Sample Customer Review:

“I wanted to feel my music again. And hear songs in a harder bass hitting way. THis does the job. Like people have said this isn’t for insane break your windows bass. It is for adding more low end under or behind your seat for that “concert feel”. That is what my son called it after sitting with me in the truck for a bit. I ended up having it right behind the seat since on my truck with the electric seats there isn’t a way to fit them under.

But i am fine with that wanted it to vibrate my back not my bottom. And it does, on max my back will become numb. At first i thought i had hooked it up wrong or i got a bad one. Because i was not getting any sound. Found out that i needed to go into my stereos settings and up the volume to the sub.

That did the trick. Was worried that this small speaker wouldn’t be enough bass for me but it is really a decent amount. Don’t let the size fool you. And make sure to check your settings on your stereo.”

Sample Customer Review:

“I was initially extremely disappointed. The sub wouldn’t even generate bass enough to keep up with the factory setup in my wife’s 2019 Blazer, let alone enhance the bottom end. I even ran the sub up to full volume for a moment just to be sure, and it was simply not there.

I continued to play with phase, volume, and some light eq tweaks and, finally, it came to life (amp volume set to 6/10). This thing is actually pretty amazing for its size. Very punchy ..within reason. The biggest limitation is its ability to replicate notes below 50k but you cannot expect that from something so compact.

If you are looking to keep a factory setup and make it more enjoyable, this is worth the money. You have to be patient but you will be impressed. If you want to just take this out of the box and expect it to perform a miracle without some thoughtful adjustments, then you will probably be let down.

I ultimately purchased a second one to balance out the sound since I could feel the bass pulling to one side. This truck sounds so good now considering there are no visible amps or subs to take away from the use of the vehicle. I am very happy I took a chance and bought this. My wife is absolutely thrilled with the results.”

“This was exactly the right addition to my 2015 Toyota Tacoma to round out my stereo upgrade. It provides just enough power and bass to even out the sound and gives concert quality audio in a small space. Super easy to install and just right for a basic upgrade.

If you want a bass that really “hits” this is not the option for you, but if you want to make sure that your low end keeps up when you crank the volume and you have just enough to “feel” the music in your chest then this application should work well for your system. Very pleased.”

This setup only takes up a little more room than the old amp did and sounds almost as good. Well worth it to have the extra space. Really adjustable too.

“I don’t write reviews unless I really feel the need to. This little thing impressed me. No, it’s not gonna blow you out of the car but it only took an hour or so to install in my old suburban with factory head unit. I just tapped into the speaker wires and ran a power cable to it (power cable and fuse are not included in the kit by the way) but it sounds great. It’s way more powerful than I expected.

I just installed though, We’ll see how long it holds up but it does seem well built. For an 8” sub I can fit under the seat. I’m very impressed so far."


There’s a good reason why many people go to great lengths trying to find a perfect set of under seat speakers for their vehicle. These days, most vehicles come equipped with some sort of built-in amplifier or audio system.

And while this isn’t necessarily a bad thing, there’s still a chance that you may not be using these systems to their fullest potential.

The truth is, there are lots of things to consider before choosing the Best Under Seat Subwoofer with Built in Amplifier.


The RMS (Root Mean Square) is one of the most important figures when buying an amplifier. This figure tells you how loud a speaker can play. So, if you want to buy a cheap amp, you might be disappointed. However, if you want to spend more money, then you’re going to get better sound quality and power handling.

So, what does this mean? A low RMS value means that the speaker will not be able to produce a lot of volume. But, it will also have a lower peak power. This means that the speaker is less powerful.

On the contrary, a high RMS value means that you’ll be able to hear a lot of volume.


The sensitivity of your speakers is another thing that you need to pay attention to. Your best under seat subwoofer with built-in amplifier has to have a sensitivity rating of about 100.

That means that it can produce a maximum output of 100 watts. This means that it will be able to handle the maximum volume that you want to use. This is why it is important to check its sensitivity rating before you buy one.

The sensitivity rating of the speaker will indicate the volume level at which the speaker can produce sound without distortion. This also shows how loud the speaker can go before it becomes distorted. However, the higher the sensitivity rating, the louder the volume that the speaker can produce.


The frequency response refers to the frequency range that the speaker can handle. If the speaker has a wide frequency response, then it means that it can reproduce the entire range of frequencies.

If your speaker has a narrow frequency response, then it can only handle a small portion of the frequency spectrum. A speaker with a narrow frequency response can’t handle loud sounds very well. This is why it is important to choose a speaker with a wide frequency response.


is the measure of resistance to the flow of current. A speaker with low impedance means that it can handle high volume with ease. This is a good feature if you play the music that has a lot of bass or loud sounds.

It is recommended that you pick a speaker that has a low impedance to avoid distortion. High Impedance is bad because it limits the amount of power that the speaker can handle.


Surround is the thin material that covers the edge of the subwoofer cone. Its purpose is to prevent the cone from coming loose from its position, thereby absorbing any excessive pressure applied to it.

Rubber is the most popular material for surrounds today. Rubber has the advantage of being stiff and flexible at the same time, as well as resistant to heat and humidity. As a result, rubber surrounds last for years.

There are other alternatives to rubber, such as foam and cloth. While these are also stiff and flexible, they are not as durable as rubber. That is unless another material is mixed in to make them more resistant to extreme temperatures and humidity.


Subwoofers are very small speakers that produce bass frequencies by using cones, which are usually made of paper, plastic, glass fiber, wood, and metal. They come in various shapes such as round, rectangular, elliptical, etc. But, they all basically work on the same principle; that is to move air from one place to another.

So, a cone will vibrate when it moves through a medium. It will then change direction at its extreme points (where the vibrations stop). And the sound waves generated will be heard when these changed directions reach our ears.

For deep information watch the video:


Subwoofers can be made out of different materials. But, polypropylene is one of the most popular choices. Why? Because it’s very strong and durable. And, it also makes subwoofers lighter than other types of cones.

Polypropylene is a thermoplastic polymer that is used in many applications including medical devices, food packaging, automotive parts, clothing, toys, furniture, and more. This material is also commonly known as PP or propylene. So, if you want to build a subwoofer, then you can use polypropylene.

But, you should make sure that you choose the right size. For example, you should make sure that your cone is big enough for the volume of the bass you are trying to reproduce. If you don’t do this, you will end up having a lot of distortion. Also, you should make sure that the cone has the correct shape.

If you want to know more about building a subwoofer, you should read the article below.


The cone material for a subwoofer is an important part of its design. A cone is the main component that produces sound. There are two kinds of materials that can be used to make a cone.

The first one is wood. Wood is a very popular choice because it is easy to work with and is cheap to purchase. However, this type of cone is not suitable if you want to play music at high volumes.

Carbon fiber cones are a better option. This is because carbon fiber is stronger than wood and is also more durable. Therefore, these types of cones are often preferred by people who listen to loud music.

Another important factor when choosing a cone material is the size. Smaller cones are easier to handle and are less likely to break.


Cones are made out of plastic. They are very lightweight but they don’t last as long as other materials. A cone is usually used for low-frequency sounds. But, if you use it for a higher range, then you could damage the speaker.

Kevlar is a strong synthetic fiber that is often found in bulletproof vests. It’s also known as aramid. This is because it is derived from a plant called KEVLAR. It’s durable, flexible, and lightweight. However, it doesn’t absorb sound as cones do.

So, when you buy a subwoofer, make sure that you choose the right cone material and the right Kevlar.


When choosing a cone material, you need to pay attention to two things. First, you need to make sure that it is made from durable materials. Second, you need to make sure that it is treated.

The most lightweight cone material is treated paper. Therefore, it gives the quickest response time, which is the speed at which a cone can move back and forth in order to produce sound waves.

In contrast to regular paper, treated paper is coated with materials that make it durable against heat and humidity. These include carbon fiber, poly glass, and kevlar.


1. Are under-seat subwoofers any good?

Yes. Subwoofers are used in large venues to reduce the noise level. Some subwoofers are placed under a seat, or behind the stage, but others are used by a live sound engineer to create bass.

And yes these under seat subwoofers are good, but only for bass, not all sound. A subwoofer is a great tool for deep bass that can fill up large rooms, but most movies do not have deep bass content.

2. How thick should under seat car subwoofers be?

It is usually advisable to install an under seat subwoofer that is less than 3 inches thick. You can place it under either the driver’s or passenger’s seat for the best experience.

3. Does under seat subs need amplifier?

Yes, you do need a power amp for the car subwoofer. A powered sub will always sound better than one that is not. If you have two subwoofers or one sub with two channels, you can use one channel to act as a receiver for the other channel.

In contrast, powered car subwoofers already include an amplifier built in, and they are all packaged in one compact enclosure, so you don’t have to buy all the components separately. The amplifier and the subwoofer enclosure don’t have to be purchased separately if you like the subwoofer you like.

4. Where should underseat subwoofer be placed?

If you want to listen to a subwoofer, you need to place it behind you. So, if you sit on the front seat, you won’t be able to hear the bass effect well.

If you place it under the front seat, the speaker is facing the dashboard. And if you put it under the back seat, then you are facing backward. So, the right place for a subwoofer is under the driver’s seat.
