The main unit The main unit is the center of the car's audio system, usually located in the center of the dashboard. Head units give the user control over the machinery of entertainment media: AM / FM radio, satellite radio, CDs, tapes (although it is now rare), MP3, GPS, Blue Tooth, etc. Unit also known as a receiver.

Subwoofer subwoofer is a woofer, or a complete loudspeaker dedicated to the reproduction of low frequency sound.Subwoofer, also known as "subs", which used to extend low frequency performance of the main speakers. Subs Woofers are made by mounting one or more generally between 8 "and 21" in diameter in a well-braced wood or plastic greenhouse. Have a passive subwoofer driver active subwoofer and subwoofer enclosure have a built-in amplifier.

Amp-In general, an amplifier or simply amp, is a device that changes, usually increases the amplitude of the signal. The signal ""usually voltage or current. Amplifiers are made in both single-channel, 2-channel or multichannel configurations can be a sign of increasing to more than one audio component.

Capacitor, car audio capacitors are basically the power-efficient cars in the car. These capacitors accumulate that power which is necessary for the amplifier to produce a big sound. This effect is obtained when the demand for electric power capacity to power the vehicle is exceeded. You can listenbooming bass sounds and songs with this much-needed punch only because of audio capacitors. Car audio capacitors are also known as hardening capacitors.

Crossover Crossover-Audio is a class of electronic filters designed specifically for use in audio applications, especially hi-fi. Common uses of the power units are able to cross the entire spectrum of sound with luidheid acceptable and the lack of disturbance in itself. So CROSSOVER aim to divide audiosignal into different frequency bands used by each speaker drivers are optimized for the bands can be manipulated.

Treble-A small loudspeaker designed to reproduce high frequency sounds in a sound system high wedding. A triple is generally able to produce high frequencies around 2000 Hz to 20,000 Hz (20,000 Hz is generally considered the upper limit to the human ear).

Blue Tooth In short, the blue tooth technology allows a wire-lessly stream of digitalmusic from almost any audio player in another. Used mainly by experienced users and sophisticated car audio.

A car audio equalizer EQ can be a very realistic sound control is defined. EQ set the user to different frequency bands in a system of audio. The user can also view graphically or digitally (depending on the equalizer design) these frequencies using EQ. A normal car audio equalizer includes several audio filters or amplifiers.Each audio filter is centered on a given frequency range audio. The user can then decide which frequencies to be strengthened and must be rejected. It requires a level of skill.
