JL Audio HX300/1

Monoblock Class D Full-Range Amplifier, 300W x 1 @ 2Ω / 160W x 1 @ 4Ω - 14.4V

Engineered specifically for powersports applications, the HX300/1 monoblock amplifier employs our high-speed NexD™ switching design to pack a serious full-range 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 300W 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 or full-range satellites. The HX300/1 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.
