The Kenwood KSC-SW11 is a popular solution for car owners on a budget. This model is an all-inclusive solution that packs a powerful 150 Watts pre-amp that powers an 8-inch cone. Since the cone is small, it vibrates more and produces a punchy bass that is harmonious.

There are many likable features in this particular under seat subwoofer. For one, it has a massive 800 Watts power handling that shows that it can play loud when it has to.

#4. Kicker 11HS8 8" Hideaway Car Audio Powered Subwoofer
Editor's Rating: (4.1 / 5)
The 11HS8 from Kicker has been built specifically for tight spaces. Indeed, it is a compact and very low profile under seat car subwoofer that also happens to look amazing. And as expected from Kicker, the build quality in this woofer is exceptional. It is solidly built and is durable and long-lasting.
The only caveat we have is that this model is powered by a smaller 8-inch cone. However, it has a powerful 150 Watts amplifier that powers this under seat car subwoofer and produces a clean bass without any distortions.
Moreover, this model has a spider design that is known for its high efficiency and performance. Therefore, even if the cone is a little smaller than in the Rockville RW10CA, we can still expect above average sound quality mostly because of this efficiency.
All in all, if you want an extremely compact under seat car subwoofer that sounds phenomenal then it is difficult to beat this model from kicker on a price to performance ratio.
#5. JBL BassPros SL - JBL 8" RMS Powered Under Seat Compact Subwoofer
Editor's Rating: (4.7 / 5)
While the JBL BassPros is not the most powerful in terms of power handling with only 125 Watts, it is one of the most efficient and well built and the seat car subwoofer in this review. Notwithstanding that it is an exceptionally good-looking subwoofer. A shame that it has to go under the seat.
To make it even more irresistible, the JBL BassPros has many outputs at the back that allows the user to customize the bass based on his or her music preference.
Furthermore, due to the efficient design, this woofer will remain cool to the touch even when it is played at high volumes. Therefore, this drastically reduces the risk of a fire and makes this model very safe to use.
It still has a regular 8-inch cone inside, and even if it is small, it is punchy and deep and better sounding than most models in this review. Indeed, if we had to crown one model as being the best under seat car subwoofer then it would definitely be the JBL BassPros.
How to Buy an Under Seat Car Subwoofer
Before you can get the best hideaway subwoofer for the money, there are some important factors to consider. Here they are:
If you want a deeper bass, a higher power handling by the under seat woofer is preferred. The subwoofer needs to have enough power to convert electrical energy to sound energy. The higher the power rating, the more sound energy it can potentially transform.
Almost all under seat 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, of course 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-inches model, no matter how good the 8-inch sound.
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 2 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 under seat 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.
We've discovered that there are several types of under seat car subwoofers that vary in size, shape, and price. If you have a small car and still require a decent bass, this type of subwoofer will definitely fit the bill. Don't let its low-profile and compact form factor fool you. They are quite powerful.
However, keep in mind that the best under-seat powered subwoofer does not have to be the most expensive one or have the biggest cone. Choose one based on your preference, budget, and need.
