3. Kicker 11HS8 Hideaway – Best for Easy Installation

Another reason I like this model is that, unlike a lot of subwoofers that strive to be small and lightweight, the PWE-S8 doesn’t compromise on build quality. It has a rugged aluminum enclosure that can withstand any road condition.

Alright, buckle up! Because I’ve got something unique to share with you now. I recently tried the Pyle 10″ Car Audio Speaker Subwoofer, and trust me, once you hear what this device can do, you’ll be itching to get your hands on one.
Pros
- An impressive power output of 1000 watts and 500 watts RMS
- Durable rubber construction
- Clear and crisp sound with reduced distortion
- Easy installation
- Highly affordable
Cons
- Handles low-frequency sounds better than mid and high-frequency ranges.
- The dual voice coil design of this subwoofer might introduce wiring complexities.
- No adjustable crossover frequencies or phase control.
First things first, let’s talk about power. This subwoofer is an absolute beast, boasting a mind-blowing maximum power output of 1000 watts! That’s right, 1000 watts of pure sonic goodness. When I cranked up the volume, my entire car shook with bass you could feel in your bones. It’s an immersive experience that makes every drive feel like a concert on wheels.
But power isn’t the only thing this under-seat subwoofer brings to the table. Pyle built this one to last. The non-fatiguing rubber suspension, specially designed rubber magnet boot, and non-press cone ensure durability, even during those intense bass-heavy sessions. They’ve gone the extra mile to guarantee this subwoofer can handle anything. Not to mention the specially treated foam surround and bumped and vented motor construction that keeps everything running smoothly even during extended use.
How about sound quality?
This subwoofer’s dual 4-ohm impedance is a real game-changer, compensating for the undersized wire commonly found in many modern cars. This reduces distortion and ensures a crisp and clear sound highlighting every detail in your music. The 2-inch 4-layer dual voice coil and 50 oz magnet structure significantly enhance its performance, allowing it to handle higher operating temperatures.
Installation was a breeze with the Pyle subwoofer. It follows the standard size for most vehicle stereo systems, so if you’re replacing worn-out or blown speakers, you’ll have no trouble fitting it in. The 4.7″ mounting depth and 10″ overall diameter balance size and power, making it an ideal choice for anyone upgrading their audio system.
Now, let’s talk about price. You might think a subwoofer of this caliber would break the bank, but hold on to your seat because it won’t. The Pyle 10″ Car Subwoofer comes at an incredibly affordable price. You’ll be getting high-quality, bone-shaking bass without draining your wallet.
7. Cerwin-Vega Mobile VPAS10 – Best Overall
- Power Handling: Peak: 550 watts RMS: 200 watts
- PWM MOSFET Power Supply/Thermal Protection Circuit Remote Subwoofer Control Included RCA and High-Level Inputs
Another great, power-forward subwoofer is the Cerwin-Vega Mobile VPAS10. This subwoofer earns our distinction for best overall because it exceeds expectations in all qualities and categories that make up an excellent under seat subwoofer.
Pros
- Powerful bass with high-watt amplifier
- Incredibly compact
- Extremely easy to install
- Great value for price
Cons
- Must be tuned to accommodate different musical styles
- Range only goes as low as 35Hz
Of all the models on this list, the VPAS10 is arguably the most compact at only 2.6 inches thick, making it small enough to fit underneath even the smallest seats in the sleekest sports cars. It is also made from a durable aluminum casing, so even though it is pretty thin, it can still hold up against any bumps you might encounter on the road.
As for the audio quality, the VPAS10 is challenging to beat. With a 10-inch woofer and a 450-watt built-in amplifier, this model produces some of the best depth and punchiest sound we’ve seen, so you’ll always feel immersed in your music.
This under-seat subwoofer has a bass boost of 0-12dB, a subsonic filter of 35Hz, and a low pass filter speaker level of 75-150Hz.
And if that wasn’t enough, the VPAS10 also excels at all the little things. It includes a thermal protection circuit so you can jam out for hours on end without worrying. Its auto-turn-on mechanism incorporates a unique, soft-delay feature to help prevent ear shock, so you’ll never be surprised when the bass suddenly drops as you turn on your car’s audio system. And my personal favorite, the VPAS10, is installed via heavy-duty Velcro strips.
If you’re anything like me, mounting and god-forbid, unmounting a piece of electronic equipment is the hardest part of setting it up. The VPAS10 is specifically designed so that even people like us, who struggle to remember what a Phillips head screwdriver looks like, can easily install it.
Best Under-seat Subwoofer for Car Buying Guide
Should I Get an Under seat Subwoofer or a Box-style Subwoofer?
When most people think about transforming a car’s audio system, they immediately picture large, box-style subwoofers that get mounted in the car’s trunk and produce the kind of mind-altering bass that can cause a vehicle to bounce up and down.
The downside to these subwoofers is that they are cumbersome and often quite costly. An under-seat subwoofer is more than enough for the average motorist who simply wants to upgrade their vehicle’s built-in sound system. As the title suggests, these models can fit underneath the passenger or back seat and thus don’t take up any extra space. They’re also significantly lighter, cheaper, and easier to install. Many under seat subwoofers also come with built-in amps, whereas almost all box-style woofers require a separate amp.
That said, a full-sized box-style subwoofer’s sound quality is unparalleled. If you imagine yourself cruising through the neighborhood, playing your music on full blast, and feeling the bass resonate throughout your body, then a box-style model is your best bet.
When choosing between the two styles, consider how much space you have, how much you’re willing to spend, and how important it is to have the best sound quality. If you have a particularly compact car or are on a tight budget, choosing an under-seat subwoofer over a box style has already been made for you.
Is Under the Seat Subwoofer Any Good?
The short answer is yes. Under-seat subwoofers may not have the same raw power that comes from a 15 to 18-inch driver disc, but they are mighty and can make a noticeable difference in your listening experience.
Under-seat subwoofers boast significant frequency ranges with levels as low as 20Hz. This means that they are responsive to even the lowest pitches. They also come with woofers as large as 12 inches, enabling them to achieve louder, deeper sounds. For context, box-style subwoofers begin at around 12-13 inches and usually have 20-200 Hz frequency ranges.
The area where this type of subwoofer typically falls behind is power. All drivers come with peak power-handling ratings and root mean square power ratings that indicate how loud the speaker can play for short bursts or continuous periods. Full-sized subwoofers often have capabilities greater than 1,000 watts, while under-seat subwoofers max out at 400-800 watts for short bursts, with much lower capacities from long listening periods.
While this may seem like a drawback, it’s essential to consider audio power in a vehicle environment. One thousand watts, projected into close quarters, is roughly the equivalent of standing directly beside a military jet aircraft as it takes off. Chances are, you won’t need or want this kind of power when you’re driving. An excellent under-seat subwoofer likely offers more than enough wattage for all your listening needs.
Choosing the Best Under Seat Subwoofer for Your Car
The under-seat subwoofers in this list are some of the best models on the market. They all combine solid construction and build quality with a superior audio experience.
When choosing which option is best for you, first consider the type of vehicle you have. If you have a sports car, you’ll want to consider a compact model. You’ll have more options if you drive an SUV or small truck.
After that, it’s all about deciding which design considerations appeal to you most. Regardless of your choice, an under seat subwoofer will transform your car listening experience.
