What is a Subwoofer Box and Why You Should Get One 

A subwoofer box is basically just what the name says: a box or enclosure designed for your car’s subwoofers.   

Instead of mounting the subwoofers on your car, a subwoofer box is where you will install the subwoofers. As a result, the performance of subwoofers is improved. At the same time, the additional room helps improve airflow to minimize the risk of overheating. Lastly, subwoofer boxes are often designed to help improve the aesthetics of your car, especially if placed inside trunks. 

Types of Subwoofer Boxes 

There are four types of subwoofer boxes that you can choose from: sealed, ported, bandpass, and free-air.  


Sealed enclosures, as the name suggests, use a compact design with a single opening. The design lends itself to versatility as most subwoofers can easily fit inside one, and it fits in nearly every vehicle. However, because it doesn’t push air in and out of the box as much, you’ll need to play your speakers at higher volumes to notice the improvement.  


Ported subwoofer boxes result in a more powerful bass sound compared to sealed boxes. They’re also designed for better airflow that helps prevent overheating. This design is best used for those who like to listen to bass-heavy music, like rock, heavy metal, and other kinds of bass-heavy audio.  


A bandpass subwoofer box is usually a variation of a ported box. It’s usually used for dual subwoofers with one chamber open and the other enclosed. This is a design best for those who know what they’re looking for subwoofers. The sound quality is often described as aggressive and best for hard rock, rap, and reggae.  


Free-air subwoofer boxes usually use the trunk as the enclosure, with the subwoofer mounted on a board before it is attached against the rear seat. This minimizes the sound distortion commonly associated with subwoofers without boxes. They’re great and easy to install but only work if used with free-air subwoofers.  

Things to Consider When Picking a Loudest Subwoofer Box Design 

There are 4 major factors you should consider when choosing a subwoofer box design: the type of enclosure, size, available space, and aesthetics.  

Type of Enclosure  

Most of the time, sealed boxes are used because they don’t take up as much space, and they are fairly cheap. However, if you have more space available, you can enjoy better-quality music using a ported box. Meanwhile, bandpass boxes and free-air boxes are best used for subwoofers specifically designed for such purposes.  


The size of the box is determined by the type of enclosure used and how many subwoofers you want to fit. The closer the size of the subwoofers you’re using is to the size of the box design, the better.  

Available Space  

How much available space there is on your vehicle will also determine what kind of subwoofer box you’re allowed to use and install.  


Most manufacturers make subwoofer boxes with carpeted exteriors or slanted designs to help improve their look and make them fit better with the rest of your vehicle’s interiors.  

Final Thoughts 

Getting a subwoofer box isn’t for everybody. However, if you want to enjoy deep and loud bass, a proper subwoofer box is necessary. But, doing so is much easier said than done, which is why we recommend doing your research first. Then, hopefully, you can use our tips to help you find the best and loudest subwoofer box design for deep bass.
