The Basic Details Of Car Audio

By Tim Kiv


Car audio is the term used to describe video or sound systems that are installed in vehicles. These systems have existed since the early days of radio when enthusiasts would adapt their domestic equipment to be used in their vehicles. There have been many different types over the years, including tape players that utilize reel-to-reel equipment, 8-tracks, compact cassette players and CD 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 vehicles of today, the main device of controls is called a head unit. This unit is placed in the center portion of the dash panel, which is between the driver and passenger seats. For older car models with the added audio, these control devices are mounted externally underneath or on top of the dash.

Speakers often include a space-saving design. For instance, the mounting of a tweeter over woofers or using non-circular cone shapes. A particular kind of speaker for low frequency reproduction is known as subwoofers. Motorcycles include similar equipment to give the driver a sound experience as well. Boom cars is the nickname given to cars that have loud sound systems that may violate local noise ordinances.

There are various components of these sound units in addition to the head units, subwoofers, stock units and speakers. An electronic car amplifier is separate from these systems. Although many head units have amps installed. These may be located elsewhere or not have the desired features or power wanted. External amps are an option if pre-installed devices prove inadequate.

Capacitors are the structures made to store the energy needed on demand by the amps. These units come in many different sizes, measured by farads. Damping involves the sound regulating components that are installed in the boot and trunk areas and doors of vehicles. The purpose of these is to damp the excess vibration that occurs within panels as a result o the subwoofer sounds. This is especially necessary in the trunk and boot areas. Multiple CD changers, car computer, audio processors, crossovers, gaming consoles, cables and controls are just some of the other system parts.

Car audio refers to video or audio devices found in cars. These units may be stock, installed by the manufacturer, or customized by the owner. There are numerous components to these devices including speakers, head units, subwoofers, controls, equalizers and more.
