DESC: esigned for life on the open water, the Dual MX-DM70 marine CD player/receiver makes a great foundation for a boat-based stereo system. The receiver features a powerful built-in amplifier (50 watts peak x 4) that powers a quartet of speakers, along with a host of marine-ready extras, such as clear-coated circuit boards, a rust-resistant chassis, and a detachable UV-resistant face with a negative white display. As a result, the stereo stands up to light rains, ocean spray, scorching sun, and almost any other weather condition. The CD player, meanwhile, is compatible with CDs and most CD-Rs, including discs loaded with WMA and MP3 files. The unit even displays track names and artist info on its black-and-white LCD screen, making it easy to find your favorite songs in the midst of a cross-lake cruise. And don't fret when you hit a huge wave, as the MX-DM70 includes an anti-shock mechanism that guarantees smooth playback in rough water.
