Why Under Seat Subwoofers?
The underseat subwoofer is an oddly shaped speaker that enhances low-frequency sounds (below 50Hz). It does this by transmitting an electric signal to the amplifier which then amplifies it.
This process improves the bass sound of the speaker making the audio more engaging. Also, under-seat subs provide a more immersive audio experience.
Because of its compact size, it fits well in mid-sized cars and pickup trucks. All you need to do is install it under the seat and enjoy its benefits.

Best Under Seat Subwoofer Buying Guide (Important Factors to Consider):
Size:
When thinking about hiding a subwoofer under car seats, it is important to consider its size. Before buying a subwoofer make sure you measure under the seat where it’s going to be placed so that it fits properly. Here are the standard dimensions of compact subwoofers for cars.
8-inch Subwoofers:
This is currently the smallest car stereo available which delivers good sound quality with great features without taking much space. It can reproduce low frequencies without compromising on audio clarity.
10-inch Subwoofers:
If you want your subwoofer to fit under the car seat then this is the best option for you. These subwoofers provide excellent bass response and clarity beating other subs in this category by far.
Power Rating:
When searching for a new subwoofer, power rating must be taken into consideration. There are two values that are key – RMS and Peak. Both these figures matter but for different reasons.
RMS (root mean square):
The RMS value indicates maximum continuous power that can be handled by a subwoofer without any distortion in the sound produced; this rating sets an optimum performance level below which the device should never go beyond during usage.
Peak power:
Peak power measures the maximum amount of energy small car subs can handle over short periods of time; if the external amplifier is being used ensure compatibility with the rated output.
Sensitivity:
Subwoofer sensitivity shows how much energy is required to move the cone and generate sound. The higher the sensitivity, the less power will be needed for sound production thus making it more power-efficient which in turn increases its lifespan due to less heat being produced over time.
Frequency Response:
Human hearing range is between 20-20k Hz with bass sounds being felt around these frequencies by our ears. Therefore, subwoofers are made to produce audible vibrations at or below 20Hz.
Frequency response should be considered when choosing small car subs because ideally speaking anything around 100 Hz or lower would produce better sound and work effectively.
Higher frequencies tend to create distortion, hence low is better.
Passive vs Active Subwoofers:
Both types of subs look similar but differ mainly on one point – active subs have built-in amplifiers while passive ones do not.
An active subwoofer consists of an internal amplifier that powers the speaker and produces sound whereas a passive one relies on an external amplifier for driving power into speakers.
Active subwoofers are good for smaller cars or places where you want to save space; they require less wiring and take up less room than their counterparts
On the other hand, passive subwoofers require an extra amplifier, which means more space is used. But you can connect a powerful amplifier for a better listening experience with a passive subwoofer.
Easy Installation:
The best under seat subwoofers are small and lightweight. Ensure that it is compact and easy to install without professional help.
