Our take on the Pioneer DEH-X6600BT

by Ken Nail
Pioneer

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.

Built-in Bluetooth®

Pioneer's DEH-X6600BT CD receiver offers the convenience and safety of built-in Bluetooth connectivity. You can answer a phone call with the push of a button, and then talk as if your caller is sitting next to you, freeing up your hands so you can concentrate on the drive. No more hassles with plugging in your music player when you get in the car — you can stream music wirelessly from compatible devices to this receiver, plus control basic functions like "track up" or "track down."

Pioneer DEH-X6600BT

The versatile DEH-X6600BT has built-in Bluetooth.

Siri Eyes Free, too

Got an iPhone® with Siri? Pioneer's DEH-X6600BT CD receiver supports Siri Eyes Free, which means you can ask Siri to make calls, select and play music, compose and hear text messages, read notifications, even use maps and get directions — all commanded by your voice through your Pioneer receiver. It's not only convenient, it can make your drive safer and more productive.

Plenty of media options

Once your iPhone's connected to the front-panel USB input, you'll be able to access your playlists with the Pioneer's controls. And you'll also enjoy control over your favorite Pandora® stations from the receiver. You can use the USB input to tap into the music files stored on many Android devices, while the front aux input handles just about any other audio source.

Turn on the color

The DEH-X6600BT CD receiver spans the color spectrum with a multi-color, dual-zone display that lets you choose from thousands of colors for the display and controls — you can even choose different colors for each. MIXTRAX adds to the fun by adding transitions between songs along with a light show that pulses and changes color with the beat of the music. It's like driving with your own DJ.

Tailor the sound

Pioneer's potent MOSFET amplifier delivers plenty of power, while the 5-band EQ lets you tweak the sound as much as you want. Two pairs of preamp outputs make it easier to add external amplifiers or a powered sub.

Want to keep your steering wheel controls?

In most vehicles you can use an adapter (not included) to connect your vehicle's steering wheel controls to this Pioneer stereo. Connect a few wires, then program the adapter for your particular car and the Pioneer, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

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.

    Built-in Bluetooth

    Bluetooth Technology: The DEH-X6600BT is equipped with built-in Bluetooth ver. 3.0, allowing you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your smartphone to the head unit.  In order to use Bluetooth wireless technology, your phone must also be Bluetooth compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

    • Hands-Free Communication: HFP (Hands Free Profile), HSP (Head Set Profile), OPP (Object Push Profile), PBAB (Phone Book Access Profile).
    • Audio Streaming: A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile).
    Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Pioneer DEH-X6600BT.

    SPP + USB Pairing w/ Guest Mode: With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the DEH-X6600BT without having to enter pin codes or go through complicated settings (your phone must also support SSP). When your paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. Up to 3 Bluetooth-compatible devices can be paired to this head unit, but nly one device can be used at a time. You can also pair your Apple iPhone by simply connecting it to the Pioneer head unit via USB and following a single prompt on the head unit's display. In addition, the DEH-X6600BT features "Guest Mode", which allows you to add and replace a mobile device instantly to the receiver. Guest Mode is a great feature for a family vehicle with multiple drivers or a driver with multiple devices because it allows users to pair and delete devices easily without a lengthy registration or deletion process.

    Hands-Free Communication (w/ External Mic): The DEH-X6600BT supports wireless hands-free communication (HFP/HSP/OPP/PBAB) for your Bluetooth enabled mobile phone. The head unit will display the caller's information and an audible ring tone will be heard through your vehicle's speaker during an incoming call. You can manually answer an incoming call or have the unit automatically answer the call. The DEH-X6600BT allows you to carry on a phone conversation from your Bluetooth enabled mobile phone using the head unit's external microphone and your car audio speakers. During a conversation you can adjust the volume, as well as switch between the Private Mode (talking directly on your cell phone) and the Hands Free Mode. Using the DEH-X6600BT, you can dial a phone number in one of the following ways:

    • Phone Book: The phone book in your Bluetooth enabled cellular phone will be transferred automatically when the phone is paired to this unit. After finding the number you want to call in the phone book from the head unit, you can select the entry and make the call. If a lot of numbers are registered in the phone book, you can search for a phone number by the contact person's name alphabetically (A-Z).
    • Call Log: The most recent calls dialed, received, and missed are stored in memory. You can browse them and call numbers from these lists.
    • Voice Dialing (Siri only): When paired and connected with an iPhone 4S or 5/5C/5S via Bluetooth, the Pioneer head unit has the ability to access Siri through its front-panel controls and external microphone. You'll be able to dial a phone number or contact via voice command.
    Note: The external microphone provides better performance in noisy environments than the integrated microphone found on the front-panel of many aftermarket or factory radios. The microphone features a 13' cord that plugs into the back of the radio, and comes with an adjustable visor-mount clip. The microphone measures 0.475" (diameter) x 1.445" (depth). The unit is not equipped with an integrated microphone.

    Wireless Audio Streaming (with Song/Artist Info): The Pioneer DEH-X6600BT also supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth enabled audio player or smartphone. The head unit can stream music stored on your Bluetooth enabled device or music apps you have downloaded on your device. The DEH-X6600BT will be able to control basic playback features; Play, Pause, & Skip Tracks (app must also support). The head unit will also display your  music's song information; such as Artist name and Song/Album title (app must also support). When an incoming call or outgoing call is in progress from your Bluetooth enabled mobile phone, audio streaming will be paused so you can take your call.

    Auxiliary Input: The DEH-X6600BT is equipped with a front-panel 3.5mm stereo minijack auxiliary input for connecting external components, such as a portable MP3 player. 

    AM/FM + Pandora Radio

    Supertuner IIID AM/FM Tuner: The Supertuner IIID features Feed Forward Control, which avoids multi-path interference. This pre-detection of interference enables quick filter control and results in less distortion. In addition, the Supertuner IIID creates enhanced stereo during multi-path interference, unlike conventional tuners that collapse to mono. Digital processing reduces distortion, and improves Signal-to-Noise Ratio and stereo separation. Advanced analog technology improves signal processing sensitivity.

    • RDS: The Radio Data System (RDS) feature displays radio broadcast information such as artist, title, and album when listening to compatible AM/FM stations.
    • BSM (Best Stations Memory): The BSM (Best Stations Memory) function lets you automatically store the six strongest stations under preset buttons 1-6 of the currently tuned band. The tuner has 3 FM banks and 1 AM bank. You can store 6 presets for each bank giving you a total of 18 FM presets and 6 AM presets.
    • Local Tuning: Local seek tuning lets you tune in only those radio stations with sufficiently strong signals for good reception. There are 4 levels of sensitivity for FM and two levels for AM. The higher settings allow reception of only the strongest stations, while lower settings let you receive progressively weaker stations.

    Pandora Internet Radio (for iPhone & Android): The free Pandora App (either from iTunes Apps or Google Play) lets you play music from the Pandora music service through the Pioneer DEH-X6600BT using your USB-connected Apple iPhone (iOS 5.0+) or Bluetooth paired Android smartphone. Your Apple iPhone must be connected to the DEH-X6600BT via the appropriate Pioneer iPod connector cable (130CDIU51/130CDIU52, sold separately) or the connector-cable that came with your iPhone. Your Android smartphone must support A2DP/AVRCP/SPP Bluetooth profiles and be paired with the Pioneer DEH-X6600BT. Your iPhone or Android smartphone will also need an active Data Plan account with connection to the Internet via 3G, EDGE, or WiFi. The DEH-X6600BT provides control over the Pandora music service and displays Artist, Album, and Song information.

    • Station List: You can select Pandora stations from your Station List by date or alphabetically (A-Z).
    • Shuffle Station List: You can listen to songs played randomly from various stations within your Station List.
    • New Stations: New stations can be created based on the current songs or artists playing.
    • Skip Songs: You can skip song tracks within a station. You cannot skip back to a previous song. Pandora limits the number of skips allowed.
    • Thumbs Up/Down: You can give songs a thumbs up or thumbs down to help Pandora personalize stations to suit your preferences.
    • Bookmarking: The song/artist currently being played can be bookmarked & stored in your Pandora account.

    Note: Access to the Pandora service will depend on the availability of a cellular and/or WiFi network for purposes of allowing your iPhone or smartphone to connect to the Internet. Pandora is not supported in Canada and only available in the United States.

    Audio Section

    24 Bit D/A Converter: The Pioneer in-dash head unit utilizes a 24-bit digital to analog converter for superior sound quality.

    MOSFET Amplifier: The DEH-X6600BT 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 specifications for the DEH-X6600BT 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.

    • CEA2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)
    • Maximum Power Output: 50 watts x 4 channels
    Note: The rear speaker outputs can be set to provide full range output with full fading capability, or they can be set to provide non-fading subwoofer (low-pass) output. When the rear speaker outputs are set to subwoofer mode, the rear preamp outputs also switch from full range to subwoofer outputs. When set for subwoofer operation, you can connect the rear speaker leads directly to two small 4-ohm passive subwoofers or a dual voice coil sub with 4-ohm voice coils. If you prefer to use a single 2-ohm subwoofer, you can connect the woofer to one set of speaker leads, leaving the other set of rear leads disconnected. The maximum output provided when a 2-ohm load is connected to one set of leads is 70 watts.

    4ch/2V Preamp Outputs: The Pioneer DEH-X6600BT features two pair of 2.0-volt preamp outputs. The unit's rear preamp outputs can be configured as fading rear-channel outputs or a non-fading subwoofer outputs with a low-pass filter, phase adjustment, and output level control.

    Subwoofer Control: When the head unit's preamp output is configured as a subwoofer output, you can select the frequency of the low pass filter (50Hz, 63Hz, 80Hz, 100Hz, or 125 Hz), select the filter slope (-6/-12dB), select the subwoofer phase (normal/reverse), and the subwoofer gain (+6 to -24).

    Equalizer: The Pioneer DEH-X6600BT features a Preset & Custom EQ. The built-in equalizer offers 7 preset sound modes (Powerful, Dynamic, Vocal, Natural, Custom 1, Custom 2, and Flat) suitable for the music genre of your choice. The two Custom modes allow you to manually adjust the head unit's 5-band EQ (80Hz, 250Hz, 800Hz, 2.5kHz, 8kHz) from +/-6dB. Custom 1 can be set separately for each source (except for USB/iPod/Pandora); while Custom 2 and the other 5 presets are shared settings used for all sources.

    High-Pass Crossover: When you don't want low-frequency sound to be heard through your front or rear speakers, you can simply active the head unit's HPF (high pass filter). By activating the HPF, only frequencies higher than those in the selected range are output from the front or rear speakers. The high pass filter crossover can be set to 50Hz, 63Hz, 80Hz, 100Hz, 125Hz, 160hz, 200Hz or Off. The slope level of the HPF can also be adjusted to -6dB or 12dB.

    Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. Hear the detail, warmth, and clarity, the way the artist intended it, from all of your highly compressed MP3 and WMA files stored on your USB device, iPod/iPhone, and portable media players. By restoring data (especially higher frequencies) that tends to get lost in the digital compression process, Pioneer's Advanced Sound Retriever technology enhances audio reproduction nearly all the way up to 20 kHz frequencies

    Audio Level Settings: The Pioneer DEH-X6600BT CD receiver offers a variety of audio settings to tailor the bass, treble, and volume level to your preference.

    • Bass Boost The DEH-X6600BT features a bass boost function which can be used to enhance low-frequency bass sound. The bass boost function can be set between 0-6.
    • Loudness: The Loudness feature compensates for deficiencies in the low and high sound ranges at low volume. You can set the Loudness feature to Low, Mid, High, or Off.
    • Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the volume level of the FM tuner, which remains unchanged. Each source can be independently adjusted from -4dB to +4dB.

    MIXTRAX: Drawing from Pioneer's rich DJ heritage and passion for music, MIXTRAX delivers a unique DJ infused listening experience to listeners in the car. MIXTRAX is an innovative Pioneer technology that creates a non-stop mix of your music library complete with a range of DJ-inspired effects. MIXTRAX takes your typical music listening experience and creates a non-stop mix of your music with 9 random DJ effects and transitions, by removing the breaks and pauses normally introduced between tracks and replacing them with various beats. MIXTRAX is compatible with USB-connected iPhone, iPod, USB MSC device, and select Android devices. There is also a Short Playback option which limits the amount of time each track plays; select from 1, 1.5, 2, 2.5, or 3 minutes.

    Note: The MIXTRAX function does not work in App mode or with the Pandora App for iPod/iPhone/iPad. It is also not supported by USB MTP devices.

    Display Features

    Detachable Face Security: The Pioneer DEH-X6600BT in-dash CD receiver features detachable face security. No face case is included with this unit. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Color Customization: Color Customization lets the user match their receiver illumination to their vehicle's interior lighting. Over 210,000 colors are available to match the illumination of almost any car. The button illumination and display illumination colors can be customized separately for an endless number of color combinations. You can select from 5 preset colors (White/Red/Amber/Green/Blue), customize an illumination color (by adjusting Red/Blue/Green brightness levels), or scan through a variety of colors.

    MIXTRAX Illumination: MIXTRAX features a club-style illumination that enhances the mood with a dynamic dance club-like lighting effect. As MIXTRAX begins, lights start pulsing to the beat of the music, adding an extra level of entertainment. You can choose among twelve patterns of lighting variations from sound pressure level or low-pass synchronization modes. The lighting effects work like a spectrum analyzer, reaching peak colors based on the intensity of the music. You can also choose which area's of the head unit's face illuminates; select Display, Display/Buttons, or Off.

    Display Illumination/Clock Display: When the Clock Display has been turned on, pressing and holding the "SRC" button turns off audio output, but the clock display and button illumination remains on (you can press the "DISP" button to turn off). When the Clock Display has been turned off, pressing and holding the "SRC" button turns the unit off completely. Even if you have turned the radio completely off you can view the clock display by pressing the "DISP" button. The clock will then remain On until you turn it back Off. When the unit is On, you can select between the clock display or the audio track/tuner display.

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

    Remote Control

    Wireless Remote Control: The DEH-X6600BT comes with an IR wireless remote control. The remote allows you to control the volume, switch between sources, pause the CD, change the display, and adjust the audio. You can also mute the volume (function that cannot be performed from the front panel). In addition, you can answer/end calls from a Bluetooth connected smartphone.

    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.

    Good basic unit

    Written By Kevin M, Reno, NV on Sunday, July 27, 2014

    Not a bad unit for what I needed it for. I installed it in my 1993 Suburban for road trips out of town for camping, hiking, etc. I easily connected my Galaxy S4 via bluetooth, and it does a great job of streaming music that way. I haven't yet used the aux or Pandora apps, but they are standardized. The radio reception was pretty good. I can't comment on the sound quality much- the speakers are original except for some cheap Kicker 4x6 on the dash to replace failed originals. The sound quality was fine, but there is little to no low end frm my speaker setup right now.
    Pros:
    Inexpensive, does hands-free calling, streams music viz Bluetooth. Great value if you don't want or need GPS or video.
    Cons:
    It lacks features of more high-end units, but again, it's cheap. Some of the menus can be difficult to figure out, like sound balance and display options, but a little patience and I had it figured out.

    Great head unit for a great price

    Written By Sjanderson, Kirkland, WA on Friday, July 18, 2014
    Crutchfield Customer Review (What's this?)
     
    I upgraded from the stock stereo in my 2005 Subaru Outback and noticed a HUGE improvement in sound quality. The stock stereo was really terrible. This head unit added a much more powerful amplifier and versatile connectivity. It easily doubled the sound quality out of the stock speakers. While the user interface has a bit of a learning curve and isn't always as easy to use as I would like, you get used to it over time. The custom LED colors allow you to match the rest of your dash lights for a more stock appearance, which is a nice touch. The handsfree calling is hit or miss. Sometimes the person on the other end complains that my voice is very quiet and they can barely hear me. I mounted the mic on the steering column so it is pretty direct. I think the issue may be with my phone software or bluetooth. There are plenty of EQ options and ways to get more bass response. The bass booster function works well, but the Loudness setting seems to cause too much distortion through the stock speakers. I'm sure it would provide a much better punch with aftermarket speakers. Overall this is a great value Crutchfield included the wiring harness and mounting hardware, which matches the dash perfectly. Very happy with this purchase!
    Pros:
    Good sound, LED customization, bluetooth connectivity, plenty of EQ settings, amazing value
    Cons:
    User interface takes getting used to, Handsfree calling doesn't always work well, Display can be difficult to read when it is really sunny even with the brightness turned up

    I purchased this primarily for the blue tooth feature. It is excellent the remote mic makes the sound quality just as good as talking on the cell phone. The ability to talk hands free using SIRI is great. What I didn't expect was the great sound quality including the super low bass feature. The only negative I find is the display brightness is hard to see on a sunny day.
    Pros:
    Great sound. Excellent blue tooth and streaming audio.
    Cons:
    Display brightness

    Bought this for Mom, she just got an iPod and wanted a way to listen to it over her car stereo. Didn't want to mess with any adapters, wanted a clean looking install so I just swapped out her factory stereo with this Pioneer unit. Looks great, sounds great, and mom is happy because she can play her iPod in the car! Bluetooth sounds good, too. Welcome to 21st century Mom!
    Pros:
    Pioneer always builds a quality product, good value.
    Cons:
    On the highest brightness level display is hard to read in bright sunlight

    I bought my wife and I receivers for both of our vehicles because I wanted to be able stream our music collections thru bluetooth. She has an android and I use apple products, Crutchfield made the research easy to make sure both phones would work and after driving to florida this unit worked flawlessly. My only complaint was really an assumption I made about the color changing display, i figured i could pick my color but it simply rolls thru all available colors which can make it hard to see in daylight.
    Pros:
    Price, well made, install kits worked perfectly and they were free!
    Cons:
    Rolling color display(not selectable) difficult to see display during the day for half the colors(reds)
