Small, but mighty

The MUD100.4 is the most compact amp in the MTX line. In fact, it's one of the smallest amps they've ever made. Class D technology allows this diminutive amp to put out huge sound with remarkable thermal efficiency, delivering 50 watts RMS per channel to four 4-ohm full-range speakers or 100 watts to 2-ohm speakers. Or you could run a pair of speakers plus a subwoofer — with up to 200 watts going to the sub.

Ready to ride

MTX made this weather-resistant amp for on-road travel and off-road adventure, with a conformal coated circuit board and control covers that keep moisture from spoiling the fun. Its unique design includes a pigtail that contains the power, ground, and signal wires so there are no direct connections on the amplifier. This protects the internal components from moisture, dirt, and other hazards, so you'll be able to have fun without worrying about how your amp's holding up.
