Our take on the Kenwood KDC-HD545U


Kenwood built the KDC-HD545U CD receiver to cover all the bases. Sure, you expect a CD player, but factor in built-in iPod® controls, an auxiliary input, and a cutting-edge HD Radio™ tuner, and you’ve got a powerful and complete package ready for your ride.

A multimedia marvel
With the KDC-HD545U’s HD Radio tuner, you can enjoy the outstanding sound quality of digital radio broadcasts, with FM that approaches the sound quality of CDs. And if your local HD Radio station employs multicasting, you’ll have the option of listening to multiple channels on the same frequency. When your iPod’s connected to the receiver, iTunes® tagging lets you save song info, so you can purchase tracks you enjoy later on iTunes — a nice bonus.

Connection and control of your iPod is a snap with this receiver. Plug into the front-panel USB input, and take command with a variety of tools, including dedicated Search and Return keys — you’ll find it easy to get to the tracks and playlists you want to hear.

You can play your store-bought and recordable CDs, including discs full of MP3, WMA and AAC files. If you’d like to expand your system, you can add a Kenwood CD changer or satellite radio, or use the front aux input for a direct audio connection from virtually any audio source.

Convenient shortcuts
The Mixed-Preset Memory feature gives you a useful one-touch shortcut to a favorite playlist, satellite radio channel, an HD Radio station, and more. Once the preset buttons are set to your choices, you’ll be able to jump from station to playlist to feature with one touch of your finger.

The sound quality story
A strong built-in amp provides plenty of power to drive your speakers, while the 24-bit digital-to-analog converter brings out every last detail in your music. Use the 3-band equalizer to tweak the highs, mids, and lows for the perfect sound curve for your car.

If your aim is maximum sound quality, you’ll appreciate the three sets of preamp outputs for connecting and controlling a full setup of external amps and subs.

Want to keep your car’s steering wheel audio controls?
In most vehicles, you can use this adapter to connect your vehicle’s steering wheel controls to this Kenwood stereo. Connect a few wires, then program the adapter for your particular car and the Kenwood, and you’ll retain the convenience of your steering wheel controls.

Note: If you’re going to use your iPod with this receiver, be sure to check “Details” for specific iPod model compatibility with this receiver or its optional iPod adapter.
