The DEH-S120UB lets you listen to your favorite music from FM radio stations, Android smartphones, USB devices or via the Aux-in connection. This easy-to-use car stereo plays music with 4 x 50W of pure, guaranteed MOSFET power. If that's not enough, you can use the RCA pre-out to connect another stereo component, such as a subwoofer or an additional amplifier for the front and rear speakers.
