The Boss 610UA 200W Audio System is an affordable upgrade to any automotive stereo system. Play music from you Android, iPhone, MP3 player, or any other device. Charge your phone while it plays with the USB port. Pass the Aux and share music with friends on your next road trip. Toss together a mix tape and load it on a USB device or SD card and play tracks from there. The sound system plays the standard MP3 and WMA audio files. Get the chords to sound just right or let that heavy bass drop with the 4 channel equalizer that allows for custom sound quality. Didn't bring any music along with you?
