The high contrast display with black characters on a white background remains visible in all lighting conditions, from darkness to direct sunlight. For connectivity, it boasts built-in Bluetooth for hands-free calls and music streaming, along with USB and aux inputs for versatile audio options.

The stereo is compatible with various devices such as smartphones and speakers, and it supports multiple audio formats, including the high-quality FLAC files, making it appealing to sound quality enthusiasts. The presence of an equalizer and digital time alignment allows for customizable audio settings through the display or an app. Its multi-color illumination adds a customizable aesthetic touch to the setup.

Some limitations include its 2-channel audio output, which may not satisfy those looking for a more immersive surround sound experience. Additionally, while it is SiriusXM ready, users will need to purchase a separate tuner for satellite radio functionality. Its relatively lightweight build at 1.5 pounds is an advantage for installation but may not assure the same durability as heavier models. Despite minor drawbacks, the KENWOOD KMR-M332BT remains a solid choice for those seeking a durable and feature-rich marine stereo with good audio quality and reliable performance in challenging environments.

The BOSS Audio Systems MGR350B Marine Boat Stereo is a solid choice for boat owners looking for a rugged and versatile sound system. It is equipped with Bluetooth, allowing you to play and control music from your smartphone or MP3 player, and supports popular apps like Spotify and Pandora. The stereo's waterproof rating of IPX6 ensures protection against splashing water, and the front panel UV coating adds resistance to the sun's rays, enhancing its durability in harsh marine environments. The conformal coating on the PC board further boosts its weatherproofing capabilities. However, it does not include a CD/DVD player, which might be a drawback for users who prefer physical media.

With a built-in 4-channel amplifier delivering 60 watts per channel, it offers decent power output for a stereo of its size. Connectivity options are ample, with USB and auxiliary inputs, as well as pre-amp outputs for speakers or subwoofers. Its compact dimensions and light weight make it easy to install, though it is recommended to have it professionally installed to ensure optimal performance.

The audio quality is generally well-regarded by users, and the 3-year warranty provided by BOSS Audio Systems adds peace of mind. In summary, this marine stereo is a reliable and durable option for boat enthusiasts prioritizing Bluetooth connectivity and weather resistance over a built-in CD/DVD player.
