Car Subwoofer Buying Guide

Before we conclude our reviews we are going to take a moment to go through some of the key information related to subwoofer purchases in an effort to wheedle out what is important to know before you buy.

What is a Subwoofer?

A subwoofer is a very low frequency producing speaker, containing one or more woofers sometimes called a loudspeaker once housed. They are specifically designed for handling bass sounds and sub-bass frequencies. They are used in many set-ups from desktop computer speakers, home cinemas, home studio speaker set-ups, concerts, festivals, and raves.

While standard speaker sets will cover a broad range of audio output, any setup will have an instantly noticeable difference with the inclusion of a subwoofer handling the lower, thumping ranges.

They are built to capably withstand the sound pressure level (SPL) of low end sounds played at high decibels and were originally created to save traditional speakers from lower, louder damaging frequency pressures.

They move large volumes of air and often require a lot of power. It is fairly simple to generate high volume bass over a small bandwidth and many cheap car subwoofers to buy do exactly this, creating studio level sub-bass is a little trickier and requires more powerful amplification or a larger bass driver/several small ones.

Subwoofers all function in a very similar simple way but the styles and specifications differ and it can sometimes be difficult to pick apart the pros and cons of each.

How Do Subwoofers Work?

Most commonly subwoofers are electromagnetically driven. They house a stiff cone driven by a single voice coil centered in a magnetic field.

The single voice coil is attached dot the back of the speaker cone and it moves when current flows through it pushing and pulling on the driver cone which moves in and out like a piston, creating waves as it is in motion.


Typically they are circular as with the majority of speakers this is an ideal shape for funneling directional sound where you want it. It also produces a cleaner sound far less distorted than other shapes which some companies developed In the early 2000s.

Other shape options were initially explored for car use because ultimately a car is not well suited for typical loudspeakers. A decent loudspeaker actually requires a fair amount of space to function to the best of its abilities. Bass cabinets (bass bins) that house loudspeakers for concerts are sometimes larger than the trunk of a car.

The displacement volume is what reproduces loud low frequencies and without space, the displacement is not as impactive as it could be.

Non-circular shapes allow for bigger cone areas in limited mounting space situations but at the sacrifice of sound quality. The louder you go the more the sound will distort.

Another key factor with subwoofers is the room they are in and it's natural acoustics, which you can probably guess a car isn't half as suited for as an auditorium or theater.

Sizes: 10-Inch Subwoofers Vs 12-inch Subwoofers

The range of sizes goes from 8-inch subwoofers to 21-inch subwoofers for typical commercial use. When it comes to using in cars audio, by far the most common is the tens or twelves, with outer measurements respectively in inches. The best car subwoofers aren't always the biggest, there will only be minor differences within the actual audio outputs in the different sizes, this usually being more dependent on power, but as you increase the size of the bass cars speakers itself you will, of course, increase its output.

One key factor to bear in mind when picking the size of your speaker set up is to make sure the boot of your car is large enough for any power subs you want to be installed, and you must bear in mind, enclosures will also take up further space.

Type Of Enclosures

Some subwoofer car accessories you buy housed in an enclosure already other car accessories are solely the subwoofer to add to your own build or replace previous woofers.

The enclosure style can actually have more of an impact on the performance of the subwoofer than the diameter size difference. Speaker enclosures in general (all types) need to be able to successfully separate the sound waves projects forwards from those at the rear because otherwise, the two cancel one another as they will be out of phase and produce a terrible bass response. This is especially true for low-end frequencies and so the right enclosure is all the more important for subwoofers.

Usually, the drive of a subwoofer is placed hidden inside of a bandpass cabinet a tuned box that can resonate efficiently this is what we see in typical home set-ups. The majority of powered car subwoofers adopt a reflex design over a closed box design.

Bass reflex type of enclosures is sometimes called ported enclosures or vented box or even reflex port. Ported enclosures employ a hole with a section of tubing or pipe the two work in harmony like a pipe-organ. If they are built with accurate volume calculations they can be louder than a sealed enclosure.

The math, for those interested, is explained in this Youtube video


The equation is based on the Thiele/Small parameters and also takes into consideration Hoffman's Iron Law. The fundamentals of the equation take into account projected area of the diaphragm of the driver, the mass of the parts, compliance of the drivers suspension, Its mechanical resistance, The voice inductance, the volume of air and much much more.

Passive Vs Active?

Passive subwoofers contain a subwoofer driver which is powered by an external amplifier, they typically have internal passive crossovers. Active ones have a dedicated subwoofer amplifier built-in.

What is the RMS Power Rating?

RMS stands for Root, Mean Square is a statistical measurement of voltage or current. The RMS power rating with powered car subwoofers is to give an indication as to the highest possible measure of continual power which the speaker can handle.

How to Install A Subwoofer In A Car?

How to install your subwoofer depends on whether you bought a bare subwoofer or one already enclosed. As installs go they are relatively simple, thanks to the popularity of the SPL wars they are copious amounts of DIY instructional video's available online.


If you are still unsure you can seek a professional, there are millions of garages or mechanics worldwide capable of putting in all the connections and making sure everything is neat and working.


As you have probably concluded yourself there is far more involved with choosing the right subwoofer for your car than perhaps first gleaned. If you are struggling to make sense of the logistics behind your own type of enclosures opt for something already contained. If you are building your own seek some advice, fortunately, today the popularity of the SPL wars has led to a whole subculture of extreme car 'suping' so there is a wealth of material on the subject available online you can learn from others mistakes and benefit from their trial and error knowledge. There are some amazing low-cost car accessories out there to give your car a sufficient bass boost.

It is important to remember that less is sometimes more as far as audio quality is concerned. The next important factor is the enclosure really is key the most expensive speaker from some of the best car subwoofer brands, in the wrong enclosure will sound awful and vice versa, so size and money aren't factors that weigh in too heavily here. We hope we have provided you with sufficient food for thought and a few fantastic options to consider for purchase.

Expert Tip

Although the human ear only detects a certain range of frequencies using sub bass tracks and amplifiers at loud volumes can have irreparable effects on your hearing so we ought to warn you about the dangers within an enclosed space such as your car you are at risk of Tinnitus as well as low frequency hearing loss altogether the sensitive hairs in your ears die over the course of your life as they are exposed to individual frequencies overexposure reduces the longevity if you listen to a lot of basses ultimately you will lose your lower range of hearing earlier than most people begin to.

Did You Know?

Sub woofers are part of speaker amplifications long history and some of the biggest were originally created in the 60/70's for adding extra tension in movie theaters for jump scares
