DS18 NXL-N4BT HYDRO Nano Series 4-Channel Class-D Marine Amplifier with Built-In Bluetooth
Transform the audio experience in your marine vessel, UTV, or motorcycle with the DS18 NXL-N4BT, a robust 4-channel amplifier from their rugged HYDRO Nano series. What sets this model apart is its integrated Bluetooth receiver, allowing you to stream high-quality audio directly from your smartphone or Bluetooth-enabled device—completely eliminating the need for a traditional head unit. Engineered to deliver massive, full-range power to multiple speakers, this highly efficient Class-D amplifier pumps out 150 watts RMS per channel at 2 ohms, 100 watts RMS per channel at 4 ohms, or a massive 300 watts RMS x 2 channels bridged at 4 ohms. Whether you are driving a set of wake tower speakers or outfitting your side-by-side with a complete custom "headless" sound system, the NXL-N4BT provides dynamic, crystal-clear power in extreme outdoor environments.
Designed to withstand the absolute harshest conditions on land or water, the NXL-N4BT boasts a strict IP67 waterproof rating, ensuring complete protection against moisture, mud, salt, and dust. Internally, it features a highly stable 4-layer PCB layout built with reliable Surface Mount Component (SMC) technology, ensuring flawless performance even under extreme off-road vibration or pounding boat wakes. The extruded aluminum chassis—styled in DS18’s signature black and red finish—acts as a highly efficient heat sink to keep the amplifier running cool. With an incredibly small footprint, this "Nano" amplifier can be stealthily tucked away in the tightest spaces, giving you a powerful, invisible audio system backed by comprehensive multi-way protection circuitry.

Key Features & Specifications
- Integrated Bluetooth: Features a built-in Bluetooth receiver for direct wireless audio streaming, perfect for powersports and marine setups where mounting a standard radio isn't feasible.
- RMS Power Output: Delivers 150W x 4 channels @ 2-Ohms, 100W x 4 channels @ 4-Ohms, or bridged 300W x 2 channels @ 4-Ohms (1800W Peak Power).
- Marine & Powersports Ready: Carries a strict IP67 waterproof rating, making it completely protected against direct water spray, mud, salt, and dust for true all-weather reliability.
- Class D Efficiency: Utilizes a high-efficiency, full-range digital Class D design with a stable 4-layer PCB layout to generate massive power with minimal current draw on your charging system.
- Ultra-Compact "Nano" Footprint: Measuring approximately 9.84" L x 3.67" W x 1.56" H, its micro-sized chassis allows for incredibly stealthy, out-of-sight installations inside fairings or under seats.
- Audio Tuning: Equipped with independent front and rear selectable crossovers (HPF / LPF / FULL) and a variable filter range of 40Hz to 500Hz to properly tune mids, highs, or bridged subwoofers.
- Smart Protection: Features an integrated LED status indicator and comprehensive protection circuitry (thermal, overload, DC output, short circuit, and high/low voltage input protection).
- Wiring Configuration: Pre-wired with heavy-duty OFC (Oxygen-Free Copper) power, ground, and speaker pigtails for maximum current transfer and a watertight, corrosion-resistant installation.
