel amplifier for powersports

The MTX MUD100.4 is a class D amplifier built for ATVs, UTVs and motorcycles. It delivers 100 watts RMS per channel across four channels for a total of 400 watts RMS. A conformal-coated circuit board and sealed control covers protect the electronics from moisture and mud. A single pigtail harness carries power, ground and signal connections to simplify installation.

Riders who need a small, weather-sealed amp

This unit suits owners who want to add or upgrade speakers on open-cockpit vehicles where space is tight and exposure to water or dust is constant. The tiny chassis fits behind many factory radios and resists radio-frequency interference. Buyers who require more than four channels or higher per-channel power should consider a larger amplifier.

Included pigtail harness removes separate wiring

The bundled pigtail combines every necessary conductor into one plug-in assembly. It eliminates the need to crimp or solder individual power, ground and speaker wires. Installers can route the single loom, connect the amp and finish the job faster with fewer failure points.

Questions about this item

What power and ground wiring is needed to run this 400-watt RMS amplifier kit?

The kit includes a pigtail harness that carries power, ground and signal wires so no separate cable assembly is required.

Will this four-channel amp work with the factory radio already on my motorcycle?

Its compact footprint matches most OEM motorcycle radios and the design resists radio-frequency interference for clean integration.

How can I confirm each channel is delivering the rated 100 watts RMS after installation?

Measure AC voltage across the speaker terminals with a test tone at full volume; the reading should match the expected output for a 100-watt RMS channel into your speaker load.
