® Kenwood DPX503U review – Best car audio offer

admin — Mon, 01 Feb 2010 19:33:05 +0000

If you have a Double-DIN sized dash opening in your car, fill it in style with the Kenwood DPX-503U CD/MP3 player. Designed to fit the double opening common in many newer cars, the stereo comes loaded with all of the performance features you’d expect from Kenwood.

Into digital music? The Kenwood DPX-503U plays back the MP3, WMA, and AAC music files that you’ve burned onto discs, and your song titles will appear on the four-line variable illumination full dot display. System Q-Ex EQ curves, along with sophisticated bass, treble, and midrange controls, let you shape the sound to your liking.

Kenwood DPX-503U also has a handy USB input allows you to connect an iPod or portable music player. Just plug your compatible iPod, pen drive, portable hard drive or other USB device into the front USB on the stereo. The radio will display artist names and track information right on the faceplate, and the USB socket will even supply power to your compatible player.
