Receiver SizeSingle 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.
Faceplate SecurityDetachable / 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 FaceplateSome 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.
Peak Power OutputThis 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 OutputThe 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.
17 watts x 4 channels
Preamp RCA OutputsRCA 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.
Dedicated Subwoofer Preamp RCA OutputA 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 VoltageThe 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.
Built-In EqualizerThe 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.
3-band graphic equalizer
Display TypeThe 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 ColorThe 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.
CD Signal-to-NoiseCD Signal-to-Noise Ratio is a key specification that is often overlooked by newbies. The CD S/N Ratio measures how well the CD player silences background noise. Higher ratings in decibels (dB) indicates less noise, and generally a cleaner signal.
