BOSS Audio Systems MR508UABW Marine Stereo Single-DIN

BOSS Audio Systems MR508UABW is a weatherproof single‑DIN marine stereo that plays CDs, streams Bluetooth audio, accepts USB/aux inputs, and delivers four 50W channels for boat sound systems.

Whether you cruise, fish, or relax at the marina, the MR508UABW is built to keep music playing in wet, sun‑exposed environments. It combines multiple playback options — CD, AM/FM radio, Bluetooth streaming, USB, and aux — with weather‑resistant construction and UV protection so your audio source stays reliable on open water. A wireless remote and push‑to‑talk phone control add convenience while underway.

How does this stereo handle marine conditions?

The MR508UABW uses weatherproof housing and UV‑resistant coatings to resist corrosion, splashes, and sun damage typical of marine environments. It’s engineered so the internal electronics remain protected while mounted on consoles or dash panels exposed to the elements.

• water‑resistant chassis and seals block splashing water
• special UV coatings protect the face and enclosure
• durable materials reduce corrosion from salt air

What playback and connectivity options are available?

This unit supports a wide range of input methods to suit different listening preferences. Play discs in the CD/DVD slot, stream wirelessly via Bluetooth, access stored music from USB, plug in an MP3 player via aux, or tune AM/FM radio stations.

• Bluetooth audio streaming and phone calls with hands‑free control
• USB port for thumb drives and digital music libraries
• front auxiliary input for wired devices
• built‑in CD/DVD player and AM/FM tuner

How does it integrate with my boat’s speakers and controls?

The MR508UABW includes front and rear pre‑amp outputs to connect multi‑speaker setups, and it delivers up to 50 watts to each of four channels. The package also contains a wireless remote so you can adjust volume and switch sources from a distance without touching the head unit.

• four 50W channels for stereo and rear speaker connections
• front/rear line outputs for amplifiers or powered speakers
• compact single‑DIN footprint for standard marine dash installations
• wireless remote included for easier access

What extra features help with hands‑free use and convenience?

Voice and call handling are simplified with a Push To Talk button that links to your smartphone’s assistant over Bluetooth. This lets you accept calls, start navigation, or control music apps with minimal distraction while on the water.

• Push To Talk connects to phone assistants for voice commands
• Bluetooth enables hands‑free calling and wireless audio control
• compact dimensions (7" x 7.1" x 2.1") for common dash openings
• three‑year platinum dealer warranty included

Who is this for? If you need an affordably priced marine receiver that balances traditional media (CD and AM/FM) with modern conveniences (Bluetooth, USB, aux) and ruggedized protection for salt and sun, the BOSS Audio Systems MR508UABW is a practical choice. It suits boaters who want straightforward installation, reliable playback across multiple sources, and basic system expandability with pre‑amp outputs and a wireless remote.
