Compact Powersports Amplifier

The MTX MUD 50.2 is a 2-channel class D amplifier built for UTV, marine and motorcycle audio systems. It delivers 50 watts RMS per channel at a 2-ohm load and 100 watts RMS total in a chassis that is the most compact MTX has produced. The unit carries a conformal coating for weather resistance in outdoor environments. The design focuses on thermal efficiency and sound quality for powersports installations.

Suited for limited-space outdoor audio

This amplifier fits riders who need a small, weather-resistant unit to drive one or two full-range speakers per channel on a 2-ohm load. Buyers who want more channels, higher per-channel output, or an amplifier designed for home-theater speaker systems should look at other products. The 5.00 dimension and class D topology serve space-constrained vehicle mounting, not indoor component racks.

50 watts RMS per channel at 2 ohms

This single power rating decides whether the amp matches your speaker impedance and volume target. Confirm that your speakers present a 2-ohm load per channel and that 50 watts RMS meets your output requirement before purchasing. The specification is the primary filter for compatibility.

Questions about this item

Does the MTX MUD502 come with mounting hardware and wiring, or do I need to buy a separate installation kit?

The amplifier is supplied as the unit only; mounting brackets, power wire, speaker wire and RCA cables are not included and must be purchased separately.

Should I choose the 25 W RMS per channel spec or the 50 W RMS per channel spec for my system?

The 25 W RMS x 2 rating applies at 4 ohms; the 50 W RMS x 2 rating applies at 2 ohms. Match the figure to the impedance of the speakers you plan to connect.

What does 50 W RMS at 2 ohms mean when the amp is installed on my UTV?

Each channel can deliver 50 watts continuously into a 2-ohm load, so a pair of 2-ohm speakers will receive full rated power per channel.
