In-Dash Receiver Specifications

Receiver Size

Single DIN: 1 DIN dimensions will work with all single DIN installation kits we have to offer. Single DIN radios are the most common size for after-market stereos.

Single DIN slot with flip-out screen: The DIN stereo includes a retractable, flip-out screen. Before purchasing, make measurements to be sure there is no interference with dash accessories such as A/C vents or shift levers.

Single DIN slot with a larger face: Standard single DIN size, but the display is larger then the standard single DIN size. Due to the nature of the larger face, problems may arise when installing in particular vehicles. These stereos are great for single DIN slots where you want a larger screen.

1.5 DIN: This size is very uncommon in vehicles, however this size opening is most commonly found in Chrysler and Chevrolet vehicles.

Double DIN: Approximately 4-inches in height, this size is becoming more common every year. Prior to 2000, this size was typically only found in Japanese vehicles such as those made by Honda or Toyota. Now, it is becoming more popular for many vehicles to be fit with a Double DIN opening.

Single DIN
Faceplate Security

Detachable / Removable faceplate security: The most common anti-theft feature. It allows you to take the faceplate with you, thus disallowing operation, which deters theft.

Security Codes: Mainly a feature in high end video units which do not have a detachable face / screen. Once the unit is uninstalled (or stolen), a security code (or PIN) is required upon reinstallation. Though you no longer have your unit after the theft, the thief also does not have your security code, which makes the unit useless. The hope is the thief knows which units have security codes and he/she chooses not to steal your unit because of the security code.

Ghost technology: This is not commonly used, but can be found primarily in a select number of 2004-2005 head units. It creates an illusion that no unit is installed by appearing completely black when turned off. Potential thieves may steer clear because it appears as though no head unit is installed.

Anti-theft covers: Similar to ghost and hiding faces because they only create an illusion that the face/unit is not in place.

ESN: Stands for Electronic Serial Number. Allows the disabling of the radio and allows tracking if it is stolen.

Motorized Faceplate
Some in-dash car stereos feature a motorized faceplate that moves to expose a CD or DVD slot. This is a convenient feature that allows the front display to be larger and easier to read. The positioning of the monitor gives you control over the angle you would like to view information on the stereo.
Remote Control
Allows control of specific features and functions from a remote control. Typically they are used to prevent button wear on your radio, or to allow easier navigation of menus.
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison.

50 watts x 4 channels
RMS Power Output
The amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS rating, the louder and cleaner your music sounds. The RMS output figure is much more accurate than the peak rating when comparing products.
22 watts x 4 channels
Preamp RCA Outputs
RCA outputs, commonly known as preamp outputs, allow you to connect one or sometimes multiple external amplifiers. An in-dash receiver will commonly have one, two or three sets of RCA outputs that can be used to connect external amplifiers and other components. One pair of RCA outputs will typically provide a full range signal that can be used for most subwoofer or speaker amplifiers. Two pairs of RCA outputs can typically be configured as four full range signals, or also as two full range and two subwoofer signals. Three sets of RCA outputs will almost always produce four speaker signals and two subwoofer signals for use with multiple amplifiers.
3 Pairs (Front, Rear, and Subwoofer)
Dedicated Subwoofer Preamp RCA Output
A dedicated output that has a built-in low-pass crossover for specific connection to a subwoofer amplifier that powers a low frequency driver, typically a subwoofer.
Preamp Voltage
The preamp output rating is measured in volts (V). The higher the rating, the stronger the signal. This results in less unwanted noise being picked up.
4 volts
Built-In Equalizer
The number of graphic or parametric equalizer bands the stereo receiver is equipped with. The more EQ options, the more you will be able to adjust your music to your liking.
Display Type
The type of display on your receiver refers to the monitor that is used to display the source information such as song names, radio stations, or track times.

Dot-Matrix Text Display: A simple display which uses dots in specific illuminated color(s) to light up and form letters or numbers that are displayed on the receiver.

Graphic or Motion Display: Typically found in mid to high-end receivers and give your text information and receiver more life by adding motion, backgrounds, or multiple colors to your display. There are types of graphic displays such as 3D Graphic, Motion, and OEL (Organic Electroluminescent) displays. They can range from one color to full color displays and typically allow you to select from one of many built-in animations, background images, screensavers or other graphics to enhance your experience and add an extra bit of personality to your system. Some units also come with software that allow you to load your own customizable pictures or animations.

LCD Monitor Display: Can be as small as 2" or as large as 10". Some LCD displays are motorized for angle adjustment. LCD monitors display full motion video playback as well as your standard text such as track status, radio station information and more depending on the receiver's features.

LCD Text Display
Display Color
The display color refers to the color of the text and or graphics on the receiver.

Multi-Color: When more than one color is on the display, for example one part of the text is white, while the other part is blue.

Variable-Color: The display colors can be changed by the user. If the default color of text/display is blue for example, the user can change the settings to where the color turns to red. Variable color displays are typically described in detail in the item's description.

TFT-LCD Display: In-dash receivers with a video screen that display multiple colors and often times video such as DVD, navigation or other video sources.

Variable Colors
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.


Playback Features

AM/FM Tuner
Most in-dash CD players have AM/FM playback allowing you listen to your favorite local radio stations.
FM Presets
The number of FM radio stations that can be stored as presets.
AM Presets
The number of AM radio stations that can be stored as presets.
CD-R/RW Playback
This feature refers to whether or not the CD player will play finalized CD-R discs and/or CD-RW discs.
MP3 Playback
This feature refers to whether or not the CD player will play discs encoded with MP3 files. To burn a MP3 encoded disc, use the "data" mode on your CD Recorder and finalize the session and/or CD.
WMA Playback
This feature refers to whether or not the CD player will play discs encoded with WMA files. To burn a WMA encoded disc, use the "data" mode on your CD Recorder and finalize the session and/or CD.
DVD / Video Playback
This feature refers to whether or not the receiver will play DVD (or other listed) video disc formats. Unless otherwise noted, the unit is not guaranteed to play recorded DVDs.
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

Audio / Video Inputs

USB Input
This feature refers to whether or not the receiver features an input to connect a USB device via standard USB or mini-USB. The USB input may be a connection on the front or rear of the unit with an extension cable for connecting devices to the receiver. Some units have an optional input that allows for a USB adapter to be purchased separately and used with the unit.
Number of Front USB Inputs
Additional Audio/Video Inputs
These inputs enable the unit to receive an audio or video signal from a separate source. There are many different types of connections and ways to accomplish this. Most common are RCA Composite cables and 3.5mm mini-jack plugs.

RCA Composite Inputs
These are your typical red, white, and yellow RCA composite cables that are common among devices with audio and video inputs. The red and white cables are dedicated for audio. The red cable is for the right channel and the white is for the left channel. The yellow cable is specifically for the video signal. Because this type of auxiliary cable contains 2 channels of audio, it will support stereo sound.

This is commonly referred to as a mini-jack or a headphone jack. It is a 3.5mm plug that transfers audio only. There is a right and left audio channel on the plug which allows for stereo sound playback.

3.5mm AV Input
These plugs look similar to the common 3.5mm mini-jack, however they carry a third channel dedicated for video.

This means that an auxiliary input is possible, but only with the use of an optional accessory. These optional adapters will sometimes use the CD Changer port or other port on the back of a unit that might restrict the use of other expandability features. These accessories are typically sold separately.

Front 3.5mm Audio Input

Expandability Features

Built-in navigation is a convenient feature that allows the driver to receive driving directions and guidance.

Some in-dash head units are built-in with the navigation features, while others require an add on navigation box. Other navigation options include portable navigation units that you can take with you or attach to the dash of your vehicle.

So far so good

March 4, 2015

I have had this unit in for a couple of weeks.
Pros: It has all of the features I wanted that would fit my truck (really wanted DD but didn't want to go through the extra expense of modding the truck and didn;t want a flip screen). The unit sounds nice, has a clean look and is easily controlled once you get used to all of the sub menus.

Cons: Most of the colors that can be chosen you cannot see in direct sunlight. The aqua color works best for me for sunlight visibility. The volume knob is tight but its brand new and is already loosing up, It is slick as well so if you plan on using the headunit instead of the remote, be warned the volume knob will be difficult to operate until it is "broken in".

I haven't gotten my subs in yet so I cannot speak about the 4v preout yet. I will update this review sometime down the road.

This is one of the nicest Kenwoods I have owned. I have two others an really dislike the radio selection method. I am glad they went back to the preset buttons. This makes it much easier to change channels when driving without having to look at the radio.

I just installed my X599 2 weeks ago along with pioneer A series speakers and an audio pipe subwoofer. Let me tell you the hpf, lpf, and phase control make it a breeze to set up the sound stage in the car. The multicolor display is nice, but as some have said it is quite dim during the day. 4v preamp outputs let me amp strain less and still put out lots of bass. All in all I would buy this head unit over and over again because of the price and features.

Awesome Head Unit

June 29, 2016

Upgraded from a KDC-396 i believe. That head unit was pretty good, but the Bluetooth connectivity would not play any bass, all the low frequencies were gone. I got around this by using an aux cord. I also felt like there was some sound quality missing.

Onto the XDC-599. Wow...What a difference. The bluetooth works flawlessly now. But the range of customizability, setting speaker size, 15 band equalizer, setting frequency ranges for tweeter and woofers...I was impressed. Finally am able to get out of my system what I paid into it. Completely worth it.

Nice look, great price for the features

February 22, 2016

After much deliberation I decided on this head unit for my Tahoe, which had a 1.5 DIN configuration. I wanted to connect to a 4 channel amp and needed the appropriate outputs. I compared side by side with Alpine and Sony offerings and this just had everything at a better price. I know Kenwood makes quality products (amp and speakers are also kenwood).

great radio.I love everything about this radio
greg l on Jun 4, 2016
Had all of the features I wanted. Was a close call against a Pioneer that was almost exactly the same, but the 4v preamp sealed the deal for only an extra ten bucks.

Does this head unit come with EVERYTHING needed for the install including the dash kit, harness that plugs into the unit, and aftermarket harness to connect into the factory plugs?
Trevor M on Nov 16, 2015
Best Answer: If you get the free kit they offer through sonic for your specific vehicle, yes it does. Well mine was free at the time. I only used the mounting kit in my truck however, since a prvious owner had hacked up the wiring under the dash for the factory radio.

Will this head unit work with the factory xm tuner?
Heather G on Jan 11, 2016
Best Answer: Hi Heather,

Technically speaking, there is NO headunit that connects directly to an OEM Satellite feature. That feature is the responsibility of the HARNESS. Of which, our system is not designed to offer, because it is a rather rare piece and often there is no compatible harness for a given vehicle. To get straight to the point, give our sales team a call to help you find an answer (i.e. an answer to whether or not a harness exists for your vehicle). From there, the headunit must have an available auxiliary input; preferably on the rear of the stereo and preferably an RCA connection.

To be transparent, said harness if often rather expensive, which means the aftermarket V300 tuner is typically the 'smarter buy' .

I have a 1999 Mazda Miata with a factory Bose system. I'd like to replace the head unit, but keep the factory speakers and amp. Will the free harness that comes with the Kenwood KDC-X599 support the existing amp?
Donald W on Aug 29, 2015
Best Answer: Hello Donald,

If wired properly, it will support both the speakers and amplifier. However, SOME headunits (unfortunately it cannot be determined which of the hundreds) will provide a bit too much "juice/power" to the amplifier, because of the high level outputs. So remedy this, we often recommend the Scosche OEA-4, to adjust the levels going to the amplifier. Give our sales team a call, to try to work the part into the price of the headunit; no promises, but they'll certainly try =]!
