4-Channel Class D Full-Range Amplifier, 70 W x 4 @ 2 ohms / 50 W x 4 @ 4 ohms - 14.4V
Engineered specifically for powersports applications, the 4-channel MX280/4 amplifier employs our high-speed NexD™ switching design to deliver plenty of clean power, without straining charging systems. Its tiny, cast aluminum chassis is highly resistant to corrosion, with an IPX7 water-resistance rating, making it perfect for motorcycles, ATV’s or other utility vehicles.
Generating a solid 50W x 4 into 4 ohms (14.4V, 1% THD), the MX280/4 is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a potent 140W x 2 into 4 ohms.
Other features include independent front and rear crossovers with selectable full-range, high-pass or low-pass filter controls and a dual-range input section that accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals.
This amplifier features a rugged powder-coated finish, a gasketed cover for the controls and stainless steel hardware for durability.
