Car Subwoofer Buying Guide

We will take a moment to go through some of the main details relevant to subwoofer purchases before we conclude our reviews, in an attempt to wheedle out what is important to know before you buy.

What is a Subwoofer?

A subwoofer is a speaker that generates very low frequency, containing one or more woofers, also called a once-housed loudspeaker. They are designed specifically to handle bass sounds and sub-bass frequencies. They are used in many set-ups including desktop computer speakers, home cinemas, home studio speaker set-ups, concerts, festivals, and raves.

While standard speaker sets will cover a wide range of audio quality, with the addition of a subwoofer handling the lower, thumping ranges, any system will have an immediately noticeable difference.

They are engineered to withstand the low-end sound pressure level (SPL) of low-end sounds played at high decibels and were initially developed to save conventional speakers from lower, louder, damaging frequency pressures.

They transfer huge air volumes and need a lot of power sometimes. It's very easy to produce high volume bass over a limited bandwidth and to buy several cheap car subwoofers to do just that. It's a little trickier to produce studio-level sub-bass and needs more efficient amplification, a bigger bass driver, or many small ones.

Subwoofers all work in a very similar way, but the designs and requirements vary and the pros and cons can often be hard to pick apart.

How Do Subwoofers Work?

Subwoofers are most generally, electromagnetically powered. They contain a rigid cone driven by a single magnetic field-centered voice coil.

Attached to the back of the speaker cone is a single voice coil. When the current runs into it it shifts. Push and pull on the driver cone that moves like a piston in and out, generating waves as it's in motion.


They're usually round, as with the majority of speakers. For funnelling directional sound where you want it, this is an ideal type. It also creates a clearer sound that some businesses produced in the early 2000s, much less distorted than other shapes.

Initially, other shape choices for car use were discussed because, essentially, a car is not well suited for traditional loudspeakers. In reality, a good loudspeaker needs a reasonable amount of space to operate to the best of its capabilities. Bass cabinets (bass bins) that contain concert loudspeakers are often larger than a car's trunk.

The amount of displacement is what reproduces noisy low frequencies and the displacement is not as impactive as it might be without space.

In restricted mounting space circumstances, non-circular shapes allow for larger cone areas, but at the expense of sound quality. The louder you go, the more distorted the sound will be.

The space in which they are and its natural acoustics are another key consideration for subwoofers. You will possibly infer that an auditorium or theatre is not ideal for a speaker for a vehicle.

Sizes: 10-Inch Subwoofers Vs 12-inch


The selection of sizes for standard commercial use goes from 8-inch subwoofers to 21-inch subwoofers. When it comes to using in cars audio, by far the most common is the 10-inch or 12, with outer measurements respectively in inches. The best subwoofers for cars are not necessarily the strongest. There will only be small variations in the various sizes of the real audio outputs. This is typically more dependent on electricity, but you can, of course, increase the performance when you increase the size of the bass speakers themselves.

When choosing the size of your speaker set-up, one main consideration to bear in mind is to ensure that your car's boot is big enough for any power subs you wish to add. You have to note, enclosures can take up extra space as well.

Type Of Enclosures

Some subwoofers you purchase are already installed in an enclosure; others are just the subwoofer, which you can add or replace previous woofers to your own build.

Actually, the enclosure style may have more influence on the subwoofer's output than the difference in diameter size. In general, speaker enclosures (all types) need to be able to distinguish the forward projects of sound waves from those at the rear effectively because otherwise the two cancel each other out. They're going to be out of phase and generate a horrible response from the bass. For low-end frequencies, this is particularly true. So the correct enclosure for subwoofers is all the more relevant.

Usually, a subwoofer's drive is concealed within a tuned box that can echo easily inside a bandpass cabinet. In traditional home set-ups, this is what we see. A reflex design over a closed box design is followed by the majority of powered car subwoofers.

Ported enclosures, vented boxes or even reflex ports are often referred to as bass reflex enclosures. Ported enclosures use a hole with a tube or pipe section; the two operate like a pipe organ in harmony. They can be louder than an enclosed enclosure if they are designed with correct volume measurements.

In this Youtube video, the math for those interested is clarified.

The equation is built on the parameters of Thiele/Small. It takes Hoffman's Iron Rule into consideration as well. The basics of the equation take into account the estimated area of the driver's diaphragm, the mass of the parts and the suspension compliance of the driver. It also includes mechanical resistance, inductance of the voice, air volume, and much more.

Passive Vs Active?

A subwoofer driver that is driven by an external amplifier is present in passive subwoofers. Usually, they have passive internal crossovers. The successful ones have a built-in dedicated subwoofer amplifier.

What is the RMS Power Rating?

RMS stands for Root, and Mean Square is a voltage or current statistical calculation. With driven car subwoofers, the RMS power level provides an indication of the maximum possible continuous power measure that the speaker can accommodate.

How to Install A Subwoofer In A Car?

If you've purchased a bare subwoofer or one already enclosed depends on how you should mount your subwoofer. They are relatively straightforward as installations go. There are vast quantities of instructional videos available online due to the success of the SPL wars.

https:/www.youtube.com/watch/watch? V=TzPbEaKmQyggEaKmQygg v=

You should look for a specialist if you are still uncertain. Worldwide, there are millions of garages or mechanics, all able to put in all the ties and make sure it is neat and running.


There is much more involved in finding the right subwoofer for your car than maybe first gleaned, as you have probably concluded yourself. Choose something already enclosed if you're trying to make sense of the logistics behind your own kind of enclosures. Look for any suggestions if you are constructing your own. Fortunately, the success of the SPL wars today has led to the 'suping' of a whole subculture of extreme vehicles. This means that there is a wealth of material available online on the subject. You can learn from the errors of others and benefit from their experience of trial and error. To provide your car with a sufficient bass boost, there are some awesome low-cost car accessories out there.

It's important to note that as far as audio quality is concerned, less is often better. The next critical thing to consider is that the secret is really the enclosure. The most expensive speaker in the wrong enclosure, from some of the best car subwoofer brands, would sound bad and vice versa. Size and money are not considerations that when it comes to tone, weigh in too much here. We hope we've provided you with enough food to think about and a few great choices to consider for purchase.

Expert Tip

Since the human ear uses sub-bass tracks and amplifiers to only perceive a certain range of frequencies, loud volumes may have irreparable effects on your ears. We should alert you of the risks of listening in an enclosed area, such as your vehicle. As well as low-frequency hearing loss, you are at risk of tinnitus altogether. Over the course of your life, the sensitive hairs in your ears die when they are exposed to individual frequencies. Longevity is decreased by overexposure. Ultimately, if you listen to a lot of basses, you will lose your lower range of hearing faster than other individuals begin to.

Did You Know?

Subwoofers are part of the long history of speaker amplifications, and some of the largest were originally created in the 60/70's to add extra tension for jump scares in movie theatres.
