The Pyle PLCD15MR is capable of tuning AM/FM, playing audio and MP3 CDs and has an auxiliary input to plug in another device like an iPod or MP3 player. It is rated at 4 x 60 W, so each speaker has plenty of independent power. And it comes with everything you've come to expect from a modern head unit: 3-beam laser tracking, anti-skip mechanism, loudness settings and a 30-station memory. The LCD screen is backlit and shows relevant track info. A wired remote control with display means you can change tracks without having to get up. For security, the anti-theft faceplate is detachable. Pyle's head units will have your music sounding great at the dock or in the middle of the ocean.
