Give your boat's subwoofer the power it needs without giving up compartment space. The JL Audio AP300/1 is a compact monoblock amplifier built for subwoofer duty, delivering 300 W of clean Class D power. It is built to IP67 standards, excluding the cables, to hold up to the moisture, spray, and vibration of life on the water. An Easy Tune mode automatically adjusts the amplifier's settings for use with stereos that have DSP profile capability, which cuts setup time. An infrasonic filter is built in for cleaner low-frequency output. Pair it with a marine subwoofer such as the JL Audio M200 for a complete low-end upgrade. Wiring and fuse are sold separately.
