Best 8 inch Subwoofer (Reviews of 2019)

If you want a system that can give you decent levels of bass, you have no option but to install a sub. Unfortunately, not everyone has space in their ride for a behemoth 12-inch or 15-inch unit and an 8 inch model might be the best answer. Here are our picks for best 8 inch subwoofer.

The Best 8 inch Subwoofer of 2019

1.    Skar Audio VD-8 D2 8 inch Car Subwoofer

When it comes to installing powerful equipment that comes with a very reasonable price tag for the quality, Skar has been a go-to brand for many people for years. This particular shallow-mount dual 2-ohm unit is rated at 600 watts peak power or 400 watts RMS – and it can really make some noise.

If you are looking for an 8 inch sub because you don’t have the space for anything bulkier, a shallow-mount sub might be a great idea. These subs take up less space and so can be mounted in vehicles where you wouldn’t be able to fit a regular sub.

With its pressed paper cone, high-temperature 2” voice coil and single stack ferrite magnet, this sub is built to give you the power and quality of sound you require but in a smaller package. It is even shallow enough to mount under a seat but will still give you plenty of pounding bass.

On top of everything else, it retails at a very low price point considering the quality and power you are buying. Overall, this is a top pick for anyone who needs to compromise on space and budget but who don’t want to compromise on power or quality.

2.    Skar Audio IX-8 D2 8 inch Car Subwoofer (Our Top Recommended)

Here is another dual 2-ohm sub from Skar, this time a less powerful model rated at 300 watts peak power or 150 watts RMS. It features a pressed paper cone, a highly-effective cooling system to prevent it from overheating and high-temperature 2” copper voice coil.

This is another sub that bears all the hallmarks of the Skar brand, namely high build quality, reliability, power and clarity of sound – all at a more than acceptable price point.

As you would expect, once installed and properly broken in, this speaker will give you some very clean and clear deep bass that you can really feel.

Of course, in this category, you shouldn’t expect anything that will shake the whole car – but you will be able to achieve a very respectable amount of bass that will greatly enhance your listening experience compared to simply listening through a standard factory setup.

This is the kind of sub that should appeal to anybody who enjoys high levels of sound quality and some deep, rumbling bass but who doesn’t need to take things to extremes. Again, at this price point and for this kind of quality, you can hardly go wrong.

3.    Skar Audio VVX-8v3 D4 8 inch Car Subwoofer

For anyone who likes the sound of the two Skar subs we’ve already looked at but who needs a bit more raw power in their car, this model could be worth a look. This is a sub to consider if you need something small but that still packs a big punch.

It has a power rating of 800 watts peak or 400 watts RMS and incorporates many high-quality components, including a competition-grade pressed paper cone and a high roll foam surround.

The 2” high-temperature copper voice coil and the big triple-stack high-flux ferrite motor also help it handle plenty of bass with high levels of clarity and accuracy. In short, this is a unit designed for the best possible combination of sound quality and sound pressure levels in the smallest package.

If you want to add big amounts of bass to your onboard sound system but care about sound quality as well as just pure power in itself – and are also looking for a setup that gives you top bang for your buck – this powerful little sub from Skar should definitely be of interest.

4.    Pioneer TS-SW2002D2 8 inch Shallow-Mount Subwoofer

Best 8 inch Subwoofer reviews

Another of the most established brands in car audio equipment is Pioneer. Their products are routinely high-quality and reliable – and this 2-ohm, 8 inch shallow-mount sub is no different.

It is rated as being able to handle up to 600 watts of power peak or 150 watts of power RMS. It has frequency response of 20-200Hz.

As with all Pioneer products, it is a well-constructed unit and features an oversized mica-injected resin cone. This gives the cone and gasket a greater surface area, allowing it to displace more air and so creating a more powerful, deeper, cleaner and more accurate sound.

As a shallow-mount model, this sub is also designed to take up less space than regular subs of this size, meaning it would be a suitable option for smaller vehicles where space is more limited. This could easily fit under a seat or in a small trunk – wherever you have space.

This is a stylish-looking, affordable sub from a trusted brand that produces good levels of crisp, powerful bass. If these are the attributes you are looking for, this Pioneer could be the best solution for you.

5.    BOSS Audio CXX8 8 inch Car Subwoofer

If you want to add some extra bass to your system but are on a very tight budget, this entry-level sub from Boss could be what you are looking for. It is a 4-ohm model with a single voice coil that is rated at 600 watts of peak power.

For such an inexpensive unit, it is very well constructed. It features a polypropylene cone, a high-temperature voice coil and a butyl rubber surround, all of which ensure very respectable levels of sound, reliability and durability for such an inexpensive product.

While this obviously can’t be compared with subs that cost many times as much, this is still great value for money. In fact, for a sub at such a low price point, this one manages to punch above its weight in just about every department.

It is easy to mount, looks great and can deliver plenty of low, rumbling bass. This would be a good option for anyone who needs extra power in the lower frequencies but who doesn’t have cash to burn.

This sub would also appeal to someone who is taking their first steps into the world of upgraded car sound systems but who is not yet ready to invest the big bucks for a higher-end installation. A recommended sub at the lowest end of the price spectrum.

6.    JBL Stage 810 8 inch Car Audio Subwoofer

We’re big fans of JLB audio equipment. This is a company that regularly turns out affordable gear that offers big power and great bang for your buck. This 8 inch sub continues that tradition and is another option that’s well worth a look if you want to give your car’s bass a boost.

This is a 4-ohm sub with frequency response of 38-200Hz and with a power rating of 800 watts peak or 200 watts RMS. It is built to provide the highest levels of power and output with minimal distortion – all at the lowest price point possible.

This is achieved by using high-quality construction materials along with all JBL’s know-how. This sub incorporates a polypropylene cone with a high roll rubber surround for superior sound reproduction coupled with enhanced durability.

Overall, this is a sub for the kind of person who can afford to spend a little more than the absolute minimum but who demands great value and high levels of performance. This won’t compete with top-end subs, but in this category, you could do a lot worse than choose this JBL.

7.    Kicker CompR 8 inch 4-Ohm Subwoofer

This 4-ohm, 8 inch sub from Kicker is a great option in the lower mid-range price category. It is rated at 600 watts peak power or 300 watts RMS and can provide your in-car sound system with all the growling bass you need to complement the rest of your set up.

Kicker equipment is always well-constructed, and the quality of the components in this sub show why. It features a double-stacked magnet, a polypropylene SoloKon cone and a Santoprene surround. The cone and surround are double-stitched together to hold them firmly in place.

This speaker is built for durability and reliability and it is made to be played loud for as long as you want. As with some of the other subs we’ve looked at, although this is not a high-end competition sub, it will still give you plenty of big pounding bass for everyday listening.

If you are looking to install something in your car that will produce bass you can feel all through your body but without reaching extremes that will vibrate inside your brain, this could be the right pick for you. A very decent sub.

8. Massive Audio Hippo84 8 Inch Competition Subwoofer

This monster from Massive Audio is another great option for anyone looking to upgrade their car’s bass – essentially, this speaker features near competition-level materials and build quality but at sub-competition prices.

It features a large high-energy double-stacked strontium magnet, a tough and durable cast-aluminum basket, a Nomex spider and an anodized voice coil with Kevlar spunlace.

These superior components allow it to produce deep, crisp and powerful bass of a quality that is unusual in a sub in this category and price range.

If you are looking for the kind of tight bass you would expect from a higher-end sub but would prefer to pay a lot less to obtain it, this sub should definitely be high on your list of possibilities.

9.    Rockford Fosgate P3SD2-8 8 inch Car Subwoofer

When it comes to well-known brands in the North American car audio field, Rockford Fosgate is up there with the very best of them. They have been producing high-quality products for over 30 years and this dual 2-ohm, 8 inch sub can be comfortably placed on that list too.

It is a shallow-mount model, requiring only 211/16” to fit. Despite this lack of depth, it still packs a powerful punch, with a rating of 300 watts peaks or 150 watts RMS. Frequency response is rated at 38-250Hz.

Rockford Fosgate’s equipment is always well-made, reliable and built to last, and this sub is no exception. However, the highlight here is the sound quality.

Although it can’t produce the raw power of some other subs, what you can expect is some smooth and accurate lows that will greatly enhance your listening experience.

With a lower power rating than some other subs, this is perhaps not the sub for those who want their whole neighborhood to hear their music – but for those looking for something impressive but less extreme, this would be an ideal pick. Good value for money.

10.  Rockville RW8CA 8 inch Car Subwoofer

If you want to give your car’s sound system an extra level of bass but you also want to keep things as simple as possible, this powered under seat sub from Rockville could be just what you need.

Since it’s a powered sub, you won’t need to worry about hooking it up to a separate amp – the amp and controls are all built in. It’s rated at 600 watts peak or 150 watts RMS, and there’s a sub remote and bass boost of 0-18dB at 45Hz so you can easily customize just how you listen to your music.

There are also plenty of features to keep the amp safe, including thermal protection, short protection and overload protection circuits.

This would be an ideal option for someone who needs a sub that will fit comfortably under their seat due to space limitations and who doesn’t want to have the hassle of setting up a system with lots of different components.

It’s easy to install, gives great-sounding deep and crisp bass, sells for a very reasonable price – and is even one of the best-looking units we’ve seen. Another great option that gets out approval.

Some big power in small packages

While compact 8 inch subs can’t always compete with the bigger models that are available, there are some notable units that still pack quite a punch. If you’re looking to fit some extra bass into your car but don’t have space for bulkier equipment, smaller options still exist that will do the business.
