Our take on the Kenwood KDC-452U

by Ken Nail
Kenwood

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Brighten up your dash
Most factory-installed radios have bland, single-line displays, but media sources like Pandora® Internet radio or your iPod® pack a lot of info along with the music — song titles, artists, albums, and more. So if your car's radio doesn't give you the full picture, Kenwood's KDC-452U CD receiver features a selectable 2- or 3-line display that puts song info in front of you in large easy-to-read characters. And the display and button colors can be varied to match almost any dash lighting, so this Kenwood will look right at home.

Your music at your command
Once you've connected your iPod or iPhone® to the USB port on the front panel, you can navigate your playlists with the receiver's controls. And if you're a Pandora® fan, you can hook up your iPhone for control of your favorite stations, with thumbs-up, thumbs-down, and bookmarking. Even if you're not a smartphone user, this Kenwood does a great job of playing CDs, even discs full of music files, and you can always plug another device into the front-panel aux input. Plus, the KDC-452U will work with an outboard SiriusXM tuner to connect you to some of the best radio around.

And now there's good news for you Android fans — just download Kenwood's Music Control app, and you'll enjoy a variety of search and playback features when you plug your phone into this Kenwood's front-panel USB port.

Excellent audio controls
The KDC-452U is loaded with sound controls, starting with a 3-band equalizer. For quick tone changes, select one of the eight preset tone curves. And the Speaker Setting lets you choose from a variety of settings that will optimize receiver output to match your car's speaker settings.

Want to keep your car's steering wheel audio controls?
In most vehicles, you can use an adapter (not included) 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 this Kenwood, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

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.

    Display Features

    Detachable Face: The Kenwood KDC-452U features a single front loading CD face that detaches from the chassis to deter theft. The head unit includes a cloth pouch for storing the face-plate when detached. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Note: An optional soft face case (142DFC1X, sold separately) can also be purchased for this unit.

    Multi-Line Text Display: The 3-line full dot LCD makes it easy to navigate through your disc's music, radio presets, iPod music library, or USB content. The KDC-452U offers five different display types:

    • Type A: Displays 3 lines of text.
    • Type B: Display 2 lines of text.
    • Type C: Displays only the clock/date.
    • Type D: Displays motion graphics.
    • Type E: Display & button illumination is turned off (after 5 seconds of operation).

    Note: The Kenwood KDC-452U offers English, French, and Spanish menu text.

    Variable Color Illumination: The Kenwood KDC-452U features variable color display and button illumination. You can choose to use the same color for the LCD display and button illumination, or use a separate color for each one. You can choose from one of 24 preset colors, have the unit scan through all 24 preset colors continuously, or customize your own color (RGB; 0-9). The custom setting allows you to individually adjust the intensity of Red, Green, and Blue (from 0-9) to better match your vehicle's interior lights. The Kenwood logo and eject button remain red.

    Note: You can switch the in-dash head unit's display between a positive or negative effect. You can also adjust the display's contrast from 1-30.

    Illumination Effect: This function sets whether the head unit's key illumination color is changed in conjunction with the key-button operation.

    Dimmer: The dimmer function will dim this unit's display automatically when the vehicle light switch is turned On when you connect orange/white Illumination wire of this player. You can also choose to dim the display manually. The Kenwood logo and eject button remain the same brightness.

    Clock/Date Display: The in-dash CD receiver features a 12-hour clock and date (M/D/Y) display. You can even set times for two different cities (dual clock display).

    Display Illumination/Clock Display: When the unit is in Standby mode, the face and button illumination is "keyed." When the Clock Display is turned on and the unit is in Standby mode, the Clock Display is also "keyed." Pressing and holding the source button turns the unit off completely.

    Demo Mode: This unit features a Demo mode which can be turned On or Off within the menu.

    AM/FM Tuner + SiriusXM Ready

    AM/FM Tuner: The Kenwood KDC-452U features a built-in AM/FM tuner. You can choose one of four tuning methods: Auto 1 (seek tuning), Auto 2 (cycles through and tunes the selected band's preset stations only with each button press), Manual Tune, or Direct Access (via remote).

    Tuner Presets: The KDC-452U's tuner features 3 FM banks (1, 2, 3) and 1 AM bank for storing presets. The Kenwood KDC-452U offers two preset modes.

    • Normal: You can store 6 presets for each AM/FM bank giving you a total of 18 FM presets and 6 AM presets (total of 24).
    • Mix: A total of 6 preset stations can be assigned to the head unit's 6 preset buttons, regardless of AM/FM band. This lets you recall a preset station without switching between bands.

    Auto Memory Tuning: Not only does the CD receiver's tuner allow you manually enter your desired presets you can choose to have the unit automatically put stations with good reception in the memory banks automatically; this is a handy feature when traveling.

    Direct Access Tuning: You can directly access an AM/FM station by entering in the frequency number using the include wireless remote control.

    Mono Mode: The Mono mode improves the radio's FM reception, but the stereo effect will be lost.

Using either cable allows audio playback, music navigation, information display, and charging of select iPod/iPhone models from the KDC-452U. If you have an iPod nano (7th gen), iPod touch (5th gen), or iPhone 5; use the Lighting-to-USB cable that came with your Apple device to connect to the head unit.

    iPod DAC Bypass: The USB connection allows your iPod/iPhone's large music libraries to be loaded instantly to the head unit and sound quality to be maximized through the head unit's 24-bit D/A converter, allowing for a Signal to Noise ratio up to 105dB.

The USB port enables connection and control of a portable USB mass-storage class (MSC) device with MP3 (8-320 kbps), WMA (32-192 kbps), and AAC (8-320 kbps) music files. The USB port is compatible with USB mass storage class devices that support the FAT16 or FAT32 file system. Your USB device should only have a maximum of 8 folder layers, 255 folders, and 255 files per folder - with a maximum of 65,025 files and folders. USB portable audio players that can be charged via USB will be charged when plugged into the CD receiver's USB port (max. 1A), and the vehicle's ignition switch is set to ACC or On.

    Note: You cannot connect a USB device via a USB hub or Multi-Card Reader to this unit.

    Music Editor Compatible: The Kenwood KDC-452U supports the PC application, Kenwood Music Editor Lite (ver.1.1.0). Kenwood Music Editor Lite is a Windows-based desktop software that helps organize, manage and transfer MP3/WMA music files to your USB (MSC) devices from your PC.

    • Windows XP Professional, Home Edition SP2 or later (32-bit)

    • Windows 7 (32/64-bit)

    Note: Not compatible with Apple iPod/iPhone/iPad, Zune, or Android.

    Aux In: The unit is equipped with a front panel 3.5mm minijack auxiliary input that can be used to input audio from a portable audio source, such as a portable MP3 player. The Aux input must be turned on to function. The unit has 3 auxiliary input modes.

    • On1: Outputs the sound of the external unit connected to the Aux terminal when switched to the Aux source.
    • On2: Activates the attenuator function when turning on the power with the auxiliary source selected. This prevents the noise when no external unit is connected to the Aux terminal. Turn off the attenuator function when listening to output from an external unit.
    • Off: Disables the selection of the Aux source.

    Auxiliary Display: The KDC-452U allows you to select the source type displayed when using the auxiliary input. You can choose from AUX, DVD, Portable, Game, Video, or TV.

    Audio Section

    24 Bit D/A Converter: The Kenwood KDC-452U utilizes a 24-bit digital to analog converter for superior CD sound quality.

    MOSFET Amplifier: The Kenwood KDC-452U is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the KDC-452U are as follows:

    • Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)
    • Maximum Output Power: 50 watts x 4 channels

    7-Way Rotary Volume Control: The CD receiver uses a 7-way rotary volume control that increases and decreases the volume of the stereo from 0 to 35. The rotary knob also controls other audio settings such as Balance, Fader, Bass, Mid, Treble and preset EQ settings. In addition, the rotary knob allows you to scroll through and select your music tracks when the Music Search function is activated.

    Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0 (-8 to +8 for Aux source).

    Speaker Settings: The Speaker Setting function tailors the System Q Sound Control settings according to the type of speakers in your vehicle. You may select a Speaker Setting of 'SP-Off' (flat/off), 'SP-OEM' (for OEM factory speaker systems), 'SP-6x9/6' (for systems with 6" and 6"x9" speakers), or 'SP-5/4' (for systems with 4" and 5" speakers).

    Preset EQ: Eight EQ curves are preset into memory, allowing you to recall the best preset EQ curve for different types of music. Each preset has its own level settings for bass (100Hz), midrange (1kHz), and treble (12.5kHz). You can choose from the following preset EQ curves - Rock, Pops, Easy, Top 40, Jazz, Natural, Game, and User.

    Bass Boost: In addition, The Kenwood CD receiver features a Bass Boost control that can be set to the following levels (BB1, BB2 or Off).

    Loudness: This function enhances low and high frequencies to make the sound clearer lower volumes. There are 3 levels (LV1, LV2, or Off).

    Source Tone Memory: This feature allows you to store System Q bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB, iPod, and Pandora).

    Supreme Setting: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When the Supreme Setting is Off, the unit plays the original sound stored in the audio file.

    6ch/2.5V Preamp Outputs: The KDC-452U features front, rear and subwoofer 2.5-volt preamp outputs. The front and rear speaker preamp outputs are balance and fade adjustable. The subwoofer preamp output is non-fading. The front, rear, and subwoofer preamp outputs are fixed to the rear chassis of the head unit.

    Front & Rear High-Pass Filter: The KDC-452U features an independent High-Pass Crossover for the front & rear channels when your front & rear speakers are connected by the unit's speaker-outputs or preamp-outputs. You can adjust the high-pass crossover from "Through", 100, 120, or 150 Hz. The "Through" selection is a full-range setting. This feature is very helpful when you have smaller-type speakers in the front and larger-type speakers installed in the rear of the vehicle.

    Subwoofer Controls: The Kenwood KDC-452U offers the following subwoofer controls, when you have the unit's subwoofer preamp output activated.

    • Low Pass Filter: The receiver features a built-in Low Pass Filter control for the preamp-output, when the output is set to Subwoofer. You can select from 85 Hz, 120 Hz, 160 Hz, or off.
    • Subwoofer Phase: You can adjust the phase of the subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
    • Subwoofer Level: Once the Subwoofer preamp output is activated, you can independently control the subwoofer preamp output level (-15 to +15) from the CD receiver.

    Tel Mute: The KDC-452U features a cell-phone mute wire (tan) in its harness that when hooked up to your car's phone system mute wire will automatically mute the receiver's audio signal when a call comes in.

    Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Remote Control

    Wireless Remote Control: The KDC-452U comes with an IR remote control (RC-405) for wireless operation of the head unit. The remote will control Audio, CD, USB, and Tuner functions. It is powered by a single CR2025 3V lithium-cell battery (supplied).

    • Numeric Keypad: The wireless remote control features a numeric keypad (0-9) which allows direct track access of your music tracks & files (from CD or USB), as well as AM/FM presets.
    • Attenuator: The CD receiver features an Attenuator button on the supplied remote control that turns the volume down very quickly with one touch of the button.

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

    Pros:
    Easy to use controls, trouble free operation.

    I put this in my step daughters 01 Camry. She is a big IPod fan. She is very happy. I cannot say anything about the tuner as I installed and tested it quick then she plugged in her IPod and went off with her music blasting and a smile on her face.

    It seems to be a good head unit. The only problem I am having with it is that after 10+ hours of having the face plate removed I have to reset the unit. Have tried every thing KENWOOD support has told me to do to no avail. Even replace the wiring harness.
    Pros:
    Nice looking, easy to use
    Cons:
    Just the reset issue

    Not Better Than Most

    Written By Bob, Aurora, Illinois on Wednesday, December 26, 2012
     
    I purchased this unit for a factory replacement on my 2000 Chevrolet Blazer. I came across this model due to its price. After purchasing it due to knowing the Kenwood brand, I took a chance and purchased it through Crutchfield. Their service, info, and accessories are top notch, but when it comes to buying products, NOTHING beats physically touching and reviewing the product in your hands is worth extra money. This Kenwood radio plainly is difficult to use, lacks quality, and sounds as average as any model on the market. I DO NOT RECOMMEND buying this unit. It is simply a CD player with a radio with USB added. Nothing more.
    Pros:
    Looks good installed.
    Cons:
    Pandora - uses your phones data to get internet radio. Bluetooth - no microphone, uses your phone's speaker phone as microphone. Multi-directional main knob... Useless! No preset buttons for radio stations! Too many menus just to select options.

    Better than average.

    Written By navigator73, Bedford, Va on Monday, July 16, 2012
    Crutchfield Customer Review (What's this?)
     
    This unit was to replace a factory unit that had no iPod connectivity. The sound quality is outstanding. It is aesthetically pleasing to say the least. The only weak points are its FM sensitivity, which Crutchfield advertises as 9.3 dB, but Kenwood lists it at 11.2 dB. I'm going to side with Kenwood on this one. My factory unit actually did better to pick up some weaker stations from one of the two nearby cities, but the Kenwood is clearly weaker in this regard. I am also a bit disappointed on how cumbersome it is to go through station presets. You hit one button, wait, see your list of stations, flip thru them, then hit a button to select. It's a bit too distracting, which is not good when driving. Otherwise this is a good inexpensive option for a basic receiver that is nicely iPod friendly, and a good choice for someone in a city close to radio stations. If you're out in the boonies like me, you're a bit out of luck. And there is no real tuning knob. The main knob that can be toggled in 4 directions (don't know the technical term) can manually tune, but you have to click the toggle side to side to go up or down. I may be old school, but I like a good old fashioned knob to up and down the dial. This is a very good receiver, and I'm pretty happy with it, but it is a bit distracting to operate when driving.
    Pros:
    Sound quality, iPod compatibility, appearance
    Cons:
    Weak usable FM sensitivity, cumbersome preset station selection, no real radio tuning knob
    Crutchfield response on Wednesday, July 18, 2012
    Thanks for your review. Kenwood confirmed that the 9.3dBf figure, which is printed in the owner's manual is correct. Their online presentation is incorrect. Because factory stereos don't reproduce treble as well as aftermarket stereos, weak stations sometimes sound better (or at least seem to have less static) on factory stereos. The static that's inherent in a weak signal is in the higher frequencies and therefore it can be more noticeable on a better stereo.

    Great Purchase

    Written By Anonymous, Seattle, WA on Sunday, June 24, 2012
     
    For a first time install this was supper easy! It sounds and looks great. I am supper happy with this receiver. The IPod function is very nice and accessible you can control the IPod through the receiver. FM and AM come in supper clear. It sounds amazing even with out messing with the EQ. Also the multiple display options are a nice touch. I like the wave view! All in all this is the best receiver I have ever heard! Thank you Ryan of Crutchfield for your recommendation!
    Pros:
    Sound, Variable display colors and functions, Ease of installation, Ease of use

    Written By VICKY, Jamestown ND on Wednesday, June 13, 2012
     
    I bought this Deck to put in a buick LaSabre. Took forever to get put in because the wiring harness that came with it is just to big to fit behind the deck in the dash, I love that it changes color, but it doesn't have station buttons for the radio, and I hate where the button is to take off the faceplate. I hit it a million times trying to push the eject button, just seems like they are reversed to me.
    Pros:
    great sound quality, color changing
    Cons:
    hard to install

    Crutchfield Customer Review (What's this?)
     
    Don't buy this receiver if you intend using it as a car RADIO and want to quickly select between stations. There are no station buttons. This receiver must be intended primarily to play recorded music. I didn't look closely enough at the picture to see the lack of station selection buttons before I ordered. I mistakenly assumed all radios had them.
    Cons:
    No station buttons.
