What to look in the best subwoofer box for SUV

Most subwoofer boxes offer similar basic features. As such, it can be challenging to choose one that best suits your needs.

But, what makes one subwoofer box better than the other?

I. Material of the subwoofer enclosure

This is one of the primary considerations when buying, or building a subwoofer box. The material used to make a sub enclosure plays a great role in the final output of your speakers, and it can make or break your entire audio system. Overall MDF (Medium Density Fiberboard) is the best material for making subwoofer enclosures for several reasons. The wood is thick and durable, and it helps bring out the best sound from the sub. Other alternatives that are worth considering include, Plywood, pine wood, fiberglass, Lexan, among others. Ideally, your choice of material will depend on the bass performance, ease of customization, and price.

II. Choosing between ported vs. sealed subwoofer box

Typically, the style of bass you prefer is going to determine type of subwoofer enclosure you get. A ported subwoofer box uses a vent/port to allow free movement of air in and out of the box. This produces bass that is louder, boomy, but less accurate. On the other hand, a sealed enclosure is designed to be airtight, and it is ideal for those who prefer tight and accurate bass. Additionally, sealed enclosures are typically smaller than their ported counterparts, and they require more power to produce louder bass.

III. Size of the subwoofer box

Apart from the type of enclosure, it is also important to focus on sizing. As stated, sealed enclosures are small in size, making them ideal for small cars with limited space to spare. On the other hand, if you have enough space in your car, then you can consider a larger, dual subwoofer box that’s capable of moving more air. Equally important, the size of the sub box will largely depend on the size of subwoofer you have. For instance, if you have a 12-inch subwoofer, then you’ll need to for a box with a 12-inch diameter cutout.

IV. Buying or building a subwoofer box

For most people, getting a premade subwoofer box is more appealing considering the cost, and time it takes to build a box. Building the box from scratch will require you to have the right material, tools, and ample knowledge about planning and building a subwoofer box. Besides, premade boxes are readily available, and they come in different sizes to suit your specific needs.

On the other hand, a custom subwoofer box offers a more personalized experience, but this is going to take some time and expertise. Building your own box also allows you to get the right fitting as well as adjust various components when necessary.

Our Final Thoughts!

We unanimously think QPower QBOMB12VL is the best subwoofer for SUV if want premium features for such a premium price.

On the other hand, American Sound Connection dual 12” vented stereo sub box and Rockville REC97 are quite comparable to QBOMB12VL, and they offer a good value for the money.

You may also want to consider the single units if you don’t have a lot of space for the sound system, or for those with smaller vehicles. They are designed for optimal bass response and when matched with the right sub, they offer an improved listening experience.
