This tiny waterproof stereo is great for applications where limited space is available. Even though it is only gauge size, it can still power up to 4 speakers with 40 watts (peak power) per channel. 
This stereo has no CD player. Instead it has an AM/FM radio and RCA Aux audio inputs on the rear which can be used to play the audio from iPods, portable satellite radios, etc. It also will play your digital MP3 files when you connect your MP3 player or Flash drive to the rear USB port (MP3 players will also be recharged).
