Best Car Subwoofer

Subwoofers are specially-designed speakers built to handle extra-low frequencies that make up the ’bass' in music. While not strictly necessary for basic bass reproduction, a good subwoofer goes a long way towards adding that extra low-end punch which is lacking in most factory audio systems.

Subwoofers are normally installed in 'sealed' or 'ported' enclosures, with each enclosure type offering distinctive playback characteristics. Sealed enclosures generally deliver tight, accurate bass hits while ported enclosures specialize in loudness and low frequency response. If you’d like to learn more about the different considerations that go into picking a new car subwoofer, check out our buyer’s guide below.

Despite the heavy-duty design, the MM1240 can handle up to 425 watts RMS, and will survive in just about any condition encountered in a daily driver.

JL Audio 12W7AE-3 12" 3-Ohm Component Subwoofer

For the 10th anniversary of the W7 subwoofer, JL Audio marked this important milestone by discontinuing the W7 lineup. In place of the original W7 is the W7AE, which is identical to the 'regular' W7 with the exception of a few cosmetic modifications. The outlandish performance remains - this massive subwoofer is best suited for hardcore bass junkies or for competition use. The 12W7AE is 'overbuilt' for a good reason - this subwoofer boasts over an inch of excursion, combined with more cone surface area than any comparable 12-inch subwoofer. Bass output is tremendous - when placed in a proper enclosure, even a single 12W7AE can drown out most multi-subwoofer setups that competitors offer. All W7AE models require substantial power for best performance - in this case, JL Audio recommends anywhere from 400-1000W RMS.

Unless you're planning on attending SPL competitions, the JL Audio 12W3v3-4 is one of the best subwoofers for everyday use. The W3v3 series strikes the perfect balance between bass output and sound quality - the 12W3v3-4 is capable of vibrating windows and mirrors while delivering spot-on low frequency reproduction. The W3v3 subwoofers don't require monster amplifiers for adequate performance - anywhere from 150-500W RMS is enough to extract substantial bass output.

Don't confuse this subwoofer for the P3D412 - the '-' indicates an entirely new model. The P3D4-12 is a 12-inch, 4-ohm subwoofer with dual voice coils, and sits at the top of Rockford Fosgate's midrange 'Punch' lineup.

Focal Access 30 A1 DB Subwoofer

Focal Access 30 A1 DB Subwoofer

Focal has built up its reputation for top-end audio products, no matter the price tag associated with any particular model. The Access 30 A1 DB may represent an 'entry-level' pick from the Focal subwoofer lineup, but this subwoofer is anything but basic. For starters, the cone material is typical Focal: a woven glass-fiber base is paired with a butyl rubber surround to ensure strength and fidelity, even at higher volumes. The basket is specifically tuned to resist unwanted resonance, and the dual 4-ohm voice coils provide added flexibility with wiring.

Buyer's Guide


Car Subwoofer Buyer's Guide

Whether in a vehicle or otherwise, subwoofers are dedicated to handling low frequencies. This leaves the rest to the other speakers, allowing each component to handle what it is best at. Regardless of the type of music you like or the volumes at which you listen to it, a good subwoofer can improve the sound quality and overall listening experience. We’ve put together this car subwoofer buyer’s guide to help clarify the process of choosing the right one for your needs.

Subwoofer Types

Component Subwoofer
A component subwoofer is the speaker itself. This needs to be mounted inside of an enclosure in order to perform properly as well receiving power from an external amplifier. Component subwoofers can range in size, typically from 8-15 inches. They have a wide variety to choose from when it comes to size, impedance, voice coils, and box installation options. If you’re building a custom system, this is the best choice.

Enclosed Subwoofer
This is a subwoofer that already comes in an enclosure, but still requires an external amplifier for power. Although this limits you when it comes to the number of speaker and box type choices you’ll have, it makes the process just that bit simpler for those who aren’t concerned with building a custom setup.

Powered Subwoofer
A powered subwoofer is essentially a subwoofer kit that comes with everything you need. This is when you purchase a subwoofer that comes in an enclosure with a built-in amplifier. These subwoofers tend to take up very little space in your car, but offer no real options for customization, and won’t always produce the best bass output possible.

Vehicle-Specific Subwoofers
These subwoofers are designed to fit in certain vehicle models, with the idea in mind of saving as much space as possible. They are often designed to fit in a vehicle-specific unused space, allowing them to be installed without intruding much into the interior room. These aren’t always the best choice when you’re looking for the best performance, but it varies from model to model.


Subwoofers require an enclosure in order to move air effectively. An enclosure or “box” allows for air pressure to build, creating stronger sound output. There are two main types of enclosures, sealed and ported. Sealed enclosures tend to deliver more precise and accurate bass while ported enclosures are especially good for high volume performance.

The power of a subwoofer is rated in RMS wattage which measures the amount of power the subwoofer can take before risking damage. The idea is to make sure that the RMS wattage rating of the subwoofer and the RMS wattage of your amplifier (measured in terms of how much power the amp can produce) match each other as closely as possible.

For example, if your subwoofer has a rating of 200 watts, your ideal amplifier would have a power output rating of 200 watts. This ensures the safety and longevity of all of your components.

Measured in ohms, impedance refers to the resistance of a circuit to the flow of electricity. Most subwoofers are rated at 4 ohms, but 2-ohm, 8-ohm, and others are becoming more popular. Without needing to understand electrical concepts, just keep in mind that like with the power rating, you want the subwoofer and the amplifier to match as closely as possible.

Voice Coils
Voice coils are what make the subwoofer diaphragm actually move, moving air and creating sound. Subwoofers typically have a single voice coil, but dual voice coil subwoofers are increasing in popularity amongst those seeking wiring flexibility for their custom systems.

Frequency Range
Measured in Hz, frequency range tells you what sort of sounds a subwoofer is capable of producing. The most important number to look at is the low end; the lower the number is, the more the subwoofer can do deep bass.

While most people focus primarily on the size of the subwoofer, it is not the most important factor to consider. However, after considering the type of subwoofer, the enclosure, and the power that you want, size does come into the picture.

When you have the space, bigger is usually better; however, a correctly-installed small subwoofer can add a tremendous performance upgrade. It’s usually much better to stick with a higher quality subwoofer that is smaller, as opposed to getting the largest you can afford/fit into your vehicle.
