Awesome amplification for banging beats.\n\nThe DEH-150MPG's built-in amplifiers produce pristine sound delivered at 4 x 50W of pure, proven MOSFET power. If that isn't enough, you can always use the RCA pre-out to hook up another stereo component, like an extra amp for the rear speakers for example.\n\nYou can play tunes from traditional CDs or CD-R/RW, including MP3, WMA and WAV files. If your music is stored on a portable device, like an iPod or a mobile phone, the front panel's green, illuminated Aux-in gives them a direct connection to your car speakers via the DEH-150MPG sound system.
