The first-generation Mazda Miata, also known as the NA Miata, has earned a legendary status among car enthusiasts. One feature that makes this roadster stand out is its built-in headrest speakers. While they might seem like a small detail, NA Miata headrest speakers enhance the driving experience in ways many people overlook. This topic will dive deep into what NA Miata headrest speakers are, their purpose, how they work, how to upgrade or replace them, and why they remain a favorite among Miata owners.
What Are NA Miata Headrest Speakers?
Headrest speakers in the NA Miata are small audio speakers mounted inside the headrests of the car’s seats. They were introduced to make it easier for drivers and passengers to hear music while driving with the top down. Convertible cars often struggle with wind noise, and headrest speakers bring the sound closer to your ears for a more immersive and clear listening experience.
Why Did Mazda Include Headrest Speakers in the NA Miata?
The NA Miata was designed with the idea of Jinba Ittai,â or the feeling of unity between horse and rider. Part of that connection comes from enjoying the drive, and music plays a big part in that. When the top is down, traditional car speakers lose effectiveness due to wind and road noise. The headrest speakers solve this by delivering sound right behind your head, allowing clear audio without needing excessive volume.

Benefits of Having Working Headrest Speakers
1. Clear Audio with the Top Down
Whether you’re cruising on the highway or enjoying back roads, headrest speakers ensure you can hear your favorite tunes.
2. Lower Overall Volume Levels
Since the sound is close to your ears, you don’t have to crank up the main speakers, reducing audio distortion.
3. Enhanced Driving Experience
A top-down Miata drive with clear, immersive audio creates a memorable and enjoyable experience.
Custom Modifications for NA Miata Headrest Speakers
1. Adding Additional Speakers
Some enthusiasts add midrange speakers or tweeters to complement the headrest units for a fuller soundstage.
2. Installing Sound Deadening
Adding soundproofing materials behind the headrest area or around the door panels can reduce outside noise and enhance audio clarity.
3. Seat Reupholstery with Custom Speaker Enclosures
Custom upholstery with built-in speaker pods can make your interior look fresh and provide better sound projection.
Should You Keep or Remove Headrest Speakers?
Some NA Miata owners debate whether it’s worth keeping headrest speakers. The answer depends on how you use your car.
-
Keep them if you regularly drive with the top down and enjoy music during your drives.
-
Remove or skip them if you’re more focused on track driving or weight reduction and don’t need in-car audio.
Headrest Speakers vs. Door Speakers
While door speakers can offer better bass, headrest speakers are much closer to your ears, giving a unique sound experience that door speakers alone can’t match. A combination of both often results in the best audio setup.
Maintenance Tips for Headrest Speakers
-
Periodically check wiring connections to avoid crackling or loose sound.
-
Avoid moisture exposure, especially if you wash your seats or leave the top down in humid conditions.
-
Don’t play audio at maximum volume constantly, as this can cause speaker damage over time.
NA Miata headrest speakers are more than just a quirky feature; they are part of the driving fun that this classic roadster is known for. Whether you’re sticking with the factory setup or upgrading to modern audio components, headrest speakers can greatly enhance your open-air driving experience.
Replacing and upgrading them isn’t complicated, and with the right components, you can transform your Miata’s cabin into a mini concert hall â even with the wind rushing by. If you love cruising with the top down and want to enjoy your favorite music clearly, investing in good-quality headrest speakers is well worth it.
