JL Audio MX500/1: Mono Class D Full-Range Amplifier, 500W Water Resistant Ultra-Compact

Compact Mono Class D water resistant amp

Monoblock Class D Wide-Range Amplifier, 500 W x 1 @ 2 Ω / 300 W x 1 @ 4 Ω - 14.4V

Engineered specifically for powersports applications, the MX500/1 monoblock amplifier employs our high-speed NexD™ switching design to pack a serious audio punch, without straining charging systems. Its tiny, cast aluminum chassis is highly resistant to corrosion, with an IPX6 water-resistance rating, making it perfect for motorcycles, ATV’s or other utility vehicles.

With a robust 500W of clean power into a 2-ohm load (14.4V, 1% THD), use one to drive a subwoofer, or grab a pair to deliver stunning output to a subwoofer system. The MX500/1 also features an adjustable low-pass crossover, a bass boost EQ, variable infrasonic filter and output polarity switch.

Its dual-range input section accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals. With the addition of an M-RBC-1 remote level control (sold separately), subwoofer output can be directly controlled from the driver’s seat.

This amplifier features a black powder-coated finish, a gasketed cover for the controls and stainless steel hardware for durability.
