🔊 DS18 MRX300 Marine Stereo – Big Sound, Rugged Build, Fully Marine-Ready
When you're out on the water, your audio gear needs to work as hard as you do. The DS18 MRX300 Marine Stereo is built for those who want premium sound with no compromises—even in wet, sun-soaked conditions. This stereo head unit offers power, precision, and cutting-edge technology in one compact, water-resistant package.
Whether you're taking the jet boat for a weekend cruise or fishing at sunrise, the MRX300 ensures your soundtrack plays loud and clear.
⚡ Built Tough for Harsh Marine Conditions
Marine environments are rough on electronics. Salt, sun, and water can take their toll fast. The MRX300 marine stereo fights back with rugged construction designed for life on the water. It’s IP65-rated, which means it resists water, dust, and spray.
The screen is UV-resistant and stays visible in bright daylight. Buttons are sealed and rubberized for a responsive feel—even with wet fingers. It won’t corrode or crack, no matter how many summers it sees.
This unit is built for open boats, pontoons, center consoles, and more.
🎶 Versatile Audio Sources for Endless Entertainment
The MRX300 marine stereo plays what you want, how you want it. With support for Bluetooth 5.0, USB, AUX, and AM/FM radio, you’ll always have music at your fingertips. Pair your phone in seconds and stream high-quality audio wirelessly. Or plug into the rear USB or AUX inputs for direct control.
Want to use a media player or SD card? No problem. The stereo reads a wide range of formats and delivers them through a clean, powerful preamp output.
It’s the marine stereo that offers full connectivity without a clunky interface.
🔉 Two-Zone Audio for More Control
The MRX300 offers dual-zone output, giving you precise control over front and rear speakers. You can lower the volume near the helm and pump it up at the bow. It’s perfect for larger boats or any setup that needs customized audio across different zones.
You’ll enjoy clean, distortion-free sound thanks to the 4 x 50-watt internal amplifier. Add a marine amplifier or subwoofer later via RCA outputs for expanded performance.

🧰 Easy Fit with Gauge-Style Mounting
The MRX300 features a standard gauge-style design. It mounts easily in most dashboards or control panels with minimal cutting. Its compact chassis fits tight spaces, making it great for new installs or retrofits.
DS18 includes the wiring harness and hardware needed for quick, secure installation. The interface is intuitive and button-based, with a vibrant 3-inch TFT color display.
🛡️ Protect Your System with Marine Window Tint
Sun and heat can ruin electronics faster than water. Protect your stereo and your boat’s interior with high-performance window tint.
We recommend Window Tint Delaware for professional-grade marine window tint. Their films reduce heat, glare, and UV exposure while improving visibility and extending stereo life.
It’s a smart upgrade for enclosed consoles, cabins, or shaded seating areas.
