Are you dissatisfied with the sound your car speakers are giving out? If so, it may be time to consider giving your car’s sound system an upgrade.

Factory or OEM stereo systems do not have the optimum speakers present in more expensive automobiles. Almost every car audiophile can attest that factory speakers don’t always produce quality sound.

In some unfortunate cases, they either produce shrill sounds or muddle and slur the vocals, subduing the great sound of the music.

This is why you need the best 15″ subwoofer for your car.​

It’s hard to admit but your car’s audio system can greatly affect your overall driving experience and mood. Every low, mid, and high of the music matters.

Just imagine if you’re listening to your favorite song and not hearing important tones throughout the whole song. You’d notice it right away and actually feel a bit disappointed, sometimes disheartened.

Luckily, new speaker options are available for those who’d want to give their sound systems a lift. One example is a subwoofer for cars.

What’s a Subwoofer?

A subwoofer is an automobile speaker that reproduces low frequency sounds, to achieve the best possible bottom two octaves. Many people associate subwoofers with the loud, thumping, and bone-shaking noises, but they really just amplify and perfect the low tones given out by the music track or file.

It’s not always enclosed in a certain corner of the car or in any compartment, but it’s actually just bellow your car’s woofer or other sound systems.

Subwoofer Advantages

Better Listening Experience

Most certainly, built-in speakers in automobiles leave much for improvement, such as louder volumes and clarity of sound. With a subwoofer installed, you’ll surely hear rich bass tones and a more extensive bass range.

Likewise, the midrange becomes clearer and cleaner for the listeners. Whether the bass tones are in the lowest levels or at the peaks, the subwoofer could surely play them without strain.

Bass Emphasis

Generally, car speakers are made to amplify sound, with no specifics. A subwoofer can specialize on the bass range and even diffuse sounds that may seem off the track.

It’s there to properly enhance low-pitched sounds. It also allows smaller speakers to handle the lowest extremes of frequency.

Additionally, a subwoofer mjnimizes vibrations felt inside and outside your car, as can be observed when a sudden loud and booming sound plays.

Bass is Heard by Both Ears in the Car

Maybe you’ve noticed that there are certain sounds and noises you can hear louder on a certain ear. This is because speakers distribute the frequencies and diffuse them in different ends.

The notable characteristic of bass tones is that they are non-directional. It simply means that the direction of the range is not only restricted to one ear.

With a subwoofer, the car can enhance sound that could be heard from all over the car.

What to Look For


Size definitely matters when it comes to subwoofers. The principle is, the bigger the subwoofer you install in your car, the better the bass tones will be.

Settling for the smaller units might give a slight improvement on the audio systems, but why spend and settle for less?

On the one hand, space might be a concern for the car owners. Don’t forget to take measurements for the compartments allotted for these sound system accessories.

Enclosure type​

The type of enclosure a subwoofer will be placed in has a great impact on the resulting sound. If you are an afficionado of loud flowing music, choose the ported ones to have maximum volume.

On the other hand, if you really appreciate the depth and accuracy of bass tones, opt for the sealed ones instead.


Paying attention to the subwoofer’s power also means paying attention to the continuity of quality music.

What you should really look out for is the RMS or Root Mean Square of the subwoofer. Make sure that if the RMS is high, the amplifier that powers it can keep up with the needed output.


Impedance, simply put, is the resistance offered by circuits and is measured in ohms. Contrary to the size and power, a lower impedance is better for your subwoofer.

Lower impedance, such as 2 ohms, means that there will be less resistance to produce output or sounds. But the usual impedance on subwoofers are in 4 ohms.

A subwoofer system is very effective in achieving quality music. However, poor installation and substandard products could compromise all the benefits they are supposed to serve.
