So you don't have enough space inside your vehicle to accommodate larger subwoofers? Well, you don't have to feel left out, because under seat subwoofers can get the job done just fine.
Under seat subwoofers feature a very compact design. They can easily fit into tight spots. Their relatively easy installation and tiny size make them suitable for vehicles with very limited space such as compact hatchbacks and sport cars.
That being said, keep in mind that under seat subwoofers won't produce ground-pounding bass by any means. However, these subs are a great add-on to factory stereo systems.
Although these subwoofers aren't going to turn your ride into a rolling thunderstorm of bass, they'll certainly add some depth and punch to your music.
So, if you're wanting to add some bass without compromising space, consider an under seat subwoofer.

Alpine is a Japanese electronic component manufacturer that specializes in car audio equipment. They were founded in 1967.
They are, and always have been one of the most recognized brand in in car audio industry.
Alpine offers a wide range of quality products including car speakers, amplifiers, headunits (both single and double din stereos) and subwoofers of different types.
The PWE-V80 by Alpine is one of the best under seat subwoofers on the market. It's also one of the most expensive. However, this is a very well-engineered slim subwoofer and would be a great investment for anyone who's looking for a solid ready-to-use subwoofer that's designed with quality in mind.

The PWE-V80 has a variable low pass filter of 50Hz - 100Hz. It comes with speaker-level and RCA inputs, as well as a phase selector switch. A wired remote control is also included.
In terms of cons, it's really difficult to think of any. If anything, I'd say that this slim under seat subwoofer is a bit pricey.
However, something this good is naturally expensive. Our purpose here isn’t to convince you folks to go out and splurge on the most expensive under seat subwoofer.
Quite honestly, this subwoofer isn’t even close to the most expensive powered subwoofers we’ve seen.

They've been around for a very long time. They have made a name for themselves in the audio industry developing and marketing a wide array of audio equipment including car speakers, subwoofers, amps, head units as well as Hi-Fi home and personal audio, and amateur radio ("ham") equipment.
The Pioneer TS-WX130DA is one of the best selling powered under seat subwoofers on the market. It's very reasonably priced, and it would be a great solution to anyone who's wanting to further enhance the bass in their system without taking up a lot of space.
The TS-WX130DA incorporates a 8 inch subwoofer powered by 160 watts RMS by the built-in amplifier. This compact powered enclosed subwoofer features a very high sensitivity rating of 95 dB.
Which is quite impressive. And as a matter of fact, a subwoofer with high sensitivity rating requires less power to play louder than a sub model with lower sensitivity.
The TS-WX130DA comes with a wired remote control so you can adjust the bass from the driver's seat.
Although, the TS-WX130DA is designed specifically for cars, I don't see anything wrong if you use it in home theaters or media rooms to ensure that every chunk of music you hear reaches its full potential and simulate movie going experience.

Kicker is one of the most legendary when it comes to clear-sounding, ground-pounding bass.
They produce some of the best hard-kicking car subwoofers on the market, and the "Hideaway Compact Powered Sub" is no exception.
It's one of the best compact powered subwoofers under $300. The KICKER Hideaway Compact Powered Subwoofer delivers surprising low frequency output from a remarkably small enclosure, setting a new standard in plug-and-play bass performance and convenience in a vehicle.
At just about three inches high and nearly 14 inches long, the Hideaway houses a 150-watt built-in class D amplifier and an 8-inch heavy duty subwoofer to add decent thumping bass to any vehicle from the tightest spots.
It comes with a quick-connect power plug and Velcro®-fastened nylon straps for smooth, secure installation and simple but fast removal.
The quick-connect plug and harness entails power, signal and remote turn-on. The Hideaway also comes with a remote bass control so you can easily fine-tune bass levels on the fly, variable +6dB bass boost, adjustable low-pass crossover, two automatic turn-on options and a phase-cancelling switch for max output.
It also features high- and low-level inputs for smooth integration with nearly any aftermarket or factory single or double DIN head unit.
The only downside I can reasonably think of is the price. The Kicker Hideaway is a bit expensive.
However, there are still quite a few people we'd recommend this to. First, like all slim powered subwoofers, the Kicker Hideaway is geared to the needs of people with very limited space in their vehicles.
The Kicker Hideaway will save you the hassle of finding the rights enclosure and amplifier for your subwoofer, wiring, and matching the amplifier to the sub ...etc.
Additionally, the Kicker Hideaway is an all-in-one unit, so there's only one equipment you'll need to find a mounting place for.
All in all, Kicker Hideaway is one of the best small subwoofers, and when you pick it up, you'll know where the extra dollars went.

You may be asking yourself what this amplified subwoofer is doing on the list.
It's clearly outclassed by most small underseat car subwoofers we included here. So, why did we list? Price.

Pros and Cons of Under Seat Subwoofers
First off, the pros: one of the biggest pros of underseat subwoofers is their size. You can mount an under seat subwoofer almost anywhere inside your vehicle.
These small subwoofers are designed to fit within the space constraints presented by some compact vehicles. Additionally, they are light and portable, so you'll be able to easily to move or transport your under seat sub outside the vehicle.
In terms of cons, the lack of booming bass if one of the major drawbacks of these subs. Obviously, you won't get the same bass quality with these subwoofers as you'd with larger subs, and that's mainly due to their smaller drivers (sub and amp).
Most under seat systems are fitted with smaller subwoofers – particularly 8" inch subwoofers. Additionally, the built-in amplifier isn't anything to write home about compared to external powerful amplifiers.
Final Thoughts
The secret to feeling that hard-hitting bass on your daily drives without filling your car up with wires is installing an underseat subwoofer.
Thankfully, you now have a list of some of the best on the market.
So, what are you waiting for?
Take a close look at what these under seat subwoofers have to offer and start enjoying that gut-feeling and booming bass.
