Compact IP66 Powersports 4-Channel Amplifier

The Memphis MX400.4 is a rugged, ultra-compact Class D amplifier specifically designed for powersports applications where space is limited and exposure to the elements is guaranteed. With an IP66 water-resistance rating, this amplifier is ideal for Side-by-Sides, ATVs, and motorcycles. It features conformal-coated circuit boards and water-resistant sealed plugs to ensure consistent performance in mud, rain, or snow.

Technically, the MX400.4 is a "micro" powerhouse, delivering 75 Watts RMS x 4 at 4 ohms or 100 Watts RMS x 4 at 2 ohms. Despite its small footprint (less than 9 inches long), it can be bridged to provide 200 Watts RMS x 2 at 4 ohms, making it capable of driving high-output tower speakers or small subwoofers. It also includes top-mounted controls protected by a water-resistant cover, allowing for easy gain and crossover adjustments even in tight mounting locations.
