Why Underseat Subwoofers?

The underseat sub is an unusual shape of a subwoofer that amplifies the low-frequency response – the frequencies below 50Hz – of a speaker. The subwoofer sends the electrical signal to the amplifier, which boosts it. The amplifier then adds low-frequency information to the original signal, which is then sent to the speaker. The result is a louder sound with better bass.

Its capacity to dampen vibrations and produce high-quality bass sound is something no one would imagine. It’s ideal for cars and compact trucks. It is fixed beneath the driver or passenger’s seat. However, it’s not just the location that makes these subs unique. Let’s take a closer look at what makes them stand out from the crowd of top-rated under-seat subwoofers.

Best Under Seat Subwoofers Buying Guide (Important Factors to Consider):

Now that we have discussed the 10 best under seat subwoofers with pros and cons, and advantages and disadvantages of small car subwoofers, there are a few important factors you need to consider before you make the ultimate choice. Let’s have a look at them:

Size:

Subwoofer size is an important consideration because it determines whether or not you can put one under the seat. Be sure to measure the space under your seat before making a purchase. Small car subwoofers typically come in the following sizes:

8-inch Subwoofers: This is the smallest car stereo you can get and it still has all the great features you need for great music. Without sacrificing clarity, they can provide deep bass. If you’re searching for a subwoofer that’s not going to blow your socks off, these tiny subs are a great option.

10-inch Subwoofers: If you’re looking for subwoofers that can fit beneath your seat, this is the one to choose. In terms of bass and clarity, these subwoofers prove to be the best compliment to any sound system. These subwoofers are a great replacement for 8-inch subwoofers, as they are compact and easy to install, while still delivering high-quality sound.

Power Rating:

When shopping for a new subwoofer, it’s critical to consider the subwoofer’s power rating. RMS and Peak are the two power figures. There are several reasons why each is significant. It varies from model to model in terms of the subwoofer’s power. Choosing the right speaker for your system is easier if you know its RMS and peak power. Let’s take a closer look at them both.

RMS (root mean square): RMS tells us about the amount of power a subwoofer can handle continuously without causing sound distortions. If you use the subwoofer within the prescribed RMS rating, you will get exceptional results. Otherwise, you may end up damaging the subwoofer. 

Peak power: Peak power tells us about the maximum power small car subwoofers can handle in a short time. 

If you are using an external amplifier, make sure that the power rating is compatible with the amplifier otherwise you may damage the subwoofer permanently. 

Sensitivity:

Sensitivity refers to how much energy the subwoofer needs to move the cone and produce sound. The higher the sensitivity the less energy it will require to produce sound. 

Such a subwoofer is more power-efficient and has a long life due to less heat production over time. 

Frequency Response:

Human hearing ranges from 20-20k Hz and our ears can detect bass sounds around these frequencies. That’s why subwoofers are designed to produce audible vibrations around 20Hz or more. 

Frequency response is vital to consider while selecting the small car subwoofers. Ideally, around 100 Hz or less subwoofer produces better sound and works efficiently.

Higher frequencies tend to create distortion, hence low is better. 

Passive vs Active Subwoofers:

The only difference between both is that one has a built-in amplifier whereas the other doesn’t have a built-in amplifier. 

The active subwoofer comes with a built-in amplifier. In contrast, a passive subwoofer doesn’t come with a built-in amplifier. 

For small cars, active subwoofers are a better choice because they save space and need very few wireworks. 

Whereas, Passive subwoofers need an external subwoofer which consumes more space. But with passive subwoofers, you get the option to install a powerful amplifier to get a next-level sound experience. 

Ease of Installation:

The best under seat subwoofers are manufactured keeping portability and compactness in mind. The subwoofer you have decided to purchase needs to be compact and easy to install without the help of an expert.

Conclusion:

The underseat subwoofer is one of the most important parts of the car which is likely to impress you when it comes to the high-quality sound system. All of the mentioned models have a great sound, and they are easy to install. You will be able to install any of the models in less than 30 minutes. The bottom line is that the small car subwoofers we’ve shown you are all great subs, and you’ll be happy with any of them.

In the end, it is most important that you think about what you need from a subwoofer before you go out and buy one. If you’re putting it in a small space, you may not need a lot of power. If you want a lot of bass, you may want a subwoofer that puts out a lot of power.

Remember, there are a lot of factors that go into what makes a subwoofer great for your car. Do your research, read reviews, and consider what sound you are looking for. You can also comment on any query you have. We are always happy to help our readers find the best products for them!
