How To Install A Powered Subwoofer To A Factory Stereo

Installing a powered subwoofer to your factory stereo can greatly enhance the sound quality and bass in your car audio system. A subwoofer is a speaker specifically designed to reproduce low-frequency sounds, giving you that deep and full bass you desire. While many factory stereos lack this feature, adding a powered subwoofer is a simple solution to upgrade your sound system.

In this guide, we will walk you through the steps of installing a powered subwoofer to your factory stereo. We will cover everything from choosing the right subwoofer for your car, to wiring and installation. By following these steps, you can achieve a professional-quality audio system without breaking the bank.

Choosing the Right Subwoofer

Before beginning any installation process, it is important to choose the right subwoofer for your car and desired sound quality. Subwoofers come in various sizes and power ratings, so it is crucial to do some research and select one that will fit well with your factory stereo.

When selecting a powered subwoofer, pay attention to the size of your car’s trunk or available space for installation. Subwoofers come in different shapes and sizes, so consider the dimensions of your trunk and choose one that will fit without obstructing other components. It is also important to check the power rating of the subwoofer and make sure it is compatible with your factory stereo’s output.

Steps to Install a Powered Subwoofer to a Factory Stereo

Now that you have selected the right subwoofer for your car, let’s dive into the installation process. Follow these steps to successfully install a powered subwoofer to your factory stereo:

Here are the steps:

Gather all necessary tools.

Before starting the installation process, it is important to gather all necessary tools. You will need a power drill, wire cutters/strippers, crimping tool, screwdriver set, and a voltage meter. These tools will make the installation process smoother and ensure that you have everything you need at hand.

It is also recommended to have an installation kit specific for your car’s make and model. This will include all the necessary wiring and connectors, making the installation process easier.

Disconnect your car battery.

Before beginning any installation, it is crucial to disconnect your car’s battery. This will prevent any electrical issues or short circuits during the wiring process. To do this, find the negative terminal on your car battery and use a wrench to loosen and remove the negative cable.

Also, make sure to park your car in a well-lit and ventilated area for safety purposes.

Locate the factory stereo.

The next step is to locate your factory stereo. This can vary depending on your car’s make and model, but it is usually located in the center console or dashboard. Refer to your car’s manual if you are unsure of its location.

Once you have located the stereo, carefully remove it from its mounting by following the manufacturer’s instructions. This may involve removing trim pieces or unscrewing screws.

Connect the power cable to your car battery.

Now that you have access to the factory stereo’s wiring harness, locate a hole in the firewall of your car and use it to run a power cable through to the battery. Make sure to use a grommet to protect the cable from any sharp metal edges.

Connect one end of the power cable to the positive terminal of your car battery and secure it tightly with a wrench. This will ensure that your subwoofer is receiving enough power to function properly.

Connect the RCA cables.

The next step is to connect the RCA cables from your powered subwoofer to the factory stereo’s wiring harness. You can easily locate the RCA cables by finding the red and white connectors on the back of your stereo.

Connect the RCA cables to their corresponding colors, making sure they are secure and not loose. This will provide the audio signal from your stereo to your subwoofer.

Connect the remote turn-on wire.

Next, you will need to connect the remote turn-on wire from your subwoofer to the factory stereo’s wiring harness. This wire is responsible for turning the subwoofer on and off along with your stereo.

Locate the blue or blue/white wire in the stereo’s wiring harness and connect it to the corresponding wire on your subwoofer’s harness. This will allow the subwoofer to turn on and off with your stereo.

Mount the subwoofer.

Now that all the wiring is complete, it’s time to mount your powered subwoofer into your car. Refer to the manufacturer’s instructions for the specific steps on how to securely mount it in place.

Make sure to choose a location that will not obstruct any other components and has enough space for proper ventilation.

Test your subwoofer.

Once the subwoofer is mounted, it’s time to test it out. Reconnect your car battery and turn on your stereo. Play some music and adjust the bass settings to see if your new powered subwoofer is working properly.

If everything sounds good, then congratulations! You have successfully installed a powered subwoofer to your factory stereo.

Tips for Optimal Performance

To ensure the best performance from your new powered subwoofer, here are some additional tips to keep in mind:

  • Make sure all wires and connections are secure and not loose.
  • Adjust the gain and crossover settings on your subwoofer according to your desired sound quality.
  • Consider upgrading other components of your car’s audio system, such as door speakers, for a more balanced sound.
  • Regularly check the subwoofer’s fuse to prevent any electrical issues.

By following these steps and tips, you can achieve a professional-quality audio system in your car without spending a fortune. Remember to always consult the manufacturer’s instructions and refer to your car’s manual for specific details.
