Our take on the Kenwood Excelon KDC-X303

Bluetooth® is a thing these days! And the Kenwood Excelon KDC-X303 CD receiver provides two big direct-access buttons that let you wirelessly stream music and make hands-free calls quickly and easily. Kenwood also added a variable-color display, Internet radio controls, and a USB port for high-res music playback. And because it's part of the Excelon family, you'll have deep tone controls, plenty of options for system expansion, and a 2-year warranty.

Simplicity paired with Excelon quality

Bluetooth® is a thing these days! And the Kenwood Excelon KDC-X303 CD receiver provides two big direct-access buttons that let you wirelessly stream music and make hands-free calls quickly and easily. Kenwood also added a variable-color display, Internet radio controls, and a USB port for high-res music playback. And because it's part of the Excelon family, you'll have deep tone controls, plenty of options for system expansion, and a 2-year warranty.

The goodness that is Bluetooth

In addition to wireless access to music and calls, the KDC-X303 enables you to pair two Bluetooth-equipped phones and quickly switch between them for hands-free calling. And when you're streaming audio, the Music Mix feature lets you pair five phones so everybody in the car can take turns picking the tunes. You can also control this stereo directly from your iPhone® or Android™ phone using Kenwood's free Remote app, which comes in handy if your stereo is hidden away or in a custom location. It's okay to think outside the box.

The sources you want

With controls for Spotify®, iHeartRadio®, Pandora®, SiriusXM (optional tuner and subscription required), this Kenwood is ready for radio. Its front-panel USB port also lets you plug in and play music from your iPhone® or Android™, or you can play your own digital music stored on a USB drive including high-res FLAC files (up to 24-bit/96kHz). And if that isn't enough music for you, you can also satisfy your music fix using the receiver's front aux input for a portable music player.

Tweak and add to your system

With its three sets of 5-volt preamp outputs, the KDC-X303 delivers a super-clean signal to amplifiers in your setup. Combine those with the built-in 13-band equalizer and digital time alignment, and you've got a serious audio hub for an ever-growing sound system. And just to make sure you have the right look in your vehicle, you get to pick the color for the receiver's 1.5-line display and control buttons.

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.

    Very happy with this radio. Sound quality is excellent. All the features you will ever need and more. The extra money spent having Crutchfield assemble a wiring harness for my vehicle was well worth it. Made installation very easy.

    Very happy with this radio. Sound quality is excellent. All the features you will ever need and more. The extra money spent having Crutchfield assemble a wiring harness for my vehicle was well worth it. Made installation very easy.

    Pros: Everything you will ever need in a car stereo.

    Cons: The location of the volume/function knob. When turning the volume knob to cycle through functions, your hand easily blocks the view of the screen. A better placement or means to access functions would be better.

    Good stereo, easy install especially with Crutchfield's Ready Harness service (see other review). As a few others mention, the functions to change settings is a little complicated and the buttons are close together. Overall this product is great and would recommend!

    francis from Issaquah, WA on 3/8/2019

    sounds great, I love the USB so I can plug in my music library. My one complaint is that I want the clock as the default screen. I don't care if it switches to indicate the track it's playing when a new song begins, but the default screen with the clock is giant a GIANT "DATE MM/YY and the current DAY (MTWTFSS). The clock indicating the time is a teeny tiny sliver of space under the date, that I can barely see. It's not like I am driving around wondering what date it is, or what day of the week it happens to be,.... But being able to glance down and see the CURRENT TIME easily is more useful than the day or date.

    Pros: almost perfect...

    Cons: clock display is teeny tiny

    Crutchfield Customer Review (What's this?)

    Great unit, especially for the price. Good clean sounding and plenty of parameters to tweak the sound anyway you like it. My one caveat is that the controls/settings are FAR from intuitive or simple, and the buttons are way too small for my fingers. For that reason I'd actually give it a four-and-a-half star rating if permitted. But once you get it set up it's a solid unit, and the higher-than-most voltage outputs are great to push my amps efficiently.

    Crutchfield Customer Review (What's this?)

    I've always had a great experience w kenwood excelon recievers. I recently installed the KDC-X303 in my 07 dodge 1500. I have the premium sound package ( infinity speakers) but I didn't have blue tooth or hands free calling. This receiver offers both that work flawlessly and brought more power and clarity to the factory speakers. The installation was a piece of cake thanks to crutchfields installation hardware suggestions and also the instructions were spot on

    Pros: Blue tooth hands free calling work well and are easy to operate. The face panel color options are great and easy to match to the rest of the dash lights of the vehicle

    Cons: None

    Fast/easy installation

    Great stereo with amazing features. Installed in a Mustang in less than two hours. Program cell phone was quick and easy. Even programmed background colors to match my gauges.

    Pros: Features

    Cons: A little challenging to program at first.

    Crutchfield Customer Review (What's this?)

    This receiver sounds great. The number of source input options is also a big plus for us. We are very pleased with it, but I do have two complaints. First, I can't just tap on the source button in rapid fire sequence to get to the input I want; I have to tap the source button, wait a second or so for that source to activate, and then tap again to toggle to the input I'm looking for. It works, just kind of annoying. Secondly, there are a lot of menu screens to go through to get to certain features. For example, we often use the fader to put kids CD's on the rear speakers only. It takes a few menu inputs to make that change. With so many options to work with, I don't know how you improve this...but we are used to having fade and balance controls right on the face of the factory radio. So for us, it was going backward. But again, not something that takes away from the the overall satisfaction of the radio. This is our first radio with Bluetooth and it works perfectly. We have cheap smartphones, so weren't necessarily expecting the BT protocols to be compatible, but our phones paired up right out of the box. Very happy about that. The installation was very easy and the included instructions and suggested accessories were spot on for the install.

    Excellent customer service and support for installation. Would recommend this store if you are thinking of getting an aftermarket radio.

    Pros: Product was an exact fit with the addition of purchasing the optional car specific harness it made the install very easy. The unit has great sound and lighting options. Would recommend.

    Cons: None

    Great sounding

    Crutchfield Customer Review (What's this?)

    So far I really love this head unit. I was worried at first but it's much more than I expected.

    Pros: This is a big improvement over my factory radio and it has a lot of great features

    Cons: Can be a bit dim in direct sunlight but that's expected with these types of displays

    Sounds Great but too complicated.

    Crutchfield customer from Riverside, CA on 2/11/2019

    Crutchfield Customer Review (What's this?)

    The unit sounds great, but functions are too complicated. Also, some buttons are small and near each other with the possibility to press the wrong one.

    Pros: Sounds amazing with a lot of power.

    Cons: Functions too complicated. Some buttons near each other that its possible to press wrong one.

    Great Sound

    Cons: None

    Excellent Features, Sound, & Look

    Scott from Moseley, VA on 1/30/2019

    2003 Honda S2000
    Crutchfield Customer Review (What's this?)

    Excellent sound and features. I put this in my S2000 to be able to listen to Pandora, iHeartRadio, etc. and, more importantly, have hands free phone calls. Being able to still control the unit with the S2k radio controls was a personal requirement so I bought the Steering Wheel Control Adapter as well.

    Pros: Features, look, ease of installation, price.


    Good receiver for the money!

    Crutchfield customer from Suwanee, GA on 1/28/2019

    1999 BMW M3
    Crutchfield Customer Review (What's this?)

    It's a pretty descent receiver. There could be more options for color illumination, I couldn't quite get it to match 100% for my factory lighting, but it's 'close enough'. The menu structure is a little tricky and the color illumination goes into cycling all the colors of the rainbow when you start changing things. The Kenwood App is kind of useless to me, it doesn't really allow you to configure the receiver unlike others I've seen. The sound quality is very good and the overall look of the display is nice and clean fitting with most older 90's simple interiors. Blue Tooth connectivity is pretty reliable and works well and sounds good.

    Pros: Sounds good. Looks clean. Easy to install. Blue Tooth works good. Price.

    Cons: Color illumination isn't 100% match to amber/red interior but pretty close. Menu navigation is kind of weird.

    Good stereo for the price

    2002 Jeep Grand Cherokee
    Crutchfield Customer Review (What's this?)

    Great stereo! Great speakers! Easy install! Great experience! This replaced the factory stereo/speakers on a 2002 Jeep Grand Cherokee. The sound is incredible compared to the factory setup. It could use a little more bass, but I may add a sub down the road. I did purchase the foam speaker baffles, but they didn't fit right. I had to cut 2 to 3 inches off the top to get them to fit. They are way too deep and bind up on the windows. I was told that the factory Infinity amp would be OK to run the system through. This turns out to be incorrect info as the amp's crossover restricts most frequencies from getting to the speakers. Tech support provided guidance to bypass the amp and resolved the issue. It now sounds great, just don't use the factory amp.

    This is a great stereo unit and with the fantastic pre- wire connections service that Crutchfield offers for a very small fee, I who really never installed a system in car along witha call to very helpful and friendly tech support department at Crutchfield was able to easily install this system in my Honda S2000 and it looks like a professional installed it and I saved about 350.00 dollars on install . I would very much recommend Crutchfield to anyone in the market to replace auto stereo equipment...

    Installation was not difficult after a couple of calls to tech support for clarification. The unit itself performs as advertised, good sound, many functionalities. My only complaint is that operation of the many functions are not intuitive and the tuning buttons are too small for fat, old fingers. Good value for the price. Excellent service from Crutchfield!




    Catherine from Rockingham, VA on 11/30/2018

    So far so Great. I purchase this a month ago to replace another old well used Kenwood in my really old CRV. Fits perfectly, easy to see/use controls, love the display of what's playing, color choices on display, great radio tuning/search features and sound controls, easy access CD player, love that the USB slot is covered so it doesn't collect dust, everything sounds and works great so far. What's not to like. Will be trying Bluetooth on my next trip but expect good results. Love Crutchfield - they explained everything to help me decide on the right unit for me and did a good job on installation.Thanks!

    Optional IR Remote: The KDC-X303 is compatible with Kenwood's IR remote control (RC-406, sold separately) for wireless operation of the receiver.

    Display Features

    Detachable Face: The Kenwood KDC-X303 features a single front loading CD face that detaches from the chassis to deter theft. There is no protective face case included. 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.

    1.5 Line Display: The KDC-X303 is equipped with a 13-digit, 1.5-line LCD screen which allows you to view source information along with the clock (the time will be in a smaller text). You can select between English or Spanish text.

    Variable Color Illumination: The Kenwood Excelon KDC-X303 features variable color display and button illumination. You can choose from one of 24 preset colors, have the unit scan through all 24 preset colors continuously, or customize your own color (RGB; 0-9). The custom setting allows you to individually adjust the intensity of Red, Green, and Blue (from 0-9) to better match your vehicle's interior lights. The same color setting is applied to both the display and buttons, or you can choose a different color for Zone 1 and Zone 2 (see owner's manual illustration). The Kenwood logo remains red.

    Text Scroll: The KDC-X303 will display song/artist information text from CD, USB, Bluetooth, iPod, and Android. You can set the text scrolling feature to three different modes (Auto, Once, or Off) to scroll longer titles across the screen.

    Brightness & Dimmer: You can adjust the brightness of the LCD and button illumination independently or together (from 0-31). You can also dim (on or off) the display and button illumination. You can even set a specific time for the "Off" and "On" dimmer setting to be activated.

    12Hr/24Hr Clock: The head unit can be set to display a 12hr or 24hr clock. The unit also displays the day (Sun, Mon, Tue, Wed, Thu, Fri, or Sat). The day and time can be displayed by itself, or the time (not day) can be displayed along with source information. The day & time can be selected to remain on, even if the head unit is switched off (as long as the vehicle's key is in the "accessory" or "on" position).

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

    Crutchfield asked  
    Why did you buy this?

    It's a kenwood. Need I say more.?..... [ Sara  Mar 13, 2019 ]
    Features, price, reliability, BlueTooth, Customer Ratings. [ James  Feb 21, 2019 ]
    Very good price [ Jeffrey  Feb 15, 2019 ]
    I have been installing Kenwood receivers in my vehicles for many years. I've put them in My cars, jeeps, trucks, boat and Harley. The units I have installed in the many jeeps I have owned over the years have held up in some of the harshest conditions including mud and water. That being said. This unit is going in my wife's car that hopefully won't see any mud or water. In my opinion you cannot get a better receiver with all the features for the money. "Kenwood Rocks" [ JAMES  Feb 14, 2019 ]
    m a friend has this model and I liked the features and it has great reviews. [ timothy  Feb 14, 2019 ]
    previous customer reviews, full feature and 2yr warranty [ Don  Feb 13, 2019 ]
    I like the quality of Kenwood radios. I have them in all my vehicles [ John  Feb 12, 2019 ]
    All the features [ Andy  Feb 12, 2019 ]
    excellent product for the price [ Darryl  Feb 12, 2019 ]
    My brother just got an old Honda for his birthday and the Kenwood Excelon looks like a reasonably priced upgrade to his factory radio. [ Bronson  Feb 10, 2019 ]
    Kenwood has excellent sound quality [ Carl  Feb 08, 2019 ]
    The features of this unit fit my needs.The old style volume knob was the selling point for me plus the Kenwood name, removable face and features of the unit. it even comes with a 2 year unconditional warranty? Marisa really listened to my wants and feature request. Unbeatable anywhere. [ Gary  Feb 02, 2019 ]
    Good reviews like the look of it and features,and a step up from the KDC-BT350U I saw at Walmart. [ David  Dec 17, 2018 ]
    Hard decision.--Just wanted a basic radio. Both the Alpine CDE-170 and Kenwood KDC-X303 met this need. Bottom line the Kenwood offered more bang for the buck. [ Craig  Nov 27, 2018 ]
    I chose this Kenwood CD receiver for my teenage daughter, because the factory system in her 2001 Infiniti QX4 did not provide any way for her to play music from her iPhone or answer phone calls hands-free. I really liked the layout and easy access of the buttons for answering calls and choosing the music source. This receiver has Bluetooth connectivity for both phone calls and wireless music streaming, plus offers front USB and AUX inputs. I think this will be a great replacement stereo. [ STEFAN  Nov 26, 2018 ]
    Quality and simple. [ Kevin  Nov 23, 2018 ]
    Had everything I needed [ David  Nov 23, 2018 ]

    Seemed like an excellent thing to do at the time! [ Maikai  Nov 15, 2018 ]

    Meets our needs [ Jiggs  Nov 08, 2018 ]
    A quality brand, with the most quality performance for the dollar, what more could one ask for! [ Jason  Nov 07, 2018 ]
    Pricier than competing products with similar features, but came recommended by an audio-phile friend as having good power output. [ Dave  Oct 30, 2018 ]
    For years, I've always been a fan of the Excelon series Kenwood units. When it was time for a head unit in a vehicle of mine, it went straight to the Excelon series and chose the best one for my use of this vehicle. Thank you Kenwood! [ Erik  Oct 23, 2018 ]
    I've had a Ken wood stereo in the past and really liked it and I did my reasearch and this stereo is the best bang for your buck [ Mason  Oct 15, 2018 ]

    There is a PDF file of the owner's manual on Kenwood's website. I cannot include a link to it in my response, but searching "Kenwood Excelon KDC-X303 Manual" works [ Taylor  Feb 03, 2019 ]
    None of that helped me ultimately what worked was crutchfields tech guys [ Laura  Feb 02, 2019 ]

    Yes i download from apple store in my cell and is very easy to use. at first one you can practice about 20 minute but most later you can convert an expert. [ luis  Jan 29, 2019 ]

    As long as you have and android or iPhone smartphone you can download the app to your device and control your reciever. Search for a link for Kenwood apps and it pulls up their site. I can't paste it here because its not allowed in responses. [ John  Jan 29, 2019 ]
    Yes I have it downloaded on my iPhone [ Ethan  Jan 29, 2019 ]
    Download the remote app on your phone to use via Bluetooth. Have not tried other Kenwood remotes with this headunit to see if they work. [ Greyson  Nov 13, 2018 ]
    You have to install the app in the App Store [ Scott  Nov 13, 2018 ]
    I think u have to purchase seperate. Mine did not come with one [ Billy  Nov 13, 2018 ]
    I was wondering the same thing. The manual talks a lot about it, and doesn't suggest that it's optional. But no remote was in the box. There is, however, an app on the iOS App Store, so perhaps that's what they're referring to. Haven't tried it yet. [ Dave  Nov 12, 2018 ]
    Press the src button until it reads standby. [ Chris  Oct 22, 2018 ]
    hold the src button for three to four seconds [ Barrick  Oct 22, 2018 ]
    It is the source button. Push it until it goes to standby. Or hold it down to turn off power. [ Jason Lee  Oct 22, 2018 ]
    Press and hold the source button for 3 seconds or till it says standby. Middle button ,far left side. [ John  Oct 22, 2018 ]
