Our take on the Kenwood Excelon KDC-X598

by Dave Delamere
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.

Kenwood Excelon quality

If you're into sound quality in your car, Kenwood Excelon receivers feature hot 4-volt preamp outputs for your amps and an impressive array of sound-sculpting tools. This Kenwood Excelon KDC-X598 CD receiver uses built-in Bluetooth® to bring hands-free calling and audio streaming to your vehicle. And Kenwood backs up this versatile receiver with a 2-year warranty.

Bluetooth lets you concentrate on driving

Bluetooth gives you hands-free calling convenience, plus a wireless connection to the songs stored on your compatible music player. If you're an Android® user who's grown tired of your old radio's complicated Bluetooth pairing issues, this receiver's simple, secure pairing (SSP) technology will make your life easier. If you're an iPhone® aficionado, the KDC-X598 gives you full Siri Eyes Free control with compatible iPhones.

Once you're paired up, you can talk hands-free by simply touching the dedicated "phone" button when a call comes in. And the receiver can alert you when you receive text messages, which you can read when you're out of the car. You can install the external Bluetooth microphone in a good spot inside your vehicle for superior hands-free communication.

Kenwood KDC-X598 CD receiver

Stream radio from your phone

If you listen to Internet radio on your iPhone or Android, you can use this receiver's controls to play music from Pandora® and iHeartRadio® Internet radio. You can scroll through your stations, bookmark songs, and give a thumbs-up or thumbs-down right from the receiver's face. And speaking of radio, you can add a satellite radio tuner to this Kenwood, and get into the in-depth music and entertainment programming provided by SiriusXM.

The sound and the display

The KDC-X598's 3-band parametric equalizer lets you adjust the centerpoint of your treble, midrange, and bass controls. You can use the low-pass frequency filter and phase control to tune the bass going to your subwoofer. You can also adjust the variable-color display so this Kenwood looks right at home in your dash, while dust covers protect the CD slot, aux input, and USB port.

One versatile USB port

The receiver's front-panel USB port allows you to access and control the music stored on your iPhone or Android phone. And the port can handle MP3, WMA, or WAV music files on a thumb drive too. Here's a nice feature from Kenwood — Drive Change allows you to connect a memory card reader or USB hub to the Kenwood's USB input and select music from up to five memory cards or USB flash drives.

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 Excelon stereo. Connect a few wires, program the adapter for your car and this Kenwood, 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.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

    Audio Section

    Excelon Series: The KDC-X598 CD receiver is part of Kenwood's Excelon series line-up. It incorporates the latest technologies and delivers the highest sonic performance. From advanced audio tuning capabilities, crossover and equalizer system, high-voltage preouts (4V), plus a two-year warranty - Kenwood Excelon represents exceptional audio quality with long-lasting dependability.

    16 Bit D/A Converter: The Kenwood KDC-X598 utilizes a 16-bit digital to analog converter for superior sound quality.

    MOSFET Amplifier: The Kenwood KDC-X598 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-X598 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

    6ch/4V Preamp Outputs + Sub Control: The KDC-X598 features front, rear and subwoofer 4.0-volt preamp outputs. The front and rear speaker preamp outputs are balance and fade adjustable. The subwoofer preamp output is non-fading. The Kenwood KDC-X598 offers the following subwoofer controls, when you are using unit's subwoofer preamp output.

    • 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.

    Front & Rear High-Pass Filter: The KDC-X598 features a 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.

    Speaker Settings: The Speaker Setting function tailors the head unit's audio 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).

    EQ Pro: The KDC-X598 is equipped with Kenwood's EQ Pro. The integrated equalizer offers 8 preset sound modes (Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User) suitable for the music genre of your choice. The Drive EQ mode is an EQ preset that helps reduce road noise. The User mode allows you to manually adjust the head unit's 3-band parametric EQ (Frequency, Level, and Q-Factor).

    EQ Pro
    Frequency Level Q
    Bass 60, 80, 100, 200 Hz -8 to +8 1.0, 1.25, 1.5, 2.0
    Midrange 0.5, 1.0, 1.5, 2.5 kHz -8 to +8 0.75, 1.0, 1.25
    Treble 10.0, 12.5, 15.0, 17.5 kHz -8 to +8 Fixed
    Note: You can store EQ Pro bass, middle and treble tone settings for each source (Disc, Tuner, Aux, USB, iPod, and Pandora/iHeart Radio).

    Sound Enhancements: The head unit provides further sound enhancements for your car audio system.

    • Bass Boost: The Kenwood CD receiver features a Bass Boost control that can be set to the following levels (BB1, BB2, BB3, 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).
    • Sound Reconstruction: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Sound Reconstruction 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 Sound Reconstruction is Off, the unit plays the original sound stored in the audio file.

    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).

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

    Built-in Bluetooth

    Bluetooth Technology: The Kenwood KDC-X598 is equipped with built-in Bluetooth (ver. 2.1 + EDR) 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 1.5 (Hands Free Profile), OPP 1.1 (Object Push Profile), PBAB 1.0 (Phone Book Access Profile).
    • Audio Streaming: A2DP 1.2 (Advanced Audio Distribution Profile), AVRCP 1.3 (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 Kenwood KDC-X598. Visit Kenwood's Support Site for a complete list of compatible Bluetooth enabled phones.

    Secure Simple Pairing (SSP) + Auto Pairing (for iPhone): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the Kenwood KDC-X598 without having to enter pin codes or go through complicated settings. When a paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. You can pair up to five Bluetooth-enabled devices to the Kenwood head unit with a maximum of two Bluetooth phones and one Bluetooth audio player connected at one time (but only one can be used at a time). You can even pair your Apple iPhone by simply connecting it to the Kenwood head unit via USB and following a single prompt on the head unit's display.

    Hands-Free Communication w/ External Mic: The head unit supports Bluetooth hands-free communication for your Bluetooth enabled mobile phone. The controls of the KDC-X598 can be used to dial a number, answer an in-coming call, or end a call. The unit also includes an external microphone (featuring adjustable gain), so you can carry on your side of the conversation while listening to the caller through your vehicles speakers. During a conversation, you can switch between the Private Mode (talking directly on your cell phone) and the Hands Free Mode.

    • Answering a Call: When a call comes in, a ring-tone will be heard through your vehicle's speaker and the caller's name or phone number will be displayed. You can answer the call from the head unit's front-panel controls, or setup the head unit to automatically answer the incoming call immediately or after 1-30 seconds. The KDC-X598 also supports the Call Waiting function, so you can answer another incoming call while suspending the current call you are on. Your compatible cell-phone must also support this feature.
    • Dialing a Number: Using the KDC-X598, you can dial a phone number in one of the following ways:
      • Entering a Phone Number: Allows you to directly dial a phone number up to 32 digits from the head unit's control knob or remote control.

      • Phone Book: You can dial by using the downloaded phone book. You can download phone book data from your cell phone to the KDC-X598. Up to 600 numbers can be stored for each registered cell phone. Each number can be up to 32 digits long and each name can be up to 50 characters long. Stored phone numbers can be categorized by General, Home, Office, Mobile, or Other. You can search each category of the phone book in alphabetical order.
      • Call History: The Call History is a list of calls that have originated from and were received by this unit that you can dial. You can select Outgoing, Incoming, or Missed calls.
      • Voice Dialing: If your mobile phone supports voice recognition, then you can dial out by voice command. Simply speak into the included microphone.

    Note: The external wired microphone offers improved audio quality versus an integrated microphone, so you can be heard easier over noisy traffic and road noise. You can adjust the volume level and noise cancellation of the microphone without affecting the other sources. The external microphone features an attached 10' cable terminated by a right-angle 3.5mm connector which plugs into the mic input on the rear-panel of the head unit. The microphone offers an integrated mounting bracket which can be clipped to your vehicle's sun-visor or taped to your dash. The external microphone measures 0.525" (diameter) x 1.505" (depth).

    SMS: If your Bluetooth enabled mobile phone is compatible with SMS (Short Message Service), the Kenwood head unit will notify you when a message has been received. You must then use your phone to check the message. You cannot read, edit, or send a message through this unit.

    Wireless Audio Streaming (w/ Metadata Display): The Kenwood KDC-X598 also supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth enabled audio player or smartphone. The KDC-X598 will be able to control basic playback functions of your Bluetooth device's stored music; such as Play/Pause, Skip Next/Previous, Fast Forward/Rewind and Random/Repeat. The head unit will also display your stored music's song information; such as Artist name and Song/Album title. The KDC-X598 also supports audio streaming of music apps downloaded on your smartphone with metadata display and limited control. Advanced music control of your music apps will still need be done via your Bluetooth-enabled smartphone. 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. Once the call is finished, your streaming music will resume.

    Siri Eyes Free Control: When paired and connected with an iPhone 4S or 5/5C/5S via Bluetooth (not USB), the Kenwood KDC-BT858 has the ability to access Siri through its front-panel controls and external microphone. Simply press-and-hold down on the head unit's Answer Button to engage Siri and use the included microphone to communicate with Siri. Siri's voice will heard through your vehicle's speakers. All Siri functions including hands-free calling, music search, setting reminders, text-messaging, audible navigation, and more can be done through the KDC-X598 and its microphone. The head unit's display will only indicate hands-free calling and Bluetooth audio information (all other functions of Siri are only audible through the Kenwood KDC-X598; visual data will still need to be viewed from your iPhone device).

    Note: You can ask Siri to get directions to a destination and the turn-by-turn instructions will heard through your vehicle's speakers, while the on-screen map still displays on your iPhone 4S/5/5C/5S. The head unit's audio is attenuated while Siri provides audible directions.

    Music Control for Android Smartphone: The Kenwood Music Control app for Android organizes your Android smartphone's music, while providing quick and easy search capability from the Kenwood CD receiver. The free Kenwood Music Control App for Android can be downloaded onto your Android smartphone from the Google Play App Store. Your Android smartphone must be running Android OS Froyo or Gingerbread (2.2+). Once the app is downloaded and has a chance to organize all the stored music on your Android smartphone, you can connect your Android smartphone to the Kenwood CD receiver via USB (your compatible Android smartphone must be recognized as a USB mass storage class device; not compatible with MTP protocol). The Kenwood Music Control app offers the following Android supported functions.

    • Song Management: Music stored in your Android smartphone can be navigated from the Kenwood CD receiver. Songs can be easily selected by searching for a Song title, Artist name, Album label, or Genre.
    • Song Information Display: Song information such as Artist name, Song title, and Album label are displayed on the connected Kenwood CD receiver.
    • Mood Playlist: Playlists can be created by classifying songs into categories by type of mood. Songs are analyzed and classified into the following categories of moods - High Energy (Active/Powerful/Core), Acoustic (Detailed/Simple/Smooth/Easy), Standard (Dynamic/Rockin/Vivid), Stylistic (Cool/Urban/Trance)
    • Intro Skip: This function allows you to choose and listen to only the hook-lines of songs stored in your Android smartphone.
    Note: When the Kenwood Music Control app is first downloaded it will require some time to populate all the music, so we suggest doing this overnight.

    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 head unit allows you to select the source type displayed when using the auxiliary input. You can choose from AUX, DVD, Portable, Game, Video, or TV. The unit has three aux input modes.

    AM/FM+Internet+SiriusXM Radio

    RDS AM/FM Tuner: The Kenwood KDC-358U features a built-in RDS AM/FM tuner. The Radio Data System (RDS) feature displays radio broadcast information such as artist & track information when listening to compatible AM/FM stations. 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), or Manual Tune. The KDC-358U's tuner features 3 FM banks (1, 2, 3) and 1 AM bank for storing presets. The Kenwood KDC-358U 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.
    Note: 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.

    Internet Radio Apps: The Kenwood KDC-X598 allows you to access Pandora and iHeartRadio online music services through your USB-connected iPhone or Bluetooth-connected Android/Blackberry smartphone. Your Apple iPhone must be connected to the KDC-X598 via the Kenwood KCA-iP102 cable (sold separately, or the cable supplied with your iPhone.

    Decent radio except the bluetooth option which is the main reason for purchasing the radio. Keeps dropping the connection to the android phone it is paired with. Requires a manual connection each time. Not safer than talkingon a phone while holding it to your head:(

    Overall a good unit. Lots of bells & whistles. would buy again
    Pros:
    Hands free works well. USB is great. Sound quality is excellent
    Cons:
    Display is too dim to see well in daylight. Pain in the butt to have to scroll through all of the functions to go to standby. Kenwood's music system for the USB is not very flexible and is hard to set up playlists.

    This radio only plays Bluetooth out of the front speakers for some reason while every other setting does all speakers, the brightness of the screen isn't good at all even with the settings put all the way up, if the suns shinning good luck reading your deck. The appearance looks nice though.... Volume at the highest (35) is horrible... I bought 4 3ways to go along with it and they sound distorted when I turn the volume up when the Crutchfield rep told me they would slam, very disappointed !!! More than likely I will go to my local audio store from now on
    Pros:
    Looks cool Easy install
    Cons:
    Sound is distorted Bluetooth only works on front speakers while other sources play all 4. Screen brightness is horrible.. Hope you only use at night.
    Crutchfield response on Tuesday, August 19, 2014
    The problem with Bluetooth audio only playing up front can be fixed by changing a setting in the setup menu. Check your owner's manual for instructions, or contact our Tech Support team. They can also give you some insight on adjusting the sound settings to make the speakers sound better. That Kenwood has a great set of tools for tuning the sound.

    Crutchfield Customer Review (What's this?)
     
    2 major issues: the display isn't very bright (even with the "dimmer" off and brightness turned all the way up) and thus is very hard to read during the day (at night it's fine), and I've also experienced significant Bluetooth issues (randomly disconnecting, not remembering or auto-connecting previously connected devices, etc). Other than that, this unit functions well.
    Pros:
    Good value, sound quality, etc
    Cons:
    Display brightness, Bluetooth issues/problems

    Written By Bartfast, Dubuque, IA on Wednesday, August 13, 2014
    Crutchfield Customer Review (What's this?)
     
    I've installed and setup other brands, but Kenwood is my go- to brand for my own rigs because of their quality and value. You simply won't find another player at this price point with this many solid features.

    My only serious complaint about this model is it's display visibility. If you set the color and brightness just right you -can- read it, but I've found that the real problem is glare - the face is curved, and so shiny it reflects like a funhouse mirror. I've thought about getting an anti-glare smartphone protector to trim and cover the screen to see if that helps.

    The sound output of this thing is great; better even than other excelon players I've seen. Unless you upgrade to something with a 5 or 7 band eq, you're not going to get more customization than this, and the internal amp performs way above its pay grade.

    I bought two of these, one for my car and for my wife's. We both primarily use the BT audio. They connect up and play wonderfully with her iPhone and my HTC One. It also works with my wife's no-name android tablet. In my car I'm using Excelon 6x9/6.75's and its pure bliss, and even the oem speakers in my wife's caravan sound decent with this player.

    This player is firmware upgradable, ours both shipped with the most recent version, (June 2014) It's worth considering this when reading reviews about compatibility issues. Crutchfield's research tab has good, detailed info about how this will work for you.
    Pros:
    High quality sound. Excelon features give lots of control over sound. Compatible with all my devices. Menus are easy to learn/use. Nice remote control.
    Cons:
    Display nearly impossible to read in full sunlight. (I Gave it a lower usability score because of this.) Lots of sound customization options means long setup time.

    Very nice unit. It has a lot of features and sounds great. I find the buttons are a bit small though and the display is practically useless during the day. It installed fairly easily in my honda fit but it is sitting back a little and makes the buttons a bit more difficult to access. Very intuitive, for the most part, function use.
    Pros:
    Sounds great. USB works good. Bluetooth music and phone is excellent. Microphone picks up good sound for phone use. Looks great at night!
    Cons:
    Display is useless during the day. Buttons are a little hard to access. Install is ok...radio sits back a quarter or 1/3 of an inch (i.e. not flush with the faceplate).

    Sounds great, and has more capabilities (sound/amp management) than I'll ever need. Only complaint is the lighting is too dim. The dash angle of the CRV makes face plate tilt slightly up toward the driver. Because of the gloss finish of the face plate, it catches and reflects the glare of day light. The lighting is not bright enough to over come this and is nearly impossible to see with polarized sunglasses on. Tinted windows would eliminate the glare. This head unit would not visible at all in a convertible.

    From a long time Kenwood Fan

    Written By Dan C., Virginia on Sunday, August 10, 2014
    Crutchfield Customer Review (What's this?)
     
    Background: Audio Enthusiast; Long time Kenwood User; Electrician

    Been using Kenwood Head Units all my life and still have to say that they are the best around when you take into consideration the features + sound quality + sound tweakability. I bought this head unit in order to dive into the new world of bluetooth car audio (which is great btw - no more wires or cds or usb drives + infinite music with pandora). I have a Droid 4 with an Auto Bluetooth Connection app to force the bluetooth connection to this head unit everytime I get in the car. I also have the Smart Actions set to only turn the bluetooth on during the times of day I am in the car.

    In my opinion this headunit is a huge step down from their previous products. You'd think time would make products get better not worse. For this price I would expect more from Kenwood.
    Pros:
    - Bluetooth from the BT Mode works well and quickly. - The audio tweaking capabilities are still up to the Kenwood par which is what Kenwood Fans love.
    Cons:
    - Bluetooth connectivity with Pandora is horribly slow as well as iHeartRadio. Most of the time I have to manually unlock my phone and turn Pandora on. - The remote which comes with all Kenwood headunits (which has made Kenwood so great) is extremely slow and sometimes is not even detected. Idk what Kenwood changed between this version remote and the last but the response time has gone downhill quite a bit. - The screen at full brightness (full white) is extremely dim (only visible at night

    Have had this in my truck for about a month now. Sound is great when EQ adjusted properly. Had some flaky button issues with unit not wanting to skip to next song or change station but called Devin at tech support yesterday and he walked me through resetting the unit and button issues seem to have cleared up for now. Display can be difficult to see set on any of the many colors or brightness settings during daylight hours. Overall, good value and great replacement for stock unit in my truck!

    This is my first Kenwood deck, it replaced an aging Pioneer deck. I sought direct USB connectivity for thumb drives and Bluetooth hands-free abilities, but the 4V outputs and other bonus features definitely peaked my interest.

    Overall, the deck was a good choice. Immediately, I could tell a major (and I mean significant!) improvement in the sonic quality over my older aftermarket deck that I probably paid twice as much for 10 years ago. After a bit of tuning, that disparity became even wider. Installation was pretty easy, the documentation relatively clear and navigation mostly intuitive. Bluetooth works great, audio quality is satisfactory both ways and my overall impression was money well spent.

    The display is not as bad as I thought it would be, but in direct sunlight, it's nearly impossible to read. The variable color is cool, but many are even less visible. I originally had concerns about navigating large numbers of folders on a USB stick, but it's not too bad..but it is a bit cumbersome to find one album amongst hundreds of folders on a large USB stick. (Cellular remote integration would be nice!) I also wish there were more display choices...the 1.5 lines is more like 1.25 lines, more scrolling and display outputs would be welcome. My biggest gripe, though, is that you can't do a 80Hz LPF for a sub with an equivalent HPF on the four speaker outputs, you're limited to 85/120 or 120/120...so you either send higher Hz to the subs, or you lose around 35Hz.
    Pros:
    Superb sonic quality 4V Outputs USB thumb drive compatibility Decent documentation Bluetooth handsfree / impressive integration Bluetooth radio integration Looks sharp Easily tuned Good price for features ratio Lots of options to play with
    Cons:
    Display hard to read in sunlight 1.5 display lines is somewhat limiting I expected a better display for a mid-range deck "Auto" text scroll option delays scrolling frequently Drive EQ is hard to figure out HPF/LPF aren't set where I'd like (80/80 or 85/85)

    A huge upgrade for an old truck

    Written By Daxx MC, Kansas on Saturday, July 19, 2014
    Crutchfield Customer Review (What's this?)
     
    I bought this as part of a larger upgrade for a 2002 Nissan Frontier, to replace the standard am/fm/cd player. I have used Kenwood decks in the past, and this one fit the requirements - CD player, am/fm, Pandora compatible, USB port and bluetooth hands free.

    Installation was easy with the supplied dash kit and wire harness. I took extra time to solder and heat-shrink connections. The hardest part was installing the bluetooth microphone in an unobtrusive spot. In the end, I took the a-pillar trim off and threaded it up to the top-left of the windshield. Initial EQ and display settings left something to be desired, but once I'd set the display to one color and flattened the EQ on all bands (it came set to +6dB on bass, mid and treble) it sounded pretty good through Polk door speakers and factory a-pillar tweeters.

    Paired with the truck owners Android phone over bluetooth first time, and the phone auto-connects when the vehicle is started. Call quality is good for both the caller and the driver. Pandora and bluetooth audio works well, and it will also playback Audible audiobooks from the app on the phone using the BT Audio input. I loaded a 32GB USB micro thumbdrive with 320kbps MP3 files. Searching and selecting is easy, but it's easy to get ahead of the deck when scrolling through a long list and it can take a few seconds to catch up and show names instead of numbers.
    Pros:
    Good sound though all sources. Display is informative. Was able to set white illumination to match the truck. Bluetooth call quality is very good, as is bluetooth audio streaming. Plain looks are a bonus - no chrome or other bling to call attention to itself.
    Cons:
    No illumination dimmer, and display could be brighter at times. Main control knob is slick, and can be difficult for someone with long nails to use. Out of the box EQ settings are a mess; need to set everything back to 0dB gain before listening, and do that on all sources. Need to use Kenwood Music Editor software to prepare a thumbdrive to allow searching.

    This unit is in my MS3 and it bumps on the right settings. The bluetooth is quality and does everything it's suppose to. The unit is solid . My only downfall is the way it looks is. Kind of plain in my opinion. All in all it's a good unit especially for the money
    Pros:
    Sound quality Sound quality Sound quality and Ease of installation
    Cons:
    CD flip cover it would be better without it

    This unit has it all. I can play my music in a variety of ways as well as enjoy the hands free phone feature which sounds perfect.
    Pros:
    Versatility, price, sound and looks
    Cons:
    Clock feature a bit small. A little complicated but taking the time to learn all the features is definitely worth while.

    for the money

    I have been playing with car audio for a little over 15 years now and I must say that this unit is a pretty good bang for the buck. 4v preamp outputs are a must for a 4ch amp. Plus, I personally like a separate sub preamp output and the fact that this unit allows me to set a lowpass xover that I can adjust from my driver's seat( and not having to contort myself to reach and adjust the amp under the seat). There is also an adjustable highpass xover that is pretty handy because nobody want low freqs to muddy their midrange. Setting this thing up wasn't too difficult, however, I have been doing this stuff for a while and I am very familiar with Kenwood heads and amps(don't buy their speakers, go with focal and you won't be let down!). I must add that this is the cheapest head that I have ever purchased and the only reason I did, was because it was purchased for my father's budget limited beach buggy chevy tahoe. All in all, this is a good clean signal producing head with just enough features to make a ride sound decent.
    Pros:
    good and cheap or maybe cheap but really good
    Cons:
    not any for this price point

    Pros:
    Excellent Sound Quality Multiple Bluetooth functionality Good value

    Very great sterio with awesome sound, considering I'm still using my factory speakers. Looks great in the dash and the blue tooth function works great.
    Pros:
    Blue tooth, SIRIUS XM functions. Looks,
    Cons:
    Settings can get a little tricky, and when you have more than one blue tooth device in the vehicle, it will sometimes "kick off" the device you want to use.

    I've been a fan of Kenwood a long time. I've never had any of home receivers and car receivers fail. So I figure keep with what's working. This unit was easy to install, east to initially set up, and the pairing the Bluetooth was a breeze. For $150, you get a lot of bang for your buck.
    Pros:
    Great value, easy to install, great quality, etc.
    Cons:
    None

    Very happy with this unit, coming from an Alpine head previously. I wanted something that had an intuitive user interface for my iPod as I drive in some fun traffic here in the DC metro area and was tired of changing CD as my mood changed behind the wheel. My only complaints are minor, but the same as most of the others that I've read, the screen is very difficult to read if the sun is out. I'm not sure how hard this is for the folks at Kenwood to fix, but while they are at it a knurled volume knob would be nice too.
    Pros:
    Great sound, Intuitive user interface, lots of options
    Cons:
    Panel difficult to read in sunlight.

    Best of the Best

    Written By HappyCustomer, Florence, KY on Thursday, June 26, 2014
    Crutchfield Customer Review (What's this?)
     
    This made the 14 year old speakers in my parents' Durango sound like they were top of the line speakers (I compared before and after). All of the countless features work flawlessly, and it is very easy to use once you understand how the menu system works. Even my 50+ father quickly learned how to navigate menus, change settings to his preferences, and use each input. Each input reconnects automatically when starting the car back up (even bluetooth - give it a minute to re-establish the connection!), remembering right where you were on a song and everything. Hands-Free calling (and voice commands with Siri) work like a charm! Hands down the best stereo I've used.

    As many others noted, it is difficult to see the display in the daytime, especially if it's tilted upwards toward the sunlight like it is in the Durango. To counteract this, ensure that you have your display brightness all the way up (to 31) and change the color to "User" and customize the color to be bright white (R-9, B-9, G-9). This helped a lot! It can quickly be changed back to your favorite color at night with just a few clicks.

    If you're looking for a quick and easy replacement that will play audio from any source you'd want (Bluetooth, CD, Radio, Aux, USB, iHeartRadio, Pandora, Sirius XM, etc) then this is the stereo for you! I'd also recommend giving your current speakers a chance with this radio before replacing them - like mine, this stereo may give your stock speakers a fresh breath of life!
    Pros:
    Sound Quality, Ease of Use, Features, Compatibility, Numerous Preset EQs, Hands-Free capability, 1.5 line display
    Cons:
    Slightly hard to see display during the day

    Excelon KDC-X598

    Written By MikeB, Mobile, AL on Thursday, June 19, 2014
     
    Reviewed a lot of stereo head units before deciding on this unit. It simply had all the features I needed at a price that was very reasonable. I installed this head on my sailboat and had some install questions that were fully answered by the techs at Crutchfield. The install went smoothly, the sound is crisp and clear, it's not difficult to operate. What more could you ask for.
    Pros:
    Great customer and tech support. Easy install. Excellent sound for the price.
    Cons:
    Haven't found any.

    Kenwood Excelon KDC-X598 Review

    Written By Scott, Kingsport, Tenn on Wednesday, June 18, 2014
    Crutchfield Customer Review (What's this?)
     
    This is a great system,with very good sound. I had it installed by Dashboard Audio, whom did excellent work.
    Pros:
    Didn't know it came with Blue Tooth, which works great. It arrived in just a couple of day(5 day before expected). Even though it came with wrong connections, I would buy this set again.(Last radio I got from Cruchfield was for my 1987 Escort & cost $500 in 1988 , it worked for 15 years). I expect this one to last as long.
    Cons:
    Can't see display in day light. Came with wrong mounting ass. (my was single connector & they sent a double connector.
