What to Look for When Buying the Best Under Seat Subwoofer

So you’re convinced. You already want to head out in search of the best under seat subwoofer or click “order”. Just hold on a minute. Do you know what to look for? Everyone has different needs and preferences. To save you the headache of having to return the product because it doesn’t suit your unique needs and taking up a lot of time, we’re going to tell you what to look for to find the best under seat subwoofer for you. 

Power Handling

The power handling refers to the wattage. For those who like a deeper and louder bass sound and to crank up the music at high volumes, we recommend higher power handling. The higher the power handling, the more sound it can produce. So look for ones with high wattages, such as the Rockville RW10CA with 800 watts! However, you need to be realistic, the size of the subwoofer has a lot to do with the power handling. If you’re looking for bass that vibrates through your entire vehicle, then you shouldn’t go for an under seat option.

  • Peak Power – This refers to the highest amount of power the under seat subwoofer can handle in short bursts, but it doesn’t mean you get clear crisp sound. It just refers to the power the subwoofer can handle regardless of sound quality. This is where people think they have a faulty product because they experience distortion at the peak power.
  • RMS Power – The RMS power refers to how much power the amp can put out continuously rather than in short bursts. This is also the power wattage for how much power the under seat subwoofer can handle without damaging the product and causing sound distortion.


If you are looking for an under seat sub, then chances are your choices are dictated the space in your car. Think about where you are going to place it. Unfortunately, as mentioned above, the size of the subwoofer directly impacts its performance and installation. Subwoofers come in a few different sizes, ranging from 6 inches to 12. 8 inch subs are the most common because they take the best of both worlds and roll it into one. They save on space and have adequate performance. However, they may not be sufficient for heavy bass lovers.

Next up are the 10 inch options, which are also quite common. Since you do have more space under your seat, a lot of drivers choose the 10 inch over the 8 as they have a better bass response compared to the latter. They are also relatively easy to install.

12 inch subwoofers are less common, although they provide better bass and response than all the other sizes, only those who know exactly what they want will opt for the 12-inch. They take up more space and aren’t manufactured by many.


Not all under seat subs come with a pre-built amp, but most do. The amplifier helps the little subwoofer play louder notes than it otherwise would. This is exceptionally useful to have if you have smaller sized subwoofer and you like a booming bass. Need suggestions for a separate amp? Check our review of the best 5-channel amplifiers for 2020.


vFor all the bass lovers out there, the cone is another deciding factor for the performance of the bass. The larger the cone, the more air it can displace. This means the bigger cone you have, the louder and more powerful the bass will be. So choose one with a bigger cone like the Rockville RW10CA with its impressive 10 inch cone!


Some models we have suggested allow for customization of the bass levels etc. Is this something you are looking for or is the factory default setting enough for you? 


Whether you know what you’re doing or if you’re going in blind, you would want the installation process to be easy. Look at whether or not it’s easy to set up. Does it come with everything you need in the box?


Since you want bass, which is why you are installing an under seat sub. A lot of manufacturers will include the specs of the product, and one is the frequency. The lower the better in this case as it means your subwoofer can hit the lower tones. The frequency range is the range at which the subwoofer can function without sound distortion. Since heavy bass is at a lower frequency, you’d want a lower number on the frequency range.


A subwoofer with more sensitivity will be more energy efficient. It may also last longer as it uses less energy.

Thermal Protection

To keep you and your car safe, you need ample thermal protection. This is especially true if you love to crank up that beat. It’s easy for devices to overheat when they are overworked, so a good ventilation system is vital.


What materials are used to construct the under seat subwoofer? Make sure what you choose is tough, durable, and made to handle the bumps on the road.


As with any type of technology, we’d suggest buying an under seat sub with a guarantee, warranty or both. In case something happens or it comes damaged,  you are eligible for are replacement or a refund. It’s just good sense to be able to protect yourself, especially for something with a higher price tag.

Benefits of Under Seat Subwoofers

With all that said, what exactly are the benefits of these little devices? Let’s take a look.

  1. Their size and lightweight body, which contributes to their portability and your convenience. Since it’s lightweight, it won’t affect the performance of your car either. They can be easily stored in the trunk if you need a bit more room in your car. They just give you more options in general and can slip into tight spaces.
  2. They can also be relatively easy to install compared to the ones you need to mount. Most of them come with their own amp so there isn’t any need to buy them separately and take up even more space. Some are so easy in fact that all you need to do is plug them into the power source
  3. A speaker and amp combo could cost you a lot more than just the hideaway sub. They are the more affordable option for those looking for better audio quality that won’t cost an arm and a leg.

What is the Best Subwoofer for Sound Quality?

We are going to mention our top choice product one more time, the Rockville RW10CA is still by far our best choice. Considering its power handling, the size of the cone and the make of the entire device, we feel like it knocks all the other options out of the water and blows all other competitors.


Hopefully with our factors to consider list you have already figured out which subwoofer is the best for your needs. You can even jazz up a stereo with one. Remember that a lot of these options also have the same design in a smaller or larger size and with different handling power. Whichever you choose, if you are tight on space and are looking for something to satisfy your deep bass craving, an underseat sub is a good option. It does well in the sound department for the most part by pumping out thumping bass and it slides right under your seat!
