What Are the Factors in Buying Best Under Seat Subwoofers?

Underseat subwoofers are essentially speakers that are placed under your seat to provide better bass and overall audio quality.

They work well for a variety of vehicles because they can be hidden out of sight until they’re needed. However, the main challenge with underseat subwoofers is their placement. In fact, there’s no universal standard regarding where you should place them, so you may want to do a bit of research before making any purchase.

Here’s a quick look at some of the most important aspects to consider.

Size & Weight

The first thing you’ll want to think about when purchasing an underseat subwoofer is size.

You’ll want to make sure that it fits in your vehicle’s console or trunk. You’ll also want to factor in how much weight it can hold.

It’s always best to get a model with a high quality speaker, so you don’t want to be forced to add a subwoofer just to have more power.

Frequency Response

When shopping for a subwoofer, you’ll want to consider its frequency response. It’s the range of frequencies that your subwoofer is capable of producing. The more bass a subwoofer can produce, the better. It will sound better than one that produces only low frequencies and is unable to fill the room with higher tones.

The best subwoofers will be able to produce a broad range of frequencies, from high-treble to low-bass. You can generally get a good idea of what type of subwoofer you need by looking at the spec sheet for your vehicle’s stereo system.

Audio Quality

Another important factor to consider is audio quality.

For most people, the best audio quality will come from a high-powered subwoofer with a sub-bass range of at least 100 Hz.

The higher the frequency range, the clearer and more detailed your music sounds.

However, many models will include sub-bass frequencies as low as 50 Hz or even 30 Hz, and there’s no real need for that level of bass. If you’re looking for clarity, you can get a subwoofer that’s more than capable of delivering.

On the other hand, if you enjoy listening to music at full volume, then you may want to opt for a subwoofer that has a lower frequency range.


You’ll also have to consider how much power you need for your underseat subwoofer. Most vehicles come with an aftermarket installation, so they will have built-in amplifiers to power their stereo systems. But if you’re installing a new stereo system, you’ll need to know the amp power that it requires. You may be able to find this information on the packaging for your stereo system.

Budget & Needs

If you’re on a budget, then you’ll want to consider what size and power range will work best for you.

If you’re on a tight budget, it might be best to go with a smaller model that delivers a moderate amount of bass. This will be good enough to satisfy most needs.

You may also want to consider the size of your vehicle when you’re buying an underseat subwoofer.

A larger vehicle usually requires a larger subwoofer, which means a higher price tag.

However, if you plan on upgrading to a larger vehicle in the future, then it would be smart to get an underseat subwoofer that will fit in your current vehicle and won’t break the bank.

Once you know what you need and what you can afford, you can narrow down your search to find the best underseat subwoofers that meet your requirements.


Is underseat subwoofer good?

Yes, underseat subwoofers are great. They can be used in any vehicle without the need for modification. They are generally easy to install and provide a deep bass output. In fact, they are even more powerful than regular car speakers, which makes them an excellent option for vehicles with limited space.

What size subwoofer is best for bass?

There are different types of subwoofers, each with their own specifications and features. But by our recommendation, the best type for a vehicle is a 12″ subwoofer. They’re relatively small and compact, with the power to deliver great sound and volume.

What makes a subwoofer hit harder?

A subwoofer hits harder when it has a higher volume output and greater bass response. These are also determined by its speaker size and quality. The bigger the size of the speakers, the more powerful they will be, and hence produce more bass. High-quality subwoofers are able to provide high-quality sound at lower volumes.
