Most Compact MTX Amplifier
If you want big power in a small package, look no further than the MTX MUD50-2 UTV Amplifier. It’s the most compact amplifier MTX has ever made. That means you can find space for it even on the tiniest vehicles—it’s a universal fit so you can put it on anything from quads to boats to motorcycles. No matter where you’re trying to get your boogie on, this amplifier will fit right in.

Small Package, Big Sound
This compact amplifier delivers big results. It features full range class D topology for incredible sound quality and thermal efficiency. And you get 2 channels capable of 50 watts of RMS power per channel. That’s more than enough power for your speakers.

Ready for Rugged Conditions
We know you need a rugged amplifier, and this bad boy delivers. MTX uses a pigtail wiring design to connect power, ground, and signal without making a connection directly at the amplifier. That means all the crud and moisture that could corrode internal electrical components stays outside where it belongs. Plus, the entire unit is weather-resistant, including a coated circuit board and controls.
