Pyle's Hydra series has the solution for your marine audio needs - this PLCD9MR white head unit 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's rated at 4 x 40 watts, 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 wireless 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.
