JL Audio XDM300/1 Monoblock Class-D Car and Marine Amplifier 300W

The JL Audio XDM300/1 proves that big bass doesn’t require big space. Using advanced NexD™ high-speed switching design, this ultra-efficient Class D monoblock amplifier delivers clean, controlled low-frequency power while remaining small enough to fit into the tightest installations. Producing 300 Watts RMS at 2 Ohms, it is perfectly suited for driving compact subwoofer systems in cars, marine vessels and powersports applications where space and efficiency are critical. Built with marine-grade materials, the XDM300/1 is engineered for reliable performance in harsh environments, making it equally at home in boats and vehicles. A dual-mode input filter ensures noise-free operation in both automotive and marine systems, while automatic turn-on via signal or DC-offset sensing simplifies installation with factory audio systems. The integrated variable low-pass filter (50–500 Hz) allows precise bass tuning, and compatibility with optional JL Audio remote level controls enables convenient adjustment from the driver’s seat or helm.
