Let’s jump into the step-by-step instructions so you can follow along:

1. Choose coaxial car speakers and accessories

First, you will need to find and purchase coaxial speakers that fit your car and budget. One great place to start is our vehicle fit guide, which will help show you what speakers you need for your vehicle. Depending on your vehicle, you may need a speaker adapter bracket to mount the new aftermarket speakers properly. You will also need the plug and play adapters to easily install your new speakers.

2. Disconnect the negative battery terminal

Once you have your tools, speakers, and necessary accessories ready to go, you are ready to begin! To prevent shorts, blown fuses, and other electrical issues, disconnect your negative battery terminal before starting the installation.

3. Carefully remove the door panel

Most door panels will require you to unscrew multiple screws along the edges and pockets of the door panel. Make sure that all screws are removed before moving on to the next step in this process. Once they are all removed use your panel removal tools to remove the door panel itself. It is possible to remove the door panels without these tools, but you need to be very careful to not break any plastic clips that help hold the door in place. Do not lose any of the screws or clips that hold in your door panel, because you will need to reuse them when you put the door back together. On two-door vehicles, you may need to remove your rear seat first when replacing the rear speakers. Some seats can easily be taken out while others may have bolts that need to be loosened. 

Take out your old speakers

4. Take out your old speakers

Some factory speakers will be held in by just some Phillips screws, while others, that will require you to remove the entire bracket, may be held in by bolts. If your speakers are held in by screws, use a Phillips screwdriver to remove them. If they are held in by bolts, use the correct size socket with your ratchet to remove them. Make sure to keep track of the hardware from your speakers because you may need to reuse them. Now just unplug the speakers from the factory harness.

5. Install your new coaxial speakers

When using the plug and play adapter this process is incredibly simple. Just slide the female quick disconnect onto the corresponding speaker connection. Make sure polarity is correct and you have positive on positive and negative on negative. Also, be sure the quick disconnect is on the connection nice and snug. If it’s slightly loose, use some needle nose pliers to slightly pinch it so it will not easily fall off. The nice thing about these plug and play adapters is that you can just snap the adapter to the factory plug and you are done. After that, screw your speaker back place using the provided screws. Also Installing some sound damping in the speaker locations will be a great way to reduce any rattles that these new speakers may create.

6. Test your new speakers

Before re-assembling your door panels, re-connect your negative battery terminal to ensure your newly installed speakers are working and sound great. Play some audio and adjust the balance to hone in on each speaker. Once you have confirmed that the new speakers are working and sound as expected, you are ready for the next step.

7. Replace the door panels and seats

Start by putting your factory panels back in place. Ensure that the panel clips are attached to the factory panel itself. Snap the panels back in place and screw in all the screws. Put your seat back as well if you removed it to access the speaker’s location. 

There you have it! If you followed these steps exactly, everything should be working properly and back in place. For extra help watch this step by step video. For more information on car speakers, just visit our car speakers category.
