DS18 NXL-N2 HYDRO 2-Channel Full-Range Nano Class D Marine & Powersports Amplifier, 2 x 100W RMS at 4 ohms, IP67

The DS18 NXL-N2 HYDRO amplifier is designed to drive marine and powersports speakers with efficient Class D amplification. Its IP67-rated enclosure and variable audio adjustments make it suitable for boat, UTV, and off-road installations while preserving the distinct power specifications at each load impedance.

Key Features

• High-efficiency Class D output stage supports installation in constrained marine/powersports compartments.
• 2 x 100W RMS at 4 ohms; individual load-specific ratings are listed below.
• Adjustable filtering supports speaker protection and system tuning.
• IP67 water-resistance classification; corrosion-conscious electrical installation remains essential.
• Integrated power, protect and clipping status indication and protective circuitry.
• Stereo operation and supported bridged configuration provide flexible choices for full-range speaker systems.

Installation & System Integration

Provide a dedicated fused battery feed sized to the amplifier power demand, a short solid ground, sufficient mounting clearance and serviceable signal wiring. Connect each channel only to a supported speaker impedance. Bridged ratings require the specified 4-ohm load. Tune gain and active filters with the system playing cleanly rather than using gain as a volume control. Keep wiring, terminals and mounting points protected from saltwater and prolonged water immersion.

Compatibility

Use with 12V marine/powersports audio systems and speakers wired to meet the manufacturer-listed minimum impedances. Monoblock models drive subwoofer loads; multi-channel full-range/subwoofer models provide independent speaker and bass outputs.
