Our take on the Kenwood Excelon KDC-X791

Don't settle for a boring, uninformative stereo. The Kenwood Excelon KDC-X791 CD receiver delivers the information you need on a 64-color, 3-line display, and the easy-to-read text renders your song and folder information brilliantly. When not viewing text, you can choose from a variety of energetic animations or calm backgrounds that won't distract while driving.

Don't settle for a boring, uninformative stereo. The Kenwood Excelon KDC-X791 CD receiver delivers the information you need on a 64-color, 3-line display, and the easy-to-read text renders your song and folder information brilliantly. When not viewing text, you can choose from a variety of energetic animations or calm backgrounds that won't distract while driving.

When you're ready to roll, fold down the faceplate, and insert a disc filled with MP3, WMA, or AAC music files. The Multi Control Wheel makes file and folder navigation simple. The strong amplifier and premium digital-to-analog converter create a forceful, yet warm sound that's full of the little details that lesser stereos miss.

High- and low-pass filters and speaker size matching features help you optimize speaker performance. Once you've set those, a 3-band parametric equalizer lets you zero in on specific areas of the treble, midrange, and bass, so you can shape the audio output to perfection.

This versatile receiver makes full use of its display capabilities, adding a unique feature that you won't find on most car stereos. Using an internal gyroscope, it can display vehicle performance specifications — like the G-force your car generates during turns and acceleration — with no special wiring or installation required.

If entertainment options rate high on your list, the KDC-X791 will control an optional Kenwood satellite radio or CD changer. You can also connect your portable music player to the stereo's rear auxiliary or USB inputs. Use those inputs to plug in an optional connecting cable for your iPod®, or add Kenwood's iPod adapter so you can save the USB and auxiliary connections for other gear.

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.

    MOSFET from Washington on 10/4/2015

    I have vsed nothing bvt Alpine heads for the last 20 years. I have always liked the qvality, bvild, and sovnd of Alpine. So a year ago I was bvilding a modest system in a vsed car I jvst bovght, a '03 Protege. I first bovght an Alpine cDA-105. Very simple, bvt 6 sets of ovtpvts as I vse three amps. The first thing I noticed was althovgh my CD's and lossless MP3's sovnded great, my other MP3's, many of which I had been listening to for years and thovght were OK, sovnded VERY constricted and "flat". I KNEW it was nothing WRONG with the Alpine, it simply did not have featvres like BBE and their Media Expander featvre I have always had in the past to enhance compressed files. So I get a new Alpine, CDA-117. This time, the problem IS with the vnit. A high pitch whine when the display is on and is apparently a failing of ALL OF THESE VNITS. There is nothing to be done says Alpine, that's jvst the way it is, "tvrn the display off to avoid the noise". GREAT. After 20 years and perhaps 8 different decks, I'm starting to be frvstrated with Alpine. So I check ovt Kenwood and Pioneer. After EXTENSIVE listneing tests, I decided on this deck. It sovnds AMAZING as many other people have said. My MP3's HAVE NEVER SOVNDED BETTER. They sovnd as if they all have been replaced by loss-less rematered copies. The sovndstage is WIDE and DEEP. Yet there is no hint of "digitial noise" or any degradation as often happens when a signal is heavily processed. Kenwood has a WINNER!!!

    Pros: Excellent SQ A WIDE degree of sovnd shaping tools. Separate x-over controls for both front AND back speakers, vnlike Alpine.

    Cons: Display can be hard to read sometimes. No time alignment A little hard to navigate at first

    Fantastic sounding unit!

    Jeff from Menifee, CA on 12/17/2008

    I purchased this unit for its expandable features (iPod, USB, etc.). It sounds absolutely amazing! Crisp, clear, and accurate. The Digital to analog converter in this unit is incredible, and processes digital media very well. My wife gave me an iPod, but I was hesitant to use it for music, as I was convinced that mp3/ AAC sound quality was sub-standard. I was quite surprised. Kenwood has done their homework on compressed music reproduction (superior digital to analog converter). This sounds so good I am in the process of transferring all my CDs to my iPod. I know that mathematically there is a difference in the signal, but my human ear cannot tell the difference. The KDCX791 is high quality, and does not disappoint. I spent lots of time playing a particularly well recorded song on CD, then on iPod, and was not able to detect any real differences. This unit sounds great all around. The only reason I will not give it 5 stars is the cumbersome time it takes to scroll to a group/ song/ album at the end of the alphabet. It would have been nice for Kenwood to program the scroll to work like the iPod, scanning quickly through the alphabet when the dial is turned fast. I have something like 20 gigs of music on my iPod, and it can be a real pain getting to ZZ top (as stated by another reviewer). Also have to agree that the manual was fairly difficult to navigate through, and the Kenwood music software was absolutely useless. For what I use it for, I love it.

    Crutchfield Customer Review (What's this?)

    I couldn't be happier with this deck. I have owned kenwoods for most of my aduly life. The only problem I had was using the music editor software, its just doesn't work. I just used Windows Media Player to rip and sync to a flash drive and it works very well. I just set up the basic menus and let it alone, the display is very clear except in direct sunlight, but thats the norm for most decks. The sound is much cleaner, thanks to the 4v pre-outs. The crossovers and sub level control allow you to tailor the sound to your taste and vehicle. Overall this is the best deck I have ever owned!!!



    Kenwood has made me a believer

    Kyle from Texas on 3/20/2008

    This is without a doubt one of the best head units I've ever owned or used. The sound quality is awesome, thanks to its wealth of sound options such as a 3-band parametric equalizer and separate high-pass filters for the front and rear speakers. Compared to Pioneers I've owned in the past, the internal amp has very little distortion and noise. The Kenwood is also very easy to use when driving, almost all of the basic functions can be performed without looking and with less than a few button pushes. Navigating through your USB drive and MP3-CDs is also very easy thanks to the rotating knob on the right, which works similar to an iPod. One thing I've noticed about the Kenwood is that it sorts the files in alphabetical order, unlike many other USB receivers I've tried. Unfortunately, there is no way to quickly change the display (Title, Artist, Clock etc.) without entering the menu where the more advanced features are. At least the menu is rather easy to navigate compared to some other head units I've used, but it does require you to take your eyes off the road. The KDC-X791's tuner picks up weak and distant stations just as well as the Pioneers I've owned before, but it doesn't seem to "hold on" to them as well while driving. Some of the KDC-X791's cool features are Dual-Zone Audio and the G-Analyzer. The Dual-Zone Audio, which allows to listen to the auxiliary input over one pair of speakers while you listen to another source over another pair, is really useful if you often have backseat drivers that want to listen to something else. The G-Analyzer, which tells you how aggressively you are cornering, braking, and accelerating, isn't really useful for most people, but is great for impressing friends. The head unit looks great in my dash day and night, believe me, the pictures here don't do the KDC-X791 any justice. The only thing I don't like about this head unit is the display, it is very bland and is hard to read in sunlight. It also would've been nice if "HD Radio" hadn't been printed over the display as well.

    sounds good - hard to learn

    Crutchfield Customer Review (What's this?)

    The unit is easy to install & sounds good - after you get through the confusing manula. Kenwood di a terrible job stting upo the supprt documents on this model. The menu system is also a bit confusing - once you get the hang of it it works well. I wish it had an HD radio mdule. The redout for my sansa MP3 works great 0- but like everyone else - I ended up throwing away the very confusing Kenwood software.



    Love It!

    Ken from Naperville, IL on 2/8/2008

    Crutchfield Customer Review (What's this?)

    I have owned this model for 1 month. I bought this stereo to replcae an older KDC-X789, it's a better model but one drawback for me was the stereo face is not motarized. The X789's faceplate could tilt to 3 different positions, which is beneficial to me coz my stereo car loation is low and it help me read the faceplate. Other than the above, i love that i can connect my ipod, phone and XM to it. Bottom line i love this stereo and have been a kenwood for over 9 years. I would buy another kenwood stereo but i would have to make sure it had a motarized faceplate before purchasing it.



    Good Stereo

    Roy from St Louis,MO on 1/17/2008

    Crutchfield Customer Review (What's this?)

    Great sound. The readout is a little far back from the front and makes it difficult to read if your stereo is placed down low. Easy to setup and the usb harddrive works great. Ipod was also easy to use with the usb connection. I don't like that the remote does not shut off or turn on the Stereo.



    My Kenwood X791

    Steve from New Market, MD on 10/30/2007

    Crutchfield Customer Review (What's this?)

    Overall a good receiver with lots of features. The manual is a little weird, it has reference to other sections instead of explaining how to do something in one spot you have to go to several different sections. The other thing that is annoying, the removeable face plate is easy to remove but really HARD to reinstall. Overall I'm happy with the unit and would buy another Kenwood. I do love all the extra input devices you can use with the Kenwood



    Flawed but worth it

    Dionisio from Philly, PA on 9/27/2007

    Crutchfield Customer Review (What's this?)

    Let me start by saying I am IPOD hater (DRM infested PCB). I prefer to be able to transfer my MP3s to and from any media without worrying if the piece of electronics will play them. I give the KDC-X791 a 5 for features, 5 for sound quality, 3 for the interface and 1 for the Music Editor. DO NOT use the music editor to load music on a USB Flash drives. You are better off setting up your own folder structure and using Windows Explorer to copy your music onto the drive. I just sold my last car with the Kenwood Music Keg hard drive system in it. I was looking to upgrade the factory head unit in my new car to one with a USB interface for Flash drives and Bluetooth ready. I am a little disappointed with the change Kenwood made with the folder selection interface. The remote for my old head unit with the Music Keg allowed me to go directly from folder #5 to folder #44 by pressing "44" then folder up "+" or folder minus "- " buttons. A grand total of 3 button presses. They removed that function with the USB drive. Now I have to press the folder up "+" 39 times to get from 5 to 44. Not useful when I'm driving. The whole menu system is NOT intuitive at all. Things that are useful are buried 6 or more button presses. Again not useful while driving. I also installed the Kenwood Bluetooth Adapter with the HU. It's a huge improvement over using an ear piece (which I still use when I get out of the car). One issue I have is with the number of speed dials. Kenwood allows for 3 speed dials. Most head units have 6 radio preset buttons. I don't know why the limit it to just 3. It is a painful process of registering more than one phone. It can have 5 phones registered but only one can be active. The process of registering the first one is easy. The following phones are a pain. You also have to remember to change the default phone when you get the car. This is a little harder for my wife to do than for me. This goes back to the menu system. Overall the BT100 is a little pricey of an upgrade over headsets but the sound quality and convenience is worth it for me. I don't know what the problem was with the display mentioned in other reviews. I set it up to tell me what I want to know on one screen. While playing my MP3s it has Folder number, Track number, Track time, Title of Track, Artist, and Time of Day on one screen. I have friends with similar units from other manufactures. Kenwood is not alone with some of these flaws. The fact that X791 is still capable of inputs from SIRIUS, HD radio, and Aux (mini-jack) make it an excellent choice for future expansion. Comparing sound quality, price, and features I am happy with this purchase. I would actually give 3.5 out of 5. Crutchfield did make the whole experience an excellent one.



    Kenwood fan for 4 years now

    Crutchfield Customer Review (What's this?)

    I've been into car electronics for 4 years now and i have seen and/or installed them all somewhere along the line. Of all the brands, kenwood is the best quality. Easy to use, affordable, great features, and excellent sound quality.



    Lots of features at a good price

    Milad from Orlando, FL on 9/3/2007

    Crutchfield Customer Review (What's this?)

    When I began to look for a new deck I first considered Alpine as they have an excellent rep and great sound quality, but are costly and don't have many features in any given price range when compared to other brands. I ran into this head unit at a local audio shop and compared the sound quality to other brands, This unit is amazing. The sound quality is first rate and the amount of features you get for the price is great. This unit allow fine tuning of the audio in many respects and makes it easy. The display is large and easy to read although the screen savers are quite cheesy, but I purchased it for sound quality not the display. This unit also has a usb port that was placed in my glove box. I never again have to change a cd as I have all my favorite songs on one device. FYI, you can make different folder for your music but when accessing them thru the head unit it does not show the name of the folders, but rather show folder 1,2,3....<BR><BR>In all this is a great deck with impressive sound quality and features. Tahnk you crutchfield, They have the best support and thats why I pay a few bucks more. You get what you pay for.



    iPod/BlueTooth Interface Needs Work

    Stash from Chandler, AZ on 8/18/2007

    2000 Jeep Wrangler
    Crutchfield Customer Review (What's this?)

    Never owned a Kenwood before, and I was looking to upgrade my deck to a iPod-ready, BlueTooth-ready in-dash receiver. So this is the unit I chose.<BR><BR>Needless to say, I was a bit disappointed in the iPod interface. First, when the unit turns on, it takes quite a bit of time for the unit to communicate with the iPod before you hear any music. Sometimes 30 seconds up to a minute. Second, Kenwood provides a means of browsing through artists and selecting songs from a particular artist. Artists are arranged alphabetically and the scrolling capability from A-Z is way too slow... I find myself cranking away on the knob just to locate a song by &quot;ZZ Top&quot;. Third, I was under the impression before I bought the unit that I would have access to my playlists from the receiver unit. Not the case. Fourth, I still have not found out how to re-sync the song catalog on the unit with my iPod. For example, if I add a new song to my iPod, it's not available in the song catalog on the kdc-x791.<BR><BR>Also, perhaps the BlueTooth kit may work better on other phones, but with my RIM Blackberry the $200 BlueTooth kit is worthless. It pairs with the phone just fine, but disconnects after 20 or 30 seconds or so. Then re-connects again. It keeps connecting, disconnecting, and re-connecting over and over. I even tested it by placing my phone right next the BlueTooth receiver unit. Same behavior.<BR><BR>Otherwise, if not interested in the iPod or BlueTooth interfaces, it's not a bad unit. If interested in iPod and BlueTooth capability, there are other solutions out there to try.<BR>



    Worth Every Dollar!!

    TJ from Alamogordo, NM on 8/5/2007

    If you want variety with sound and equalizing settings this is the unit to do it. I am personally a JVC fan but someone talked me into walking in he the Kenwood lifestyle and I am pleased and couldn't ask for anything better. This pushes everything in my car with no problem. The settings lets you control every bit of your sound. I would agree with on the reviews and say that the manual doesn't really explain all the features. If you are anyone is really considering buying a new head unit and like to control all the features of sound this unit is it. As far as graphics they are great, but just controlling what how and what you hear, that is the greatest.

    Crutchfield Customer Review (What's this?)

    Everyone seems to like this receiver, but I hated it. I bought it, installed it, and returned it.<BR><BR>First of all, its display is horrible. The face sticks out of the dashboard way too far, and the display is too small and hard to read in comparison to the whole face. The graphics are pretty much pink and blue, and if you're older than 6 and aren't entertained by dancing dolphins and a mixed off-road/hunting scene displayed in pastels that are hard to see, you won't like this receiver.<BR><BR>The knobs are hard to use. They're made of a strange, slippery rubber and they're small. If you accidentally press in on the volume knob (easy mistake to make), you're taken to a menu system that's hard to exit, and when you're USING that menu system you can't turn the volume if you accidentally reach too fast for the vol - when you NEED the volume to go down - you may shoot yourself in the foot.<BR><BR>The sound is fine, but hard to adjust. The controls to adjust it aren't intuitive. It's clean up to high volume, but NOT as clean as the JVC BT1 I got with Bluetooth. (BUY THE JVC! You'll love it!)<BR><BR>Honestly, the display is so bad on this thing - I would rather give up listening to radio than be stuck with it for life. It is a really, really, really poor receiver.<BR><BR>The face doesn't clip on well. It can easily be moved even when attached so it ends up hanging at a funny angle.<BR><BR>This receiver is PERFECT for a 1987 S-10/first car for a young woman who likes pink and blue dolphins.<BR><BR>



    KDC-X791 A great receiver

    Crutchfield Customer Review (What's this?)

    I was sort of stuck with getting another Kenwood receiver if I still wanted to use my Kenwood CD changer. I also needed the Aux for my portable Sirius radio. After reading the extensive info Crutchfield has on equipment, I decided to purchase. I am happy I did. Plenty of &quot;bells and whistles&quot; for anyone that wants many options. Changing the layout of the display is great. It lets you set it up just the way you want it to look. Color changes add to this feature.<BR> Sound is very good with OEM speakers in my van. The removeable face plate comes off with out any problem, getting it back on takes some work. You must line up a small pin in a hole on the left side first and the same on the right side. It may become simple with time, but something that is difficult in low light conditions.<BR> The manual could be improved towards better explaining what they mean. I feel it was written by an expert with the unit. Getting it out of the demo mode took extensive reading and tech support to turn it off. That info was taped to my old unit this one replaced.<BR> Still having problems with the usb and getting it to read the files created with the included music program. I am sure that problem will be solved soon.<BR> I would have to take a few fractions of points off due to the problems listed, but am pleased with the purchase. I am also always pleased in the speed that crutchfield gets a product shipped fast. I would advise anyone that likes what they read about this unit to make a purchase. You also will like what you receive.



    Great Stereo

    Joseph from Weaver, AL on 4/25/2007

    I'm not really a Kenwood fan. I've had not so nice experiences with the brand. But, I took a leap into the great unknown and took a chance. Man, am I impressed! I still haven't learned all that I can with this stereo. I would strongly suggest a try on this unit. I've gone to the darkside! I am a reformed man. So many bells and whistles! Well worth the money.



    Great Sound on Factory Speakers

    Andrew from Sheridan, IN on 3/8/2007

    2006 Pontiac Grand Prix

    I was very anxious to get my hands on this new head unit. I have never owned a Kenwood before. I was looking for something for my 06' Grand Prix that could handle an iPod natively and could do HD radio (albeit with add-on module). I also needed steering wheel controls (also an extra module) so my choice was split between an Alpine CDA-9857 and this. I ended up with this when Crutchfield said the Alpine didn't fit my dash. I hadn&#8217;t owned either brand before so it wasn&#8217;t that big of deal.<BR><BR>The sound quality on this guy is pretty amazing compared to the factory HU. With a flat EQ, I can hear everything in the song with a rich overall tone. I don&#8217;t feel I have to &#8220;crank&#8221; up the volume to get more from this HU.<BR><BR>The interface is pretty good although I can't compare it to anything really. It does require the manual to understand most settings in depth. It has a pretty fast response time in the menus except with changing sources. Using the USB source with MP3's is very cool and switching between song files is as fast as the CD.<BR><BR>I have future plans to add a 10' sub w/ amp. I can only imagine what it will sound like after such an improvement already.<BR><BR>I give this 4.8 stars. -0.1 for taking up AUX and USB for iPod control and -0.1 for some convolution in the menus.<BR>
