Our take on the Boss MRH7

by Jon Paulette

A safe harbor for your marine receiver

If you want to upgrade the audio system in your boat, but don't have enough space for an "in-dash" receiver, this MRH7 waterproof radio housing from Boss is the ideal solution. It'll house and protect a wide selection of single-DIN (2" tall) marine receivers, and its universal mounting bracket makes it easy to install in the best spot on your boat.

The rugged, marine-rated housing is more than tough enough for life on the water. The UV-stabilized ABS plastic housing won't crack and fade in broiling sunlight, while the poly-carbonate tinted front panel and heavy-duty gasket protect your receiver from salt and spray. Boss even includes external wiring for connecting your power, speakers, and amp, so water can't get in.

Receiver not included.
