Factors To Consider When Buying An Under-Seat Car Subwoofer
If you’d like to boost your default car audio system with an under-seat subwoofer, here’s what you should consider:
If you want deeper bass, a higher power handling by the underseat woofer is preferred. It needs to have enough power to convert electrical energy to sound energy. Hence, the higher the power rating, the more energy it can potentially transform into sound.
Almost all underseat subwoofers for cars come with a pre-built amplifier. Most class D amplifiers should be efficient and powerful enough to handle an under-seat subwoofer.
Additionally, take note of the power rating of the amplifier. The higher the better, as it will play louder.
The cone inside the subwoofer is the part that displaces air to produce the bass sound. The larger the cone, the more air it will displace. Therefore, choose a model with a bigger cone if you want a deeper and more powerful bass.
As an example, a 12-inch model will always produce a more powerful bass than an 8-inch model, no matter how good the 8-inch one sounds.
A subwoofer that is more sensitive will require less electrical energy to move the cone and produce a sound. Therefore, such a woofer is considered to be more power efficient than other models. Moreover, since it consumes less, it will also last longer since the components will heat less and are more durable over time.
If you want a clean install and do not want audio wires to be visible, then you must use thin wires for the connections. However, only subwoofers with a low impedance will accept thin wires. For discreet installations, a two Ohms subwoofer is always better than a higher impedance model.
The resonant frequency is the minimum frequency the subwoofer can respond before it distorts. Lower is better in this case, especially since an underseat subwoofer will be in a confined space where it is more prone to distortions. A lower resonant frequency should help massively in producing a clearer and cleaner sound.
The RMS power is the total amount of continuous power a subwoofer can handle. In fact, it is the most accurate measurement of the subwoofer’s power. As the RMS power handling increases, so will the loudness capability. It is important to note that it’s better to overpower than underpower any type of speaker.
The powered subwoofer is similar to the enclosed subwoofer, except that it includes an amplifier along with the subwoofer, which is stored inside of an enclosure.
These typically do not take up very much space, but most people tend to install them in the trunk or on the floor behind the driver’s seat.

It’s the baby version of a subwoofer, all encased in a single body. It is best for vehicles as it also has an amplifier built into it, without the hassle of wires.
Q: How do I choose a subwoofer?
Refer to our guide above for factors to consider. Your choice would depend on your car, your needs, and your preferences alongside the features the subwoofer can offer.

Q: What are the advantages of underseat subwoofers?
First, these are small, lightweight, and compact. They can easily be installed and removed and they will not negatively factor in your car’s performance or take up too much space. Second, they are cheap.
Q: What are the disadvantages of underseat subwoofers?
First, it could be inconvenient if you buy a large one, especially if you place it somewhere where people could be affected; like on the space people could’ve stretched in or slept. Second, being single and compact, their sound quality could be compromised.
Q: What’s the difference between underseat and trunk subwoofers?
Underseat subwoofers are lightweight, small, easy to install, highly portable, spaceless, and affordable. However, they are also not customizable, less durable, and more prone to wear and tear due to their placement.
Meanwhile, trunk subwoofers are customizable, more durable, and offers better sound quality than the former type. Additionally, depending on your preference, it could either be good or bad that it is heavier and comes in bigger sizes. The downside is that it costs more.
