Best Under Seat Subwoofer: Editor’s Top Picks


Things to Consider When Buying an Under Seat Subwoofer

We know how excited you are to get your hands on one of the units that we have included in our review section. But before you pick any of them up or any other one from the market, there are certain things that you would have to keep in mind. They are as follows:

  • 1. Power Supply

Before anything else, you need to consider the power supply of the unit. Usually, the higher the rating is on the power supply, the punchier the bass. However, in some cases, the ones that do not have that much power supply but are highly efficient can also offer punchy and clean bass.

So, in this case, before you pick one of the high-powered ones, make sure that they are capable of using all of the power. If you do not want to go through this hassle of scrutinizing the power, we recommend you opt for the units that pack a Class D amp. Those are usually extremely efficient and can output relatively punchy bass.

  • 2. Noise Filter

Aside from the power of the unit, the quality of the bass will also depend on the filters that it comes with.

If you happen to get something that does not have any built-in filters, it would be highly likely that the sound it will produce will be full of noise in high volume. And you would not want noise ruining your music listening experience, would you?

That is why you should opt for the ones that have a built-in noise filter. With those, the sound is going to get filtered before it is produced from the diaphragm.

  • 3. Low Pass Filter

Another filter that you will have to check when you are buying one of these is the low pass filter. Much like the noise filter, this circuit will filter out the frequencies. It will remove any of the frequencies that are lower or higher than what the woofer is capable of outputting.

As a result, there would be a substantially low amount of distortion in the sound. Even if you do like to listen to music at a high volume, these filters will be able to provide bass with virtually no distortion at all.

  • 4. Inputs

In the case of inputs, there are usually two factors. One of them is the low level, and the other is the high level. Usually, the low-level inputs are the RCA interconnect inputs.

On the other hand, the high-level inputs are the standard speaker input. Even if you do not really need low-level inputs, we would suggest getting one that has both the inputs.

With the ones that can take both inputs, you will have the flexibility of connecting it with many of the speakers. As a result, you would not have to worry about compatibility that much.

  • 5. Size

The main purpose of getting one of these is to make them fit under the seat. And in that case, if you happen to get one that is not compact and does not have a slim profile, you will have difficulties in the case of making them fit under seats.

Keeping that in mind, you should only go for compact ones that have a slim footprint. You will be able to install them without any issues at all.

  • 6. Build

Durability is something that you would have to prioritize when buying one of these. In this case, the ones that we would recommend are the ones that are made of high-quality aluminum.

Those will not only be durable but also will be lightweight. And because of being lightweight, it would not be a problem for you to move them around.

Alongside that, many of these will sport a steel body. Even though they are more durable than the aluminum ones, they are going to be a bit hefty. So, if you think that durability is something that you will go all-in, then those are the ones that we would recommend to you.

  • 7. Protection

If the components that are inside the woofer are not well protected, no matter how durable the exterior is, you would not be able to get extended use out of it.

Considering that, you should check whether the one that you are shooting for comes with voltage protectors or not. Without those, the power supply will have a high possibility of getting damaged.

Aside from that, you should also consider whether it features overheating protection or not, especially if the one you are going for has 500 watts plus peak power. That protector will ensure that the components do not get damaged because of overheating, eventually ensuring an enhanced lifespan of the core components.

FAQs: Frequently Asked Questions


Q1: Are under-seat subwoofers worth it?

Considering that there is not usually much space available in the car to install high-end and large music systems, we would say that they are very much worth it. The powerful and efficient ones can give punchy and clear bass that is comparable with the large high-end systems that are out there.

Q2: What is the function of an amplifier?

Just like the name suggests, an amplifier will amplify the signals. As a result, the lower frequency will transform into a high frequency. This amplification of frequencies will result in clean and high-volume sounds.

Q3: Is an amplifier important for woofers?

Yes, an amplifier is very crucial for the sub-woofers. As you know by now, amplifiers amplify the signals. And without amplification of the frequencies, you would not be able to get any bass out of the music that you are playing.

Q4: What does the power of the amplifiers state in the case of subwoofers?

In the case of subwoofers, the more powerful the amplifier will be, the punchier bass it will be able to produce. However, the bass might not always be noise and distortion-free. For those factors, the power of the amplifier has no role at all.

Q5: Are low-level inputs absolutely necessary for subwoofers?

Not really. The low-level inputs are generally the RCA interconnect inputs that old-style speakers usually have. Most of the speakers that are available now have the high-level connector, which is basically a standard now.

So, if you do not have speakers that have a low-level connector, you should not worry that much about not having low-level input ports.

Q6: Do 4ohm devices output more bass than 2ohm ones?

Usually, lower electrical resistance will output louder sounds. In that sense, it can be said that the 2ohm devices will output punchier bass than the 4ohm ones. Though the 2ohm ones will produce louder sounds, the clarity is something that will be lower than the 4ohm units.


Final Thoughts

Getting the best under-seat subwoofer is basically the only option you have if you want to enjoy a high-end music listening experience. And if you have limited space in your car, then this device will be perfect. So, we hope that our comprehensive list had at least one product that you are now in love with.
