Driving around with a subpar car audio system can be a drag.

If you’re not happy with the sound of your audio system, it’s probably time for an upgrade. Contrary to popular belief, you can actually improve your audio system affordably with just a few key components. You just need to know what to get.

In this post, we’re going to look at different car audio system components so you can select the right ones for your car. It can be overwhelming to improve a car sound system if you don’t know much about audio equipment in general, so keep reading and let us teach you the basics.

The Head Unit

Your head unit is one of the most important components for car audio system functionality. It’s the thing you use to select music, adjust sound settings, and control various other aspects of your car (GPS navigation, Bluetooth, Apple Car Play, and Android connectivity).

When you buy an aftermarket head unit, you’re getting something with much more power and quality than the factory-built one. Car manufacturers will often use cheaper components to save money on production. One thing to remember is that you’ll need to ensure that your head unit is compatible with the rest of your system before you buy.


Some cars have great factory speakers, but it’s pretty rare. If you’re an audiophile, then upgrading your car speakers is a no-brainer. Going to a site like bigjeffaudio.com will give you all the speaker variety that you could ever want.

The first thing you’ll want to do is try to get the right-sized speakers for your car. Simply use a tape measure to find out what size your current ones are, then shop for a similar size.

The nice thing about trying to upgrade your car sound system is that you don’t have to replace everything at once. Start with your front speakers and work your way backward as your budget opens up.


We’ve all heard cars with great subwoofers before – you can hear them coming a mile away. While it may not sound great on the outside when the subs are thumping, it makes for a wonderful audio experience.

Your subwoofer will often sit in the back of the car and provide all of the low ends that you need when listening to music. If you want a well-rounded sound system, then get a good subwoofer.


Most head units come with a built-in amplifier, but you can upgrade this as well. The amplifier lets you listen to your music louder without it pushing the speakers too hard. This is better for listening and much better for the longevity of your sound system.

Get the Right Car Audio System

Now that you know how to upgrade your car audio system with the proper components, you can start shopping for speakers, subwoofers, and head units. Once you’ve got a good car audio system, you’ll revolutionize your drives to work, school, or road trips.
