What to Look for When Buying the Best 8 Inch Subwoofer?

A lot of factors contribute to how we deem a subwoofer to be good enough. Yes, anyone can say a subwoofer is good by listening to the sound it produces. However, that is all subjective since people have different needs and preferences when it comes to bass level. Luckily, there are a few ways you can determine whether a woofer is good or not. Read on to find out what they are!

Frequency Range

The frequency range basically means the range it can achieve. The lower the first number is, the lower the frequency, which means the lower and deeper the sound it can produce. Look for lower range frequencies in the 20-30 Hz range for the best deep bass sounds. Basically look at it like this, if you are a fan of deeper bass, then look for a lower number. Again, as mentioned before, how much bass and how deep and rich the bass is is personal preference. We have offered some options above that vary in this range for you to have more options.

Voice Coils

You have often seen subwoofers being advertised as having single or dual voice coils. We recommend dual voice coils if you need to add other drivers, and they allow for more customization flexibility in the future. Here’s help on how to install a subwoofer to a factory stereo.

Single voice coils are simpler and better for those who just want a quick upgrade, aren’t very tech savvy and won’t add any upgrades in the future

Does it Need an Amp?

Powered subwoofers usually have a speaker and an amplifier and maybe even a magnet for an extra boost of power. A powered sub is not for those who own smaller vehicles and may not have room for a separate amp. This is something to consider if you are limited in space. 

While the powered subwoofers do have decent sound and frequencies, the smaller enclosure has a negative impact on their ability to hit the deeper and brassier notes. Although on the flipside, they are easier to install.


Some of these smaller subwoofers come with an enclosure and are pre-mounted for your convenience. Keep in mind that pre-mounted subwoofers do not include amplifiers, so if you are looking for a powered subwoofer, keep this in mind.

If you need an enclosure to mount it inside your car, the ready-to-go enclosed subwoofers are an easier choice. However, they are less seen on the market.

Component or Non-Component?

Component subwoofers give the audiophile more room and options for customization. It isn’t the best choice for those who are less savvy with technology. Component subwoofers give you the option of choosing enclosure, amplifier (read our great 5-channel amp recommendations), and other items to tailor-make your own system. A non-component option already has everything you need in one ready-to-use package.


As we say for every product we review, a warranty or guarantee or both is extremely important as it gives you more protection. Who knows if you will receive a faulty, damaged or even the wrong product on delivery? If you find you have made the wrong choice, you can also have the choice to return it, refund it or exchange the product. Some even come with lifetime warranties, so it really is a winning situation.

Are 8 Inch Subwoofers Good?

There are a few different sizes on the market with 10 inch subs being the most popular. So should you go for an 8 inch? 

Of course, the larger ones pack more power but they do need more space. Sometimes you aren’t at liberty to choose if you just don’t have the allotted space. 

They don’t use as much power as their larger counterparts and will also save on your car battery, too.

So our verdict is, if you don’t have the space but want an adequate subwoofer with decent sound, yes, 8 inch subwoofers are good.

What is the Best Small Subwoofer?

We gave you our top pick above, but if you are looking for another suggestion, the Pioneer TS-SW2002D2 8-Inch Shallow-Mount Subwoofer is a strong contender. It’s quite shallow in design, is easy to install, and has pretty good bass if you ask us.

Extra Tip

There are also subwoofers designed to fit into specific areas and locations of your car. You have under-seat subwoofers, and subs that work well with different types of cars such as hatchbacks, SUVs, etc. Most of them do not come with a mount, so for people who need a bit of help, it’s better to get them professionally installed


Looking for a subwoofer can be like reading through a manual in another language for those of us without any prior experience. Keep in mind our factors to consider and hopefully that will help you make the right choice. One thing is for sure, we all need better bass than our standard car speakers can provide. Need a subwoofer that enhances bass without needing much modification in your car? Might be best to check out our dedicated list for this purpose.
