Editing Vehicle audio (section)

==Components and terms==
The stock system is the [[OEM]] application that the vehicle's manufacturer specified to be installed when the car was built.

Aftermarket components can also be used.

* [[Head unit]]: Headunit products includes the screen and buttons and are manufactured mainly in DIN form factor, which refers to [[ISO 7736]]. Head units come as single DIN or double DIN.
* Connectors for car audio, where ISO 10487 Harness Adapter is used.
* [[Capacitor]]s.
* Mobile [[audio power amplifier]]s.

Amplifiers increase the power level of audio signals. Some head units have built-in stereo amplifiers. Other car audio systems use a separate stand-alone amplifier. Every amplifier has a rated power level sometimes noted on the head unit with the built-in amplifier, or on the label of a stand-alone unit.

# Coaxial speakers: These are the most common type of car speakers and are often factory-installed. They usually consist of a woofer and a tweeter mounted on the same axis, and are designed to reproduce a wide range of frequencies.
# Component speakers: These speakers are designed for higher-end car audio systems and typically consist of separate woofers, tweeters, and crossovers. This allows for more precise sound tuning and a higher level of sound quality.
# Subwoofers: These speakers are designed to reproduce low-frequency sounds, particularly bass. They come in various sizes and power levels, and can be used to enhance the bass in a car audio system.
# Mid-range speakers: These speakers are designed to reproduce mid-range frequencies, such as vocals and instruments like guitars and pianos.
# Tweeters: These speakers are designed to reproduce high-frequency sounds, such as cymbals and other high-pitched instruments.
# Sound-deadening material is often used in the door cavities and boot area to dampen excess vibration of the panels in the car in response to loud subwoofer bass tones, especially the boot (trunk).
