Best Small and Compact Subwoofer for Car (Buying Guide)

We can argue over the fact that bigger subwoofers sound blasting, but don’t underestimate the capability of compact ones.

Always remember the best subwoofer brings out the best in any sound system; despite how awful it tends to produce sound, the subwoofer just makes everything right and on track. But there are other things that you need to consider even while getting the best small subwoofer for car.

Let’s briefly discuss what makes the subwoofer good and worth buying.


The type of enclosures can let you decide what kind of music you can get to listen to. The ported enclosures bring the booming rock bass, and the sealed box is perfect for classical music due to its balanced sound projection. However, if you are a fan of solid and hard bass hits, get your compact subwoofer fit in a bandpass box for hard low frequencies.

Where to Put?

Whether smaller or bigger, the subwoofers require an ideal spot to perform and stand out in the room. When we talk about the subwoofers for home, we recommend putting them against the wall to add volume, and the corners are just perfect for subs to perform. However, in this scenario, we don’t have much choice with the car subwoofer.

Still, put it in the car trunk at the side if you can. Since it needs ventilation to stay cool and calm and not break during the long-playing times, the trunk would suit best. In other cases, we have added the best subwoofer for small cars that you can adjust underneath the rear seats or control from the driving seat.

Good Vs. More Bass?

The last thing to notice about the car subwoofers is, what do you actually want? You want to enhance the music system and something loud to hear while driving?

Well, if you have heard the thump-thump from other cars, it’s not a quality sub you are hearing; it can cause disturbance because the clarity will be long gone, and it would be a mixture of noises with distortions.

So, always choose quality over volume or other stuff. Small subwoofers can vouch for producing richer and deep low frequencies so you can enjoy every bit of it while not compromising the overall sound quality.
