The unique thing about this product is that you can modify the high/low pass filter on each channel (25Watts per Channel), 10 Band Parametric Equalizer (+/-14dB @ 100Hz) which can fix any tone distortion issues at low frequencies due to outreaching distances between woofer cones (upgraded from earlier models).

Size: 13.5” x 3” x 9”
Power: Peak: 240 watts RMS: 120 watts
Woofer Size: 8”
Frequency Response: 32-150 Hz

Alpine is a reliable name among audio equipment manufacturers. Its PWE-S8 is among some of the best under-seat subwoofers available right now. For starters, this sub is the size of a legal pad, making its installation under or behind seats possible.

Moreover, its 8” woofer cone and D-class 120W amp are enclosed in a rugged die-cast aluminum casing. This durable and heat-dissipating construction makes it a suitable option for under-seat installation.

PWE-S8 works perfectly fine with both factory-fitted and aftermarket stereos. Moreover, you can use it with both RCA and speaker-level inputs. The sub also comes with a 15’ wired remote knob. You can easily install it on the dash to adjust the bass level of the sub right from the driver’s seat.

RMS: 50 W, MAX: 150 W

Frequency Response: 20-200 Hz

A Pioneer product will always be as you expect it to be; decently adequate and one hell of a performer. The Pioneer TS-WX130DA is exactly that and a lot more. It is not only economical, but it also delivers clean, deep, and seamless sound.

If your audio needs are pretty average, this sub will blow your boots off. It produces mountains of bass; however, don’t expect this little fella to shake the ground.

What it offers is just enough to keep a majority of people going and it does so at a decent price. Its aluminum cone comes fitted right in the middle of a urethane surround. This filters out the sound to give smooth yet surprisingly deep results. To keep things even more interesting, it features a 150 Watt amplifier which pushes this bad boy’s limits even further.

This package is not only easy to install, but its compact body also offers you an array of options on where you could fix it up. Sound manipulation with the Pioneer TS-WX130DA is exciting thanks to the Bass mode settings.

Its wired remote control enables phase settings and filter adjustments without much hassle. Needless to say, there’s not a better performer within this price range.

Sound Ordnance B-8PTD

Size: 9-1/8″W x 3-1/8″H x 13-5/8″D
Power: Peak: 250 watts RMS: 125 watts
Woofer Size: 8”
Frequency Response: 40-200 Hz

Even on a budget, we still want quality sound in our cabins. In the case of under-seat sub-woofers, you cannot go wrong with the B-8PTD.

The B-8PTD’s most decorative feature is its ABS enclosure; a rock-solid body that can take a tremendous amount of bashing over the years. The enclosure houses its aluminum cone which comes with quite a reputation.

Thanks to its cone, this sub is easily able to produce tight clean bass, a quality that most audiophiles search relentlessly for. On top of that, it also comes furnished with a class D amplifier that revs up the bass out-turn even further.

The B-8PTD has both preamp and speaker-level inputs. Its bass boost control lets its user tune the sound to suit the environment. Its auto turn-on switch and easy-to-understand controls make its navigation a piece of cake even for amateurs.

Last but not least, it includes a wired remote control; you can alter its settings without moving an inch.

Size: 13” x 2.5” x 11”
Power: Peak: 200 watts RMS: 120 watts

Frequency Response: 50-150 Hz

If you need a powerful sub on a budget that is also space-efficient, consider this Blaupunkt subwoofer. The sub boasts the 120W RMS output with its 10” cone. Despite these heavy specs, this sub is just 2.5” tall, allowing you to easily tuck it under the driver, passenger, or backseat.

Like the NVX sub, this one also features an aluminum die-cast heat sink so that it can continue to blast reverberating boost from the congested under-seat space without getting overheated.

Blaupunkt compact hideaway sub’s frequency response is perfect for producing the upper and mid-bass. This super slim subwoofer also works with both speaker and RCA-level inputs.


JBL BassPro Nano

Size: 10” x 3” x 8”
Power: Peak: 200 watts RMS: 100 watts
Woofer Size: 6×8”
Frequency Response: 30-150 Hz

Not all compact subs are made equal and therefore not all of them are suitable for every type of under-seat installation. If you think that a typical compact sub won’t fit under your car seat, consider this Nano subwoofer by JBL. This sub is just 10” long and 8” wide and can fit under the seats of any car model.

Despite having a “Nano” footprint, this JBL subwoofer doesn’t compromise on quality. Its 100W RMS amp with a 6” woofer produces a thumping sound as good as any large-sized subwoofer and speaker system.

Moreover, you get all the features in this Nano sub that are part of a full-size subwoofer. It works with both speaker and RCA inputs. Then, a wired remote control knob also comes with the sub that ensures hassle-free base control. The JBL Nano sub also features a built-in wire harness for simplified installation.

Size: 13.5″x2.8″x 9.8″
Power: Peak: 150 watts RMS: 75 watts
Woofer Size: 8”
Frequency Response: 45-150 Hz

We are rounding off our list with a Focal underseat sub that also has a profile more or less the same as the Sony XS-AW8.

It also features a Class-D amplifier with an 8” woofer cone with an RMS rating of 75 watts. They are perfect specs for producing moderate bass that reverberates but doesn’t deafen.

Focus IBUS20 also comes with low and high-level inputs, making it a versatile sub-option. You also get a remote control (wired) with the amp so that you can do the full installation in one go.

We also like its nonslip feet that cover all four corners and let you set it up under the seat without needing any mounting.

Really compact option

Infinity Basslink Mini

Size: 11.43″ x 3″ x 8.31″
Power: Peak: 200 watts RMS: 100 watts
Woofer Size: 6×8”
Frequency Response: 50-150 Hz

This Infinity subwoofer is another great option for cars where there isn’t enough trunk space. The compact profile of Infinity Basslink can fit under most car seats. Its all-die-cast aluminum enclosure design is worth mentioning for two reasons.

Firstly, it helps minimize the overall footprint of the sub. Secondly, it also cancels out the rattling regular under-seat subs can experience in a moving car. Its amp with 100W RMS power produces a good punch of high and mid-bass through its 6×8” woofer.

The high-pass filters and limiters also enhance the performance of this compact Infinity sub. The subwoofer also comes with a bass volume remote control to provide easy bass regulation from the driver’s seat.

We loved the Kicker for the phenomenal price to performance ratio it comes with the added convenience of ultra compactness.

Important aspects of picking under seat subwoofers

Bring your car stereo system to the next level by adding the 8″ subs, 10″ subs, 15″ subs.

The under seat subwoofers are an extremely innovative way of scaling down the classic, beloved, box-type subwoofer and the low-end frequency it produces. A cost-effective and convenient way of being able to enjoy previously unexplored depths to your music.

One of the most important considerations to bear in mind before buying a subwoofer is the total power output of the device, in watts. The diameter of the speaker housed inside the woofer is another basic consideration that defines the character of the product you select.

The resolution of the frequencies of the sound in your music is better when the diameter of the speaker is large. Couple this with a powerful amplifier and you can brace yourself for some high-quality music.

Almost all of under seat woofer systems come with a remote or a wired controller for convenient operation so that aspect is fairly covered irrespective of the model you choose.

Even though they cost more, underseat subwoofers that have a built-in amplifier, are about as comprehensive of a package as you can buy, so having ample power onboard is an important consideration.

Finding the right balance between onboard features, and power and ensuring that the speakers are as big as possible for a great price should ideally be your quest when you are out shopping for the best under seat subwoofer.
