Customer Reviews

It’s always interesting to find out what other consumers are saying about a product. It helps you make an informed decision based on personal experience by other users. These are some of the customer reviews we came across when reviewing the Boss MCKGB350.

One satisfied customer said the first time she took her boat out for a sail with the new MCKGB350 installed, she was blown away by its superior sound quality. She was convinced she would need subwoofers to enhance the sound for the party on the boat but didn’t need it at all. Perfect clarity and loud music all day.

Another customer expressed his surprise at how easy it was to use the RDS tuner to broadcast messages. He also loved that the marine antenna didn’t lose connection while he was out on the water listening to his favorite sports broadcast. His team won and he was ecstatic he didn’t miss the game while out sailing with family.

One suggestion posted by another user was to include CD and DVD inputs as their absence limits your listening experience. This customer was old-school and had all his music on CD & couldn’t play it while he was sailing. He was thankful for the AM/FM radio that at least allowed him to listen to the news.

Final Thoughts

Opting for a marine radio such as the Boss MCKGB350 is a beneficial investment. It can carry sound across noisy waters and is fully weatherproof. It comes with an antenna for easy tuning to an FM or AM station. It comes in handy if you need to broadcast an urgent message.

The sleek modern design is lightweight and super portable. It won’t stick out like a sore thumb as it blends in well with the dashboard interior of most boats. You have multiple connectivity options to access your favorite music, uninterrupted. It’s packed with sufficient power to last you a long time while you’re on board and can also keep your mobile phone charged up via the USB input.
