How to Install Aftermarket Car Audio System

Car Audio System

The quality of your car’s audio system can be considerably enhanced by installing an aftermarket system. An aftermarket system can improve the sound in any way you want, whether with deeper bass or crisper highs.

This article will walk you through installing an aftermarket care audio system, from picking suitable components to connecting everything. Before we can start, you’ll need a few simple items, including a screwdriver, pliers, and electrical tape.

Choosing the Right System

Head units, speakers, amplifiers, and subwoofers are just a few components that makeup aftermarket automotive audio systems. First, you’ll need to determine which aftermarket car audio system would work best in your vehicle. Consider your vehicle’s make and model, financial constraints, and musical tastes when settling on an audio system.

You can select between a single-DIN or a double-DIN head unit. The most common features of single-DIN head units are a CD player and an AM/FM radio. In contrast, double-DIN head units frequently include a larger touch screen and additional functions like Bluetooth, GPS, and a rearview camera.

Several options are available for speakers, including component speakers, coaxial speakers, and subwoofers. Component speakers are preferable since they have both a woofer and a tweeter, but not combined. For a lower price and less hassle, you can get wideband speakers.

Adding subwoofers to your car is a terrific way to get deeper bass from your music, but they will require additional cargo room. You can get increased volume and enhanced sound quality by adding an amplifier. You’ll have to run some more wires if you want to put the amplifier in the trunk or another location in the car.

Removing the Old System

To replace your car’s factory stereo with an aftermarket one, you’ll need to start by taking it out. A screwdriver or trim tool will be needed to remove the trimming pieces that enclose the original head unit. If you want to reuse the screws and moldings, keep track of where you put them.

After the inside panels have been taken off, the OEM stereo‘s wiring needs to be removed. The wiring harness on the back of the radio needs to be disconnected to accomplish this. To successfully install the new stereo, you must first know which wires belong to which components.

Installing the New System

After the old stereo has been removed, the new one, including the head unit, speakers, amplifiers, and subwoofers, can be installed. When installing an aftermarket system in your vehicle, the specifics will change based on your vehicle’s model and the specifics of the system you’ve chosen.

To get started, you must first put in the new control head. The head unit can be mounted on the dashboard after the wiring harness has been connected to its rear. A dash kit can conceal the space between a double-DIN head unit and the dashboard.

After that, put in the speakers. Speakers can be mounted in the doors or dashboard and connected to the head unit. If you want your speakers to sound their best, you should install them according to the manufacturer’s recommendations.

Installing an amplifier requires connecting the head unit to an external power supply and speaker wires. The amplifier can be installed in the automobile, such as the trunk. Installing an amplifier allows you to wire speakers directly into it.

Finally, if you’ve decided to put a subwoofer in your car, you’ll have to figure out where. The subwoofer is often installed under a seat or in the trunk. After setting up the subwoofer, you may connect it to the amplifier using the included cables.

Finishing Up

Once the new parts have been installed, the audio system should be tested to ensure it is operating correctly. Start the car, play music to evaluate the audio system, and fine-tune it if necessary. If your aftermarket stereo is malfunctioning, check the manual that came with it.

You can upgrade your new stereo with Bluetooth and a rearview camera if you want. You can add these features if you buy the right parts and follow the instructions.

Remembering the significance of system upkeep is also crucial. To maintain the system running smoothly and for as long as possible, it is important to clean it regularly and to use the correct wiring and connections.

Can Installing an Aftermarket Car Audio System Help Save Car Battery when Listening to Radio?

Installing an aftermarket car audio system can indeed help save car battery when listening to the radio. Upgrading to a more efficient system can reduce power consumption, ensuring a longer battery life. To learn more about how to listen to radio without draining the battery, consult with a professional car audio specialist.

How Long Does It Take To Install a Car Stereo?

The length of time required for installation shifts with each vehicle and each job. It takes around an hour to do a basic installation, but you’re looking at several hours of work for most cars. Once you buy a deck for your car, time is needed to remove the deck from your old vehicle and install it in your new one.

The installer shouldn’t be making a fortune on labor costs at your expense. Typically, installers will need between three and four hours to finish a work, while longer times can incur additional costs.


The quality of your car’s audio system can be considerably enhanced by installing an aftermarket system. Buying and installing an aftermarket automobile audio system is a breeze if you follow the advice in this article. You’ll be listening to your brand-new stereo system in no time, with only a little time and some simple equipment.
