Buying Guide For The Best Under Seat Subwoofer

There are a lot of improvements that can be made in the car audio systems. You can add additional speakers for surround sound, you can add an amplifier to get higher quality output, or you can simply add an under seat subwoofer to increase the low-end frequency output or, as more commonly known as, bass. While normal speakers can still offer a decent amount of bass, you can expect the lowest frequency response to be about 60 to 70 Hz.

On the other hand, a subwoofer can go as low as 20 Hz, which reveals a lot of low-end notes that would be hidden in the original system. There are a lot of other features like the frequency response that we have mentioned with each of our picks for the best under seat subwoofer. Thus, we will talk about these features in a brief manner on our buying guide for the same.

1. Size of The Subwoofer

The cone size of a subwoofer not only represents its physical size but also its overall capabilities to produce sound. Thus, it is the first thing that you should notice while selecting an under-seat subwoofer.

As you may already know, the driver inside a subwoofer moves to create the output. Therefore, a large-sized driver is able to push more volume compared to a lower sized version. You can find the subwoofers varying from 8 inches all the way up to 12 inches in size. But as you are buying one for your car, it is important to get an 8 inches or 10 inches version so that it will fit easily.

2. Frequency Response

Along with the power capacity, the subwoofer should be able to distinguish between various notes and provide distinct output for each/. This is only possible if your subwoofer is connected to a high-quality source input and supports a wide frequency range.

This way, the music that you are playing will not be compressed and will consist of a higher range of notes that could be played with your subwoofer. The lower value is generally more important in this case as it represents the bass in the sound. Therefore, it would be great if you pick an under seat subwoofer that supports the lowest frequency output.

3. Peak and RMS Power Capacity

With almost every sound output device like a subwoofer or a home theatre system, you will find 2 types of power ratings that might confuse a casual user. With every unit, you will find a certain RMS capacity and peak power capacity. While both of these values are present in the watts unit and indicate the power capacity of the unit, there is a difference in them. The RMS capacity is basically the ability of the speaker to provide continuous output, whereas the peak capacity is a higher value that is momentarily available on the subwoofer. Hence, both of these factors are important and should be considered carefully.

4. Physical Size of The Subwoofer

Installing any equipment in your car comes with the size concern. Unlike your home or office, there is not a lot of space available in a car, especially after installing all the necessary peripherals. If you are already running low on the available space in your car, it would be wiser to check the dimensions of the subwoofer before buying it. Even though it will be an under-seat subwoofer, it could create a lot of problems if it does not fit properly in your car. In general, the subwoofers that have a larger driver are larger in size.

5. Built-in Amplifier

We all know that subwoofers require a lot of power to operate. Thus, you will have to get a decent amplifier to power the subwoofer. The amplifier will make sure that it gets the necessary power and performs well even at higher volumes. Although, it would not be a lot of trouble if you go with an option that has a built-in amplifier. The built-in amplifiers are already tested on the subwoofers, so that you won’t need to worry about that. And if you are getting an external amplifier bundled with the subwoofer, it is nothing but a better value for your investment.


The home sound system consists of multiple units like primary drivers, amplifiers, and dedicated bass units. All of these units are important to enjoy the music to its fullest. The same is also required for cars. But, most users rely on the primary drivers for low end, which is not good enough for most systems.

Thus, a dedicated subwoofer comes into play in such situations. There are special small-sized subwoofers available for cars that can be installed in the excess space available below a seat. Considering the specifications and details provided in our list and the buying guide, here are our favorite picks:

  • If you only wish to get the best performance and bass delivery from your subwoofer, take a look at the Rockville RW10CA Under Seat Subwoofers. While it may be larger in size, it has a 10 inches driver and is packed with a peak power capacity of up to 800 watts. The minimum supported frequency for this subwoofer is 20 Hz which is very good.
  • It is quite difficult to find a high powered option if you are on a tight budget. Fortunately, we have the Planet Audio P8AWK Under Seat Powered Car Subwoofer that offers 800 watts peak power capacity, which is very good. Also, it is powered by an 8 inches driver that is warranted for a year after purchase.
  • Finally, we will recommend getting the Seventour Slim Under Seat Powered Car Subwoofer as it is a highly premium option. Seventour is a very reputed brand, and you will surely get a decent bass and low-end output from this subwoofer.
