Engineered specifically for powersports applications, the 4 channel MX500/4 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 or other utility vehicles. Generating a solid 70 W x 4 into 4 Ohm (14.4 V, 1% THD), the MX500/4 is fully bridgeable, so it can be used as a 3 channel amplifier or as a 2 channel amplifier producing a potent 250 W x 2 into 4 Ohm. 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 black powder coated finish, a gasketed cover for the controls and stainless steel hardware for durability.
