DS18 NXL-10SUB/BK HYDRO 10" 300W RMS 4-Ohm Marine Subwoofer with RGB LED Lighting, Black

The DS18 NXL-10SUB/BK HYDRO 10-inch marine subwoofer reinforces low-frequency output for open-air boats and off-road sound systems. This black single-voice-coil model is rated at 300W RMS and features integrated RGB accent lighting and an IP65-rated marine-oriented construction.

Key Features and Benefits

• 300W RMS continuous and 600W maximum power ratings; do not confuse the maximum figure with continuous amplifier output.
• Single 4-ohm voice coil simplifies matching to a suitable marine subwoofer amplifier.
• 2-inch glass-fiber-former voice coil and 72 oz ferrite magnet support controlled low-frequency operation.
• Integrated RGB lighting adds illuminated accent effects when wired to compatible LED control equipment.
• UV-protected composite basket and IP65-rated construction support exposed marine/powersports installations.
• Manufacturer-published Thiele/Small parameters assist enclosure and system-design planning.

Installation and System Integration

• Use a marine-rated 4-ohm-compatible amplifier and configure a subwoofer low-pass filter; DS18 recommends 100Hz.
• Cut a properly supported 8.78-inch opening and verify 5-inch rear clearance plus wiring and ventilation space.
• Provide separate RGB LED power/control connections; the audio voice coil and lighting are distinct circuits.
• Choose installation geometry and acoustic loading based on the published Thiele/Small parameters rather than assuming every bulkhead will reproduce the same bass response.

What's in the Box

• One 10-inch marine subwoofer
• Silicone protective cover
