With Alpine's CDA-9807 CD receiver, you can listen to MP3 and Windows Media (WMA) files when you're on the go — without bringing any extra equipment. Just record your music onto disc, and you're ready to roll! With all that music available (up to 10 hours per disc), sometimes you need to find a specific song. Alpine makes it easy to navigate through the disc.
Your tunes are brought to life by 4 channels of 23 watts RMS MOSFET power. Media Xpander™ restores the life that's lost when music is broadcast or compressed. Alpine's Bass Engine® lets you pick the bass and treble center frequencies, choose the width of the bass boost, and adjust the subwoofer level, so you can refine the sound until it's as polished as the CDA-9807's sleek silver and blue faceplate.
Put 6 or 12 discs at your command by adding an Alpine CD changer, or use the optional adapter to convert the changer controls to an auxiliary input. Something else you'll want to add is Alpine's XM Satellite Radio tuner and an XM antenna so you can activate your XM service. Give it a try and you'll wonder how you ever listened to radio before XM!
