I bought this for the preamp voltage.. but I was very pleased when I purchased this. ... it looks great and I look all of the options that comes with this head unit. It takes a little getting use to if you aren't accustom to Kenwood products... I would definitely recommend it...

In-Dash Receiver Specifications
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.
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.
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.
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.
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.
- RMS Power
- Signal-to-Noise Ratio
This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.
Audio / Video Inputs
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.
Monitor Screen Features
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.
If "Yes", then the aftermarket stereo is compatible with steering wheel remote controls. If an additional accessory is required for the steering wheel controls to work properly, a compatible piece will be listed.

I bought this Head Unit to replace a entry level Sony Xplod, and what an upgrade it was. I really have started to get into car audio hardcore and I wanted a really nice head unit to go along with all of my nice aftermarket products. I currently have all Rockford Fosgate Punch speakers and Fosgate Power amps along with all Fosgate wiring. The thing I love about the Excelon line is that they all have 4 volt pre-outs. It just makes for a cleaner signal to me.This x998 makes my speakers and sub sound so clean and makes them get super loud if I want. The features this radio have make it worth the money to me. I love that I can choose the speaker size and sub woofer size. The custom 13 band EQ is awesome. If you are not familiar with advanced settings this radio can be a bit overwhelming. I however am pretty tech savvy so it was easy for me to pick up on everything. There is an awesome review on how to use this radio on YouTube for those who have trouble. The Pros are its a top of the line radio. The look is sharp and clean. The Bluetooth sounds awesome on my Galaxy S3, the phone calling and receiving option works good, the CD and USB have a dust cover, the 4v pre-outs, and it just produces a nice clean sound. Also I love the sound elevation feature( I'm 6'3 so its nice to make the sound come from up high in my truck, really nice feature) The only con for me is its kind of hard to read the screen during the bright daylight (But i don't mind that, the Pros far outweigh this con) Overall its a great upgrade for me and it makes a huge difference in sound quality. Definitely worth the money. Sonic is the best place to buy from!!! I highly recommend this radio!!!!!

My radio has locked up a couple times since I've had it. You have to change the presets for every source. instead of making things simple and having to change the preset one time, you have to change it for every source which is annoying. It is especially annoying if you have to do this over and over again because of it freezing up and you having to reset the radio to make it work, or if something happens to your battery and it gets reset anyway. I can't go between auto 1, 2, or manual with the remote. If your operating this radio with the remote and you left it on preset mode, you can't get out of it with the remote, which means you have to physically press the button on the radio. In other words, backseat listeners are out of luck! The display is too hard to read. You're screwed if it's sunny out, which is almost always.

The Kenwood KDC-X998 does what I want: (1) play CD's, (2) stream Rhapsody via Bluetooth from my iPhone 6 and iPad and (3) has HD Radio. No complaints here.
You can program up to 18 presets on one band and combine whatever you want AM/FM/analog/HD. No changing from band to band to band after you get past 6 presets like on most head units.
I tried a Pioneer DEH-X9600BHS but it had Bluetooth issues. I then tried a Sony MEX-GS810BH but it had issues with the radio [both analog and HD].
The Kenwood just works. It also has some DSP options that some folks may be able to leverage. At the very least , users should use the time alignment feature.
It is currently paired with a Helix DSP 8-channel digital signal processing unit, JL Audio XD700/5 power amplifier, JL Audio 10TW3-D4 subwoofer and the front OEM drivers in a mid-sized SUV. The front OEM drivers consist of 6x9's in the doors, 2-1/2's in the dash corners and tweeters in the pillars. I am still dialing in the Helix DSP and will most likely install aftermarket component drivers, but the Helix DSP really helps the OEM drivers sound better.
I would certainly recommend this head unit.

I have had five Kenwood receivers. One is a double din. I have never been so delighted to use a stereo as I am with this model. It is simply easy to use. I usually use Aux, HD Radio, and BT Audio. I don't use more, but switching between could not be easier.
The looks are sweet too. It has a highly refined look to it. I make it show me the clock all the time. I have it showing the screen in negative so the clock is highly visible in strong sunlight.
There is simply not one thing not great. I need to shop for a Sirius/XM add on.
This receiver has great sound. I just changed all four speakers to four-way Pioneer's. My little Ranger pickup sounds great.
Sitting in traffic on my commute is now awesome.

It is a little confusing at first if you haven't had an audiophile type head unit but once you get the hang of it you'll never want anything's ng else. The sound quality is amazing, and it seems to be clean clean even at high volume. It's best thing I've bought for my car so far.
