IN THIS GUIDE


What’s the best powered subwoofer for your car?

Here’s the deal:

You’re looking for a subwoofer that’s easy to install, budget-friendly, and will rock the bass, however you want, for your choice of music.

You just want it to perform the way you want.

Simple.

But what do you need to know about a subwoofer so you can decide if it’s going to give you the sound you want BEFORE you sink a whole bunch of money?

You might be wondering?

As you scroll down this article, keep these points in mind:

  1. Think about your budget. Subs run anywhere from about $100 upwards
  2. Where do you want to put the sub? Under a seat? In the spare tire? On the floor?
  3. What kind of music do you listen to most of the time? This will influence the type of enclosure that will work best for your choice in music

And did you know?

  • A lower Hertz (Hz) rating will typically produce more bass
  • The enclosure makes a difference. Ported, great for hip-hop or rock. Sealed, nice low bass and bandbox will produce hardest at low frequencies. Read more about enclosures.
  • Cone size matters. Yup, you read that right. 10″, 12″ or 8″ for different results.
  • And what about dB? Does it matter? Look for a rating of 3 dB or more for more power and sound.

We’ve done the research to make it easier for you to decide which powered subwoofer will work best for your choice in music

What Is A Powered Subwoofer And Why Do You Need It?

A powered subwoofer has a self-contained speaker and amplifier that are typically matched for optimal sound performance. The amplifier provides a source of power which eliminates the need for an external power source, just a sound source.

Quite often, factory-installed stereo systems don’t have great sound or much bass. By adding a subwoofer,  you’ll get more bass in your music which can improve the sound all around.


Alternatives To Powered Subwoofers

The alternative to a powered subwoofer is a passive subwoofer. A passive subwoofer doesn’t have an internal power source which means you’ll require an external power source such as an amplifier. 

Quite often, installing a passive subwoofer is more difficult and more expensive than a powered subwoofer because of the need to buy an amplifier and do the installation of both the sub and amp. 


5 Benefits Of Using Powered Subwoofers

  1. Easy to install because you don’t need to do extra electrical work like you do when installing a passive subwoofer
  2. Wide price range from under $100 to $700+ giving most people great options
  3. Performance optimized due to the pairing of an amp and sub that are designed and engineered to work well with each other
  4. Most often a compact design which makes it easy to find an installation location such as under a seat

13 Things To Look For In A Powered Subwoofer

  1. What kind of music do you play? A bigger speaker will give you more output and fuller frequency response. 
  2. Enclosure Type The type of enclosure also plays a big part in how your music sounds. Here are 3 enclosure types and how they influence performance: (1) Ported enclosures are great if you listen to a lot of rock, hip-hop, techno, because it will produce the low bass that gives that deep, loud boom to these types of music (2) Sealed box enclosures add some low bass that is particularly suited for classical and jazz music. (3) Bandpass box booms hardest at low frequencies, perfect for music with strong, focused bass hits. 
  3. What’s your budget? Most quality powered subwoofers are going to start at $100 and go up from there. You can find a decent one for the low $100s, but just know that typically, the larger subs will cost more but will also have the ability to provide more power and sound. How much you pay will depend on how much sound and what kind of performance you’re looking for
  4. How much space do you have? If you’re short on space, look for either an under seat powered subwoofer or a powered sub that is designed to fit in your spare tire. The Rockville RockGhost or the Recoil SL1708 great options. If you have plenty of space and are happy to give up the real estate in your trunk, go for a larger system like the Skar Audio Dual 12″
  5. Tuning and Ease of Use – A sub needs to be easy to install, easy to use, and simple to tune with the ability to optimize performance. Look for a powered subwoofer that has bass boost EQ and filters. Many have a remote control which simplifies tuning on the fly
  6. Power handling Max power will give you a good indication of how loud the subwoofer is. Generally, the higher the power, the louder the sound. The amplifier will also need to be powerful to support the subwoofer. This is where a powered subwoofer stands out because the all-in-one subs and amps are typically configured to perform well together
  7. Cone Size – All subwoofers have a cone and the size of the cone will impact the type of bass you’ll get. If you want deep bass, go with a 10” or 12”. If you prefer punchier bass, try an 8”. One thing to remember is that the larger the cone, the more expensive the sub and the larger it will be, requiring more real estate
  8. Sensitivity — Sensitivity tells you how much volume you’ll get from a speaker with a given amount of power. A sub that has a higher sensitivity rating requires less power to produce the same amount of sound as a model with a lower sensitivity rating. Also referred to as efficiency (measured as SPL — sound pressure level), this specification is quoted in decibels (dB). The higher the number, the more efficient the subwoofer is at turning amplifier power into sound, and the louder it plays. A subwoofer rated 3 dB more than another will require only half the power to produce the same output.
  9. Frequency range — A speaker’s frequency response is measured in Hertz (Hz) and tells you how accurately it converts the frequencies of an input signal. It’s common to see specs such as 60 Hz to 18 kHz. This means that it can convert frequencies in that range with some accuracy. Other factors, such as the enclosure or cone size also impact sound output. 
  10. Number of voice coils — Typical subwoofers have a single voice coil but a dual voice coil (DVC) subwoofer uses two separate voice coils, each with its own connections, mounted on one cylinder, connected to a common cone. Performance is the same for both single or dual voice coils but the dual offers more flexibility in wiring sound systems.
  11. Impedance — Many subwoofers are rated at 4 ohms impedance, but 2-ohm, 8-ohm, and dual voice coil subwoofers are more common. When you’ve chosen a passive subwoofer, look for an amplifier that will perform best when matched with your sub in terms of power rating and impedance. A powered subwoofer, such as the subs on our list, will have an amplifier that has been correctly sized and designed for optimum performance with the sub, the cone, and the enclosure.

FAQs for the Best Powered Subwoofers

Are 2 subs louder than 1 sub?

Whether 2 subs are louder than 1 sub depends on various factors so there isn’t a straightforward answer. You need to consider the power, the enclosure type and size, cone size, and the size of the space you’re installing (small car vs large truck). Typically, two subs will sound a little cleaner and punch harder.

How do I get more bass out of my subwoofer?

Assuming that you have a powered subwoofer, you can improve the bass performance by: 

1. Setting the speaker level to remove crackling, hissing and any other undesired sound
2. Removing the distortion – set the amp gain to low, play some music and turn up your receiver’s volume until you hear the distortion. Note where the distortion started because this is the loudest volume setting
3. Flattening the signal
4. Adjusting the subwoofer gain and low-pass filter until you don’t hear any mid and high-frequency sounds
