About the Alpine CDE-121
Play and charge your iPod® or iPhone® through this sweet-sounding Alpine CD receiver. Just connect your player to the CDE-121's front-panel USB input, and you can use the rotary controller to search for tunes. And it's no problem if you have a lot of music — Alpine's Percentage Search lets you jump through your list quickly using the radio preset buttons.
More ways to play your music
The CDE-121 will play your CDs, plus discs you've loaded with MP3, WMA, and AAC files. You can also load your files on a USB thumb drive and pop it in the front USB input. The front auxiliary input comes in handy for connecting a Dock & Play satellite radio or another portable player.
Adding on
A set of subwoofer preamp outputs provides a convenient connection for an amp & sub combo or a powered sub, and you can use the subwoofer level control to dial in the right amount of bass. Then fine-tune your sound using the adjustable bass and treble controls. One more cool feature — this receiver works with Alpine's Power Pack, a compact box that hooks up easily to your receiver, boosting its power from 18 watts up to a serious 45 watts RMS per channel.
iPod note: If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this Alpine.
Installation Note: This receiver's preamp outputs are intended for subwoofers only. This Alpine won't work with wiring harnesses or OEM adapters that require a receiver with preamp outputs.

This was a replacement for a OEM Radio. The ease of use and sound quality was more than expected. A big tip of the hat to Crutchfield for the free items that made this a quick and easy install.
