The Best Car Subwoofers Reviews – Buying Guide

Best Car Subwoofers

“You know you can get a lot better sound in your car, right?”

My wife’s brother, Nick, said that to me last Thanksgiving. Nick, 19, is 15 years younger than me and has been obsessed with car stereos for as long as I’ve known him. The two of us were on our way to pick up some last minute items from the grocery store. We’d been listening to music for a while when he suddenly said that my car stereo wasn’t nearly as good as it could be.

Turns out, Nick knows a ton about car stereos, especially car subwoofers. Over the next few months, I asked him many, many questions while I considered which subwoofer would best suit my needs for my car and what are the best  car subwoofers on the market.

High quality with a low price tag. Perfect for anyone new to car subwoofers

My brother-in-law is a total audiophile who has no problem dropping a lot of money on stereo components. But many subwoofer newbies are understandably reluctant to spend big bucks on their first subwoofer. The MTX TNE212D 1 is a high-performing subwoofer with an affordable price tag designed for even a modest budget.

  • View On Amazon.com

With over 40 years of experience, MTX has a sterling reputation for developing speakers and stereo components. The TNE212D is an all-in-one subwoofer kit containing a dual 12” sealed enclosure with a single terminal cup.

The ported enclosure allows for a big, open sound. A great choice for people who enjoy incredibly bass-heavy music like dance and rap.

Nick says, “Looking for a subwoofer which will rock the block? This pair of ported subwoofers produces amazingly loud, low tones.I think this is one of the best dual enclosed subwoofers.”

Pros

  • Dual 12” ported subwoofer with peak 1200 watts
  • Remote controlled bass and level inputs
  • Complete all-in-one package with easy setup

Cons

  • Amp can potentially blow out at high volumes
  • Ported enclosure has intentional distortion

High performance from a manufacturer you can trust

Kenwood is a trusted name in audio and their KFC-W3016PS subwoofer shows why. Peak power output is 2,000 watts with RMS power of 400 watts. An oversized diaphragm produces anoversized sound which fills the car (and, at high enough volume, also the surrounding area).

Durability and quality combine. The subwoofer’s heavy-duty polypropylene coneis reinforced with tough rubber. Also includes a single 4-ohm voice coil. Works well with a 500-watt single output amp.

  • View On Amazon.com

Nick says, “In my opinion, the Kenwood KFC-W3016PS is one of the best 12 inch subwoofers. Lots to like with this one.”

Pros

  • Trusted manufacturer
  • Peak power output of 2,000 watts
  • Durable, heavy-duty polypropylene cone

Cons

  • Does not include amp
  • Bass boosting can blow speaker

Solid construction helps prevent blowouts and other malfunctions

Don’t judge a subwoofer on its size alone. Big sounds can come in small packages. Skar Audio’s VVX-8v3 is an eight-inch subwoofer, but the unique design results in a sound far beyond its dimensions. A competition-grade paper cone with rubber butyl helps enhance low-end frequencies.

Long, loud play time is no problem thanks to the triple stack motor assembly and two-inch high temp copper voice coil. Risk of overheating, burnout and blown speakers are minimal. Works well when you want to listen to a lot of music during a long drive or even a road trip.

  • View On Amazon.com

Note this is just the subwoofer. You’ll need to purchase an amp and enclosure separately. Use a sealed enclosure if you want a full range of low tones. Ported will work better if you want a booming sound. 

One benefit of the small size of the speaker is that the enclosure can be small, too. This is a great choice if you have limited space in your trunk, cargo bed or backseat.

Nick Says “I’m always going to recommend 10 or 12-inch speakers. But if your vehicle has limited space, and you want subwoofers on the small side, Skar Audio’s VVX-8v3 is what I’d recommend.”

Pros

  • Compact eight-inch size perfect for small vehicles
  • Triple stack motor assembly handles long playtimes
  • Wide range of low frequencies

Cons

  • Small size runs risk of damage in shipping
  • Enclosures for eight-inch speaker can be hard to find

A complete kit which is small in size but big in sound

Interested in a smaller subwoofer but don’t want to hunt down individual components? This eight-inch subwoofer kit from Alpine Electronics includes a built-in amplifier and aluminum enclosure. The entire system is 13.5 inches long by nine inches wide and three inches deep. Fits easily into a trunk or other out-of-the-way location in your vehicle.

  • View On Amazon.com

The enclosure is made from die-cast aluminum, which offers a high degree of durability and will last for many years. The included amplifier produces 120 watts of power. This is a quad-coil subwoofer with a frequency response between 32Hz and 150Hz.

Connecting the unit to your sound system is easy with the Auto-Sensing Speaker Level Inputs located on the side panel. Sound setup and customization options on the panel include Phase, Gain, LP Crossover and Remote Sub Level.

Nick says, “Alpine subwoofers are known for their high quality and PWE-S8 is one of the best 8 inch subwoofers around. Small, durable and powerful.”

Pros

  • Strong die-cast aluminum enclosure
  • Quad coil with 120 watts of power
  • Compact design with a small footprint

Cons

  • Installation can be complicated
  • Eight-inch subwoofer

A big 15” for large vehicles looking to create big sound

Want to go big? Kicker’s 15-inch car subwoofer is definitely ready to rock. Includes both the subwoofer and a single-vented sub box.

The box has 2.7 cubic feet of airspace. Vented designhelps increase sound output while also helping to prevent overheating. Total size of theenclosure is 21 inches by 16.25 inches by 18 inches. Made from MDF wood, it’s strong enough to withstand bumps and bangs. The enclosure has a mounting depth of 7 7/17 inches. 

  • View On Amazon.com

Inside the enclosure is the Kicker 43C154 subwoofer with 600 watts of max wattage and 300 RMS power. This is a single four-ohm subwoofer with a 45-ounce magnet structure. Unique ribbed surround helps prevent blowout even at sustained high volumes.

Nick says, “Not many people really need a subwoofer this big. But if you’re interested in having the loudest car subwoofers on the block, this model from Kicker is arguably the best 15 inch subwoofer to claim that title.”

Pros

  • Maximum volume
  • Ribbed surround helps prevent blowout
  • Strong enclosure

Cons

The unique IMPP Composite Cone is rigid and powerful. Newly redesigned, the subwoofer has a single piece cone and drive cone. Delivers powerful sound with minimal risk of cone failure at high-pressure levels.

  • View On Amazon.com

Nick says, “Pioneer uses a lot of one-of-a-kind design elements but it really pays off with a subwoofer which is strong but unlikely to blow out.”

Pros

  • High quality construction helps prevent blowouts
  • Trusted manufacturer
  • Single piece vibration minimizes distortion

Cons

  • Hard plastic in front can rattle

Buyer’s Guide

I’ve always gotten along well with my brother-in-law. But we didn’t have many common interests. So imagine my surprise when we started to bond over car stereos and subwoofers.

Finding impartial information online can be a challenge. Many buyer guides are thinly disguised advertisements for specific products. That’s just not impartial enough for me. So, with my brother-in-law’s help, I set out to create a 100% honest buyer’s guide for selecting the best car subwoofer for your needs.

When my brother-in-law first told me I should consider adding a sub-woofer to my ride, my first thought was “no way.” Subwoofers just didn’t seem like my thing. I figured they were better suited for people who mainly listened to very loud, very bass-heavy music.

But Nick explained that subwoofers are far more versatile than I imagined. Subwoofers add depthand richness to the sound far beyond what factory speakers are capable of. They can do far more than just bump the bass.

While Nick loves loud, bass-filled music (Wu-Tang Clan is one of his favorites), subwoofers actually enhance all types of music. When installed and setup correctly, bass won’t overpower the rest of the song.

“People who want to rattle windows with bass really aren’t doing it right,” said Nick. “When a subwoofer is properly setup, the sound inside the car will be full, but the bass won’t overpower everything else. I mean, I actually want to hear the vocals in a song, not just never-ending low tones.”

The Importance of In-Car Acoustics

The inside of your car is actually a pretty unique shape. While that might sound obvious, Nick explained how a car’s shape can have a drastic effect on acoustics. Nick described how even the best factory speakers aren’t able to create the ideal wavelengths within the relatively small space of a vehicle.

Low tones are the hardest frequency range for factory speakers to reproduce naturally. This is because low tones require the movement of a large amount of air. For instance, 20Hz requires a wavelength of 56 feet.

Car subwoofers fill your car with sound. They’re able to create low, midrange and high-range frequencies. Subwoofers are also designed to properly regulate the power provided.

Types of Subwoofers

Subwoofers can produce big sound. So the bigger a subwoofer is, the better, right? What are the best  car subwoofers ?According to Nick, that’s not always the case. Size doesn’t always directly correlate to sound quality.

Subwoofers range in diameter. The typical range is between eight and 15 inches. Larger subwoofers produce lower frequencies.

“If you really search, you can find subwoofers in basically any size,” said Nick. “But the most common types, and my personal preference, are either 10-inch or 12-inch subwoofers.”

He explained 10 and 12-inch subwoofers have the perfect balance between sound and power use. They can reach 20Hz, which is the lowest tone humans can hear.

Rattling windows wasn’t my goal. But Nick still recommended I focus on subwoofers which can reach 20Hz. Subwoofers are designed for low frequencies, so you might as well get one with the lowest possible range.

He then explained I didn’t have to pay as much attention to the high-frequency range of the subwoofer. The standard car stereos can handle those frequencies just fine. In fact, car stereos tend to produce high frequencies better than subwoofers. The position of the driver relative to the factory speakers usually meansyou’ll hear vocals and higher tones clearly.

The Importance of Subwoofer Power

I was so focused on the audio aspect of subwoofers I never really considered the power issues. Nick explained how subwoofers connect to your car’s power supply. Because they move such a large amount of air, subwoofers require a fairly substantial amount of power – much more than the power required to operate your car stereo speakers.

Nick explained why I need to consider the sensitivity of the subwoofer. Sensitivity is the measurement of the subwoofer’s efficiency. Sensitivity is rated by the decibel output at one meter away from the subwoofer with a power output of one watt. For every three decibel increase in sound sensitivity, the power output is decreased by half. For instance, 90dB sensitivity needs 100 watts but a 96dB subwoofer only needs 25 watts.

Nick then went on explain the importance of continuous power handling. That’s the amount of time a subwoofer can play without distortion or damage. Typically, the biggest power demands will occur during the crescendo of a song. A high power rating prevents the speaker from blowing out at high volumes.

“Most subwoofers are perfectly fine for most songs,” he said. “Problems can happen with long, sustained, low tones. You want to make sure the subwoofer can handle an occasional decibel spike.”

Nick then went on to explain that I didn’t listen to music which was “weird” enough to run much of a risk. Certain EDM and rap songs are more prone to a volume spike, but it’s not an issue with most mainstream music. 

Enclosure Installation and Placement

The enclosure is the box which contains the subwoofer speakers. Most vehicles don’t have a pre-mount installed to hold a subwoofer securely. Nick explained that there are two options. You can buy a complete subwoofer kit which includes an enclosure and mounting brackets.

The other option is to build your own subwoofer enclosure. Most experts recommend pressed fiberboard. Light thickness will work okay, Nick explained, but ideally you want fiberboard with a medium thickness or better. He recommends fiberboard with a thickness of 5/8th of an inch. That helps contain the low frequencies while also providing plenty of protection from accidental damage.

“I’ve made a few enclosures and the thickness of the wood really matters,” said Nick. “Really thin enclosures help the sound spread through the car. But the problem is thin fiberboard can easily be punctured. That can totally mess up your speakers.”

“On the other hand, if you go too thick, the sound will be muffled. Fiberboard which is 5/8ths of an inch thick is really the perfect balance for both sound and security. If Goldilocks was building a subwoofer enclosure, that’s what she’d use.”

The Two Types of Subwoofer Enclosures

Enclosures can be either sealed or ported. Whether you’re building your enclosure or buying one, the type can make a big difference in the sound quality. Nick helped me understand the difference between the two types.

Sealed boxes have the clearest bass lines and most accurate low-end bass. If you want distortion to be minimal, or even non-existent, you’ll want a sealed enclosure. The interior air pressure is stabilized with the outside air when the subwoofer is in operation. Stabilized air causes minimal movement of the subwoofer, which results in a clearer sound. Sealed boxes take up less space but require more power.

Ported enclosures create a thicker, heavier sound. The port is a hole in the enclosure which lets the woofer move freely. “The woofer basically punches the outside air,” said Nick. He then explained the sound from a ported enclosure purposefully has a distorted, almost abrasive quality. Ported enclosures create a bigger sound and require less power than a sealed enclosure.

“If you want the best subwoofer for deepbass, get a ported enclosure,” said Nick. “If you listen to a wide variety of music, and aren’t as concerned about the deepest bass possible, a sealed box is probably better.”

Subwoofer Placement

Typically, you’ll want to put the subwoofer either in your backseat or trunk. Nick explained that both have advantages and disadvantages. Backseat placement really lets you feel the rush of air. For audio guys like Nick, this is pretty important. But a subwoofer in the backseat basically sacrifices all passenger seating.

At the same time, trunk placement muffles the sound. Personally, I don’t notice a difference but audiophiles like Nick certainly seem to. Trunk placement frees up seating, but you’ll end up with less trunk space. “That’s just the price you gotta pay forkick-butt car audio,” said Nick, laughing.

Help and Support

A one-year warranty is usually pretty standard. Some more expensive models will have longer warranties. Five years is typically the maximum. Nick recommended buying a subwoofer with at least a one-year warranty.

Who Makes the Best Car Subwoofers?

Even though I was new to the world of the car subwoofers, I already had a good idea. The best car subwoofers are made by brands you’ve heard of. Brands which have been around for a while. Rockford Fosgate, Alpine, Kenwood and other established brands are all pretty much a safe buy.

“Look, you’ve got to understand that there’s an enormous gulf between the good and bad in the world of subwoofers,” said Nick. “While people like me love to argue about the intricate differences between, says, Alpine and Kenwood, that’s really kind of missing the point.”

“No-name mystery subwoofers tend to flood the industry. Ever been approached by some guys in a van with a story about a ‘delivery error’ who are looking tosell some subwoofers at a deep discount? Yeah, that’s a total scam.”

Apparently a timeless one, because the type of people he described were all over town when I was in college, which was over 20 years ago.

“You want to purchase subwoofers in a store or online, and only from an established company. You always want at least a one year warranty for any speakers you buy.”

He then went on to make an important point I’d never considered.

“If you’re buying online, that warranty is especially important,” he said. “Subwoofers are pretty safe when they’re securely fit inside a wooden box in your trunk. But when they’re being shipped across the country, they’re actually pretty vulnerable. You want to make sure you can get a replacement if anything arrives damaged.”

Conclusion

I ended up with a Rockford Fosgate 12” Punch Series with a sealed enclosure for my car. But then I went with the MTX Audio Terminator Series TNE212D for my wife’s car. She loved the sound system in my car so much she wanted a subwoofer on her own, but didn’t want us to spend a lot of money.

All in all, I’m super happy I decided to install a subwoofer. The improvement to the overall sound quality is simply tremendous. I had no idea what I’d been missing. 

I’d also like to take a quick moment to thank my brother-in-law Nick. Thanks Nick! Couldn’t have done it without you!

Both Nick and I hope our guide to the best car subwoofers has been useful and informative. Whether you want fuller sound inside your car or want a bass boost to rattle every window in time, there’s a subwoofer out there which is bound to be perfect.
