It’s also quite easy to configure the device to your liking by customizing how you set up the subwoofer and connecting to third-party speakers.

Alpine is another well know brand renowned for high-quality sound with a pretty big reputation; so it’s no surprise that the Alpine PWE-S8 is one of the best under seat subwoofers available.

Its compact design is powered by an 8-inch subwoofer with a 120W built-in amp with a cast aluminum enclosure.

It’s a pretty small compact device; maybe not as thin as other models mentioned in this roundup review, but still fairly compact (13.5” x 9” x 3”), which will under the seat of any truck, car, or SUV with ease.

This makes it a good fit for anyone who doesn’t want to sacrifice any space but wants to have some high-quality bass to their sound system.

One thing I must mention is installing this device; it’s so important that this is done right.

If you don’t install this correctly; you will be so underwhelmed with the sound quality it produces; so try and make sure you take your time and follow the instructions; especially if you aren’t sure what you doing.

If you are unsure, the Alpine Tech Support is great and will be able to help you out.

The Alpine PWE-S8 connects to your vehicle’s sound system through the RCA or Auto-sensing Speaker Level inputs.

On the device itself, you can control the Phase, Gain, LP Crossover, and Remote Sub Level controls; there’s also a remote with an 8ft cable to control the gain.

Compared to the Pioneer TS-WX130DA and the Kenwood KSC-SW11 which both run at less than 75w RMS, the Alpine PWE-S8 runs 120w RMS with a 240 max limit and right now is pretty much the same price as the Pioneer.

The Alpine PWE-S8 is an excellent subwoofer for under seats that should definitely be considered.

Kenwood KSC-SW11 – Best Best Enclosed Subwoofer For Cars

The KSC-SW11 is one of my two Kenwood options that has made my list and is my best enclosed subwoofer for car recommendation.

The Kenwood KSC-SW11 is specifically designed to be compact and for vehicles that are short on space but want to add a little bass to their current or factory sound system.

Weighing just over 6 pounds and such a small frame (11 x 7.5 x 2.75 inches); it fits easily under the seat of your car or can be tucked away neatly in the trunk.

As this is a powered subwoofer, you won’t need to worry about connecting it to an external Amp to get this to work.

What you get is a 150W subwoofer that pushed out a lot more bass than you might expect.

Using the remote that’s included you can tune to sound to your liking by setting the HZ to avoid any distortion and also adjusting the volume to suit the type of music you are listening to.

This will need to be done manually of course as it doesn’t have the dynamic bass mode function that you get with the Pioneer TS-WX130DA which will intelligently enhance different frequencies from the music being played.

Like most Kenwood subwoofers, the KSC-SW11 is very easy to install. Simply, wire the subwoofer to your battery ground it, and then connect it to your head unit using RCA cables.

You will need to purchase the RCA cables separately as they are not included with this unit.

Overall, the Kenwood KSC-SW11 is an excellent device and is my best-enclosed subwoofer for car recommendation.

One I think I hate about doing these round-up reviews is that the one brand might have multiple options making my recommendations.

This post is no different.

However, they usually vary in price for your standard budget, mid-range and premium range options.

The Rockville SS8P is my best under seat subwoofer under $100 recommendation.

For less than $100, you are getting a good quality, power unit, and full amp install kit. Not bad for less than $100.

The Rockville SS8P is an all in one unit with an amp in a slim 2.8″ thick frame.

Since the amp is built-in, it makes the installation a breeze (once you can follow instructions at least).

An easy to install device was one of Rockville’s main goals when designing this under seat subwoofer.

Rockville wanted to ensure that their device could be easily connected to any vehicle factory or aftermarket system.

They also made the install easier again by placing all the inputs and outputs on one side of the subwoofer, keeping everything neat and tidy.

Like the Rockville RW8CA mentioned below in this post, the SS8P 400 also has the smart turn on that will automatically turn the amplifier on and off when it senses an audio signal.

The SS8P produces 400 watts of peak power and 100 watts RMS; which is quiet goo considering it costs less than $100.

If you are looking to add a little more kick to a factory vehicle sound system; the extra little bass this device produces makes it a great purchase, especially if you don’t want to blow your ears off and empty your wallet.

The Rockville SS8P 400 is without a doubt one of the best budget under-seat subwoofers that come as an all in one unit with an install kit included; all for less than $100.

Rockville RW8CA 8″ – Best Budget Under Seat Subwoofer

Rockville RW10CA 10" 800 Watt Slim Low Profile Active Powered Car Subwoofer Sub, Black
  • Rockville RW10CA 800 Watt 10" Slim Car Subwoofer.Waterproof : No
  • 800 Watts Peak / 200 Watts RMS. PWM MOSFET Power Supply.
  • Low Level RCA Input. High Level Inputs with Auto Turn-On Technology.
  • Adjustable Input Sensitivity. Soft Delayed Remote Turn-On.
  • Thermal Protection Circuit, Short Protection Circuit.

It’s no surprise why the Rockville RW10CA is one of the best under seat subwoofers you can buy online.

You don’t need to worry about any false promises from Rockville as this model has been approved by the Consumer Electronics Association.

So you can be rest assured, whatever Rockville is saying, you can be sure it’s true.

In fact, the Rockville RW10CA is one of the only slim under-seat subwoofers that are compliant with the Consumer Electronics Association (CEA).

Ok, that sounds great an all, but what are you getting if you pick up one of these?

With 600 watts of peak power and 150 watts RMS, the Rockville RW8CA packs plenty of power for such a slim device (2.7 Inches Thick).

For such a thin device, the level of bass is quite impressive; and it can be easily controlled using the remote control that included.

If you are buying this particular model; I would definitely consider buying the bundle with the amp and install kit.

It’s only a little bit extra but makes the install easier and more straight forward.

The device is very easy to install and what’s great is you don’t need a remote wire from your receiver to trigger the unit on and off.

Why is this useful?

Well, if you aren’t too familiar with installing the subwoofers; it means when you turn off your music signal, the amp that’s built into this system will automatically turn itself off.

The Rockville RW8CA is excellent value considering the quality and bass you get compared to other setups without spending a fortune.

I know these are generally hidden under the seat or in the back of the car, but I like the design of this model.

The blue is really cool looking and will suit the eye of someone who doesn’t want the same plain boring black.

The JBL BassPro is a tidy 8″ under seat subwoofer that packs a punch.

In fact, according to JBL, it’s designed to “provide low distortion and great bass performance in an ABS enclosure with a remarkably compact footprint.”

If you are looking for a small, power under subwoofer that enhances your vehicle’s sound system; this could be the one for you.

The Crossover control and flexible EQ adjustments let you tune the upper and mid base to suit the rest of your car speakers for a smooth transition.

One thing that I must mention is the efficiency of the JBL BassPro.

It requires very little current from your car’s electrics to run and also keep cool.

You won’t hear the bass from two blocks away, but you aren’t supposed to with this subwoofer.

The goal here to have a high-quality subwoofer that fits under your seat that gives anyone’s sound system.

This particular model is best suited for cars, rather than trucks I feel.

Its small design fits perfectly under the seat of many cars rather than deep in the back of a truck. One other thing that might throw some people off is the price.

It’s almost double the price of the Rockville RW8CA and its one of the best selling models currently available on Amazon.

Kenwood KSC-PSW8 8″ Under Seat Powered Subwoofer

Kenwood KSC-PSW8 250W Max (150W RMS) Single 8" Under Seat Powered Subwoofer Enclosure W/Remote Control
  • Class D amplifier
  • 150 watts RMS power (250 watts maximum)
  • Frequency response: 35-150 Hz
  • Sensitivity: 81 dB

The Kenwood KSC-PSW8 under seat subwoofer is designed to produce high-quality bass from a small and compact device that fits nicely under your seat.

It’s not the most powerful under seat subwoofer that some of the others mentioned in this post, but it doesn’t need to be.

The Kenwood KSC-PSW8 produces 150 watts of RMS power and 250 watts at its max.

You can control the bass from the driver’s seat using the wired remote that’s provided.

However, what you can control with the remote is limited compared to some other subwoofers for under car seats that we mentioned.

Using the remote, you can control the crossover, gain, and phase.

For example, the JBL BassPro also lets you control the upper and mid-level bass.

It’s not a major thing; but when you are looking for one of the best under seat subwoofers, and its costing over $200; you would expect a little more control ability.

A wiring harness and mounting brackets are also included to install this relatively easy.

This is a great subwoofer for under your car seat.

It sounds great, looks great, it’s easy to install, but I wish there was a little more control options to allow you to get the perfect sound transition between the subwoofer and vehicle system.

This might be more of an issue for the proper sound junkies who have that ear for every decibel.


Are Under Seat Subs Any Good?

Yes, the main purpose behind under-seat subwoofers is to improve your current sound system without sacrificing any space. Despite their small size, some of the best under seat subwoofers can produce a high level of bass which can greatly improve your factory or third party sound system.

Can You Put A Subwoofer Under A Seat?

Yes, subwoofers that are small and compact can be put under your car seat. Subwoofer manufactures have realized this demand has created and designed under-seat subwoofers with this need in mind.

How Do You Install Under Seat Subwoofers?

If you purchase an under-seat subwoofer it will come with step by step instructions on how to install and set up the device.

It basically consists of wiring the subwoofer to your battery, grounding it, and then connecting it to your head unit using RCA cables.

There’s plenty of YouTube videos available online that should be able to help out with this.
