Our take on the Sony Xplod CDX-GT450U

by Ken Nail
Sony

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.

Sony's CDX-GT450U CD receiver is all about great sound. Its powerful amp teams up with the Advanced Sound Engine — a suite of impressive controls, featuring a 7-band equalizer, low- and high-pass crossovers, Listening Position calibration, and sound-restoring DM+ circuitry for your music files. Short story — you'll have incredible control over your sound system's performance.

Plenty of listening options
Slide a thumb drive loaded with miles and miles of music into the USB slot (no iPod® control). Sony's search features will find the song you want in a hurry, with handy tools like Quick-BrowZer® that allow you to browse by artist, album, or other category. You can also plug just about any portable audio player into the front-panel auxiliary input.

Pop in your favorite CDs, including ones loaded with MP3, WMA, or AAC files. Another cool plus — the CDX-GT450U's tuner delivers Radio Data System info from participating AM or FM stations, so you'll see station call letters and song title on the display.

Want to keep your steering wheel controls?
In most vehicles, you can use an adapter to connect your vehicle's steering wheel controls to this Sony stereo. Connect a few wires, then program the adapter for your particular car and the Sony, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

    Display Features

    Detachable Face: The CDX-GT450U features a detachable face for theft prevention. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Note: No face case is included with this unit. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit.

    Caution Alarm: If you turn the ignition switch to the Off position without detaching the front-panel, the caution alarm will sound for a few seconds. The alarm will only sound if the built-in amplifier is used.

    Black 1-Line LCD Display: The Sony Xplod CDX-GT450U features a single-line black LCD with a negative display (white text) for viewing information.

    Motion Display: This feature shows moving patterns and a spectrum analyzer on the display when turned on.

    Auto Scroll: This feature allows long displayed items to scroll automatically across the display when the track is changed on a disc.

    Display Illumination/Clock Display: Pressing the Source/Off button once will switch sources. Pressing and holding the Source/Off button for one second will turn off audio output, but the clock display and button illumination remain on. To turn the unit off completely, you must press and hold the Source/Off button for two seconds.

    Dimmer: The CDX-GT450U feature a dimmer mode to dim the brightness of the display. You can choose from either "Dim On" or Dim Off".

    Auto Off: When installing in a vehicle without an accessory power wire at the radio location, you can set the unit to turn off all lighting a set amount of time after you turn the power off. The Auto Off feature can be set to 30 seconds, 30 minutes, 60 minutes, or No.

    Audio Section

    True Fidelity Sound Construction: The Sony Xplod CDX-GT450U FM/AM compact disc player features a newly developed sound processor for less distortion, an S-MOSFET IC for smooth signal transmission, and a large-sized capacitor for deep bass sound.

    Dynamic Reality Amp: The CDX-GT450U is equipped with Sony's Dynamic Reality Amp to produce 3 dimensional sound staging for more realistic sound inside your vehicle.

    24 Bit D/A Converter: The Sony CDX-GT450U utilizes a 24-bit digital to analog converter for superior CD sound quality.

    CEA2006 Compliant Amplifier: The power specifications for the Sony Xplod CDX-GT450U are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the CDX-GT450U are as follows:

    • Continuous Power Output: 17 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Peak Power Output: 52 watts x 4-channels (208 total watts)

    Two Pairs Of 2V Preamp Outputs: The CDX-GT450U contains two pairs of 2-volt RCA preamp outputs - a front pair and another pair that can be set for the rear channels or for subwoofer operation.

    Subwoofer Controls: When the unit's subwoofer output is activated, the preamp output becomes non-fading and a low pass filter is activated with a selectable cut-off frequency of 50Hz, 60Hz, 80Hz, 100Hz, 100Hz, 120Hz, or Off. You can also adjust the slope (1/2/3) of the high-pass crossover. You can adjust the subwoofer preamp output's volume level independently from the headunit's volume control from -10 to +10 in 1dB increments. In addition, you can select the phase of the subwoofer output from Normal or Reverse.

    High-Pass Filter: The front and rear speaker outputs offer a selectable high-pass crossover frequency of 50Hz, 60Hz, 80Hz, 100Hz, 100Hz, 120Hz, or Off. You can also adjust the slope (1/2/3) of the high-pass crossover.

    Advanced Sound Engine: Sony's Advanced Sound Engine creates an ideal in-car sound field with digital signal processing. Advanced Sound Engine contains the following features: EQ7, Listening Position, DM+ Advanced, Rear Bass Enhancer, and Dynamic Loudness.

    • EQ7: You can select an equalizer curve from eight music types - Xplod, Vocal, Edge, Cruise, Space, Gravity, Custom, or Off (Flat). The Custom EQ7 mode allows  you to make  your own equalizer settings. You can adjust the level (+/-6dB) of seven different frequency bands - Band1 (63Hz), Band2 (160Hz), Band3 (400Hz), Band4 (1kHz), Band5 (2.5khz), Band6 (6.3khz), and Band7 (16.0kHz).
    • Listening Position: This unit can change the localization of sound by delaying the sound output from each speaker to suit your position, and simulate a natural sound field with the feeling of being in the center of it wherever you sit in the car. You can choose from Front Right, Front Left, Front Center, or Off. You can also set the subwoofer distance of the subwoofer to Near, Normal, or Far
    • RBE (Rear Bass Enhancer): RBE enhances the bass sound by applying the low-pass filter setting to the rear speakers. This function allows the rear speakers to work as a subwoofer even if there is no subwoofer connected.
    • Dynamic Loudness: Dynamic Loudness refers to compensating for volume level and signal gain.
    • DM+ Advanced: DM+ Advanced improves digitally compressed sound by restoring high frequencies lost in the compression process (works only for USB).

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

    Radio Functions

    SSIR-EXA AM/FM Tuner with RDS: The Sony CDX-GT450U features a built-in SSIR-EXA AM/FM Tuner with RDS.

    Good Basic Radio

    Written By DougL, Atlanta, GA on Thursday, July 28, 2011
    Crutchfield Customer Review (What's this?)
     
    The Sony is what I expected. I liked the remote control, AUX input, USB connection and easy installation. The button layout is a bit cramped and small and I found I had to read the manual to set the thing up - - not overly intuitive in design. Also, I still have not found a 'tune' button to dial up a radio station. However, it did auto learn all stations and auto assigned them to the 3 memory rows in FM (18 total stations) so once I figured that out I'm happy. Manual is good, sound is good, I'd purchase again.

    This deck performs better than I expected. Amazing sound and ease of use. I am really happy with this deck and with Crutchfield. It took me some time to figure how all the wires needed to be connected. It has been about 25 years since I had installed a stereo in an automobile so I was a little concerned at first. Use of this site to make sure I had all the required parts so the features still worked in the car was amazing. Everything fit like a glove. I am impressed and I will purchase from this company again real soon. The installation instructions were easy to read and very detailed

    X-plod as a replacement

    Written By Pythor, Rockland, ME on Saturday, March 19, 2011
    Crutchfield Customer Review (What's this?)
     
    Well I was looking to upgrade my stock radio to something that played other than
    AM/FM and Cassettes. I found it. The price was right at Crutchfield and with the
    install kit as a freebie, it was a no-brainer. I literally had it in the car and running
    within 1/2 an hour. That was even after soldering all the connections and heat-
    shrink wrapping them. I use the USB connection wit a flash drive the most, but still
    hit the FM channels. Love the preset options and EQ, Position, and the Zapper!
    The only con is sometimes I hit the input button when changing the volume..
    otherwise. A great little radio with good sound at a great price.
