The Pyle PLCD7MRKT kit includes a head unit, four black 5.25" speakers and a splashproof tinted cover for the head unit. The 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 25 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 24-station memory. The LCD screen is backlit and shows relevant track info. A wireless remote control means you can change tracks without having to get up. For security, the anti-theft faceplate is detachable.
