An under seat subwoofer is perfect If you’re someone that can appreciate high-quality sounds and deep bass in your music, but might feel a bit put-off by your car’s standard sound system. Many cars come with a basic sound system that doesn’t quite have the bass depths or sound quality you may be looking for to play your music from. Subwoofers are much simpler and less expensive than replacing your whole sound stereo system and also take up very little space, hence the name, under seat.
You don’t have to place these subwoofers under your seat though, they are portable and slim enough to be placed anywhere in your vehicle, without having to take up any valuable space. With a large range of these booming audio additions around, we’ve selected our 5 top subwoofers for under your car seats below.

Subwoofer for Under Car Seats Buying Considerations
An under seat subwoofer isn’t going to wake up your whole neighborhood, regardless of how powerful it may be. But they will add a significant amount of bass to your sound system and improve your overall sound quality during your drive. There are two power ratings that you should pay attention to in particular, and those are the peak power and the RMS power.
This represents the maximum wattage that the subwoofer can handle in short bursts. If an amp ever produces more watts than your subwoofer can handle, it can cause sound distortions. Additionally, your subwoofer can suffer actual damage and may even short out altogether.
This rating is just as important and has more to do with consistent sound quality. This is the actual wattage that the subwoofer can channel without producing distortion or suffering any harm to the actual equipment. You absolutely must consider the RMS power rating into account when you’re pairing an amp and a subwoofer. The closer the amp and subwoofer values are to one another, the better your sound quality will be. You want your amp to produce somewhere between 75 percent and 150 percent of your subwoofer’s watts for optimal performance.
One of the most important parts of buying a subwoofer is to sort out where it will be installed in your car before you even purchase it. If you don’t plan and prepare ahead of time, you may end up buying a subwoofer that won’t even fit in your vehicle where it should. Different makes and models and cars can accommodate different sizes and models of subwoofer, but there are some general guidelines you can follow.
For Sports Cars
You’re working with a smaller car off the bat. You should take that into account and assume you’ll be buying the 8-inch subwoofers. There are some 10-inch models that will also fit, but keep in mind that it’s very likely that they will reduce and restrict space for those riding in the car.
You have a bit more space to work with. Typically, though, you should still look to get either an 8- or 10-inch under seat subwoofer model. This is because the 12-inch models, while they might fit, will take up more space and restrict your usable space.
For Trucks and SUVs
You typically will have the maximum amount of available space to work with and can choose multiple smaller subwoofers or invest in the 12-inch models if you’ve got a large enough truck or SUV. You should still measure the space under your seats to be sure you can accommodate the subwoofer, just to be safe.
The size of your subwoofer is key in deciding how it will function and behave. There are three standard under seat subwoofer sizes that you’ll come across when you’re searching for the best fit for your car.
This will provide fantastic clarity and bass response, but they won’t typically add very much bass to the music you’re playing. These are the most common size of subwoofers and are the smallest size available.
These are fairly common as well for cars, and people purchasing aftermarket subwoofers tend to go for this medium-sized option. They are not difficult to install. These subwoofers have a great bass response and decent clarity, and will produce more bass than the smaller 8-inch models will.
They are not very common at all and are the largest of the available subwoofer sizes for under seat subwoofers. They produce decent bass response and clarity, but produce the most bass out of the three available sizes. However, these models are harder to install because of their large and non-standard size, so keep that in mind.
The Final Word
If you’re short on space in your car, don’t have the technical knowledge required for audio wiring, or simply don’t have the budget to invest in a new stereo system, an under seat subwoofer might be worth investing in if you’re after that extra bass sound. All of our best under seat subwoofer models reviewed above give off a nice bass sound and have a nice slim build to them. Just be sure to measure up the space you have available under your car seat or planned installation area before purchasing a model.
