Your car’s audio system can be complicated, and might even be a little overwhelming at times. If you’re leaving your car audio installation to an expert who knows best, you might think there’s no need for you to know how the system works. However, understanding your car audio system can not only facilitate the process, but help you make important decisions to achieve the sound you want.

In this guide, we’ll reveal how your car audio system works, and how to upgrade your vehicle with sound system installation at our stereo shop near you.


What Makes Up Your Car Audio System?


There are three essential components to every audio system, and each plays a vital part in transforming your sound. Learning more about each component can give you more confidence during your car sound system upgrade.


The Head Unit

Think of the head unit as the brain of your car audio system. Its main purpose is to provide an audio signal to the other components within the system. The head unit is also where the driver can control their entire stereo system right from their dash, from adjusting the volume to switching audio sources. Most head units also have tone controls that allow the driver to fine-tune their sound by altering the bass and treble.


Head units come in a variety of designs and capabilities. Most aftermarket head units feature convenient extras like Satellite radio, AUX and USB inputs, Bluetooth capabilities, GPS navigation, and smartphone connectivity. Some are even combined with infotainment systems that give you control of your sound system right at your fingertips.


The Amplifier

The amplifier acts as a power source for your car audio system. It also improves the overall volume and clarity of your sound, all while preventing distortion. An amplifier is already embedded within the head unit of most factory sound systems, but aftermarket car sound system upgrades usually require a larger, more powerful external amplifier for the best sound quality.


The Car Speakers

Speakers are the part of your car audio system that actually produce the sound. Although factory car speakers are “full range” and designed to produce the entire frequency range, they typically can’t match the quality that a separate component system can offer.


By installing multiple speakers that each work within smaller ranges of sounds, you’ll receive a much more accurate sound reproduction - and hear your music the way the recording artist intended. Each speaker is designed to produce a particular part of your sound, so installing each one separately will create a noticeable difference.


Subwoofers bring out low-frequencies and deep bass. Midrange speakers are made to deliver the middle-range frequencies. And finally, tweeters support the highest frequencies of your sound.


How Do They Work Together?

The head unit begins the process by sending audio signals to the amplifier. The amplifier then strengthens the signal so it’s powerful enough to move the speakers. Once the speakers receive the signal, the electrical energy is turned into mechanical energy, causing the cones inside the speakers to move back and forth. This vibration displaces air, creating sound waves that we’re able to hear.


The components of your car audio system depend heavily on one another to produce a more detailed, enhanced sound. And to truly get the most out of your car sound system upgrade, you’ll want to upgrade each component. You’ll never experience the maximum function or effects of an upgraded amplifier or head unit without new car speakers.
