The Basic Aspects Of Car Audio

By Tim Kiv


Car audio is the terminology used to defined the various sound and video systems that are placed within vehicles. These devices have been around since the first days of radio. At that time, enthusiasts would make adaptions of their domestic equipment to place in their cards. Over the years, there have been many different versions, such as tape players that use reel-to-reel set ups, compact cassette players, 8-tracks and compact disc players.

Stock units refers to the OEM, original equipment manufacturer, application that a vehicle manufacturer chose to be installed when the car had been built. Many stock systems have advanced in many ways. In fact, some of these systems do not require additional parts in order to enhance power and quality of the sound.

In modern vehicles, the main control device for these units is referred to as the head unit. This is installed in the center of a dash panel that is located between the passenger and driver seats. In older cars, that have the added option for audio components, these devices were mounted outwardly on the top or underneath the dash.

Speakers are designed to conserve space. For example, a tweeter may be mounted over a woofer, or non-circular shapes may be utilized. Subwoofers are a type of speaker that has a low frequency production. Even motorcycles include equipment that is used for sound purposes. Boom cars are the nickname given to vehicles with loud systems so powerful they violate some noise ordinances.

There are numerous components to these devices, aside from the traditional stock units, head units, speakers and subwoofers. A car amplifier, usually electronic, is separate from other elements of these systems. Most head units include amps, but some do not or lack the desired amount of power or features. External amplification is available for purchase if the installed units are not adequate.

Capacitors is the name given to the devices that store the energy needed by the amps. These structures are available in different sizes, measured in farads. Damping are sound regulating components that are often installed in the trunk, boot and doors. These are utilized to damping the panels vibration in the car that occurs because of the subwoofer sounds. This is especially common in the boot and trunk area of a vehicle. Other components of these systems: car computer, mobile video, audio processors, crossovers, gaming consoles, cables, multiple CD changers.

Car audio involves the audio or video devices that are placed in vehicles. These devices may be considered stock, manufacturer-installed versions, or owner customized. There are several elements to these units, such as head units, equalizers, controls, speakers, subwoofers and more.
