Car Subwoofer Sizes

Here are the most common subwoofer sizes and who are they for. We all know the bigger the better but there’s a limit to it as well.


8-inch Car Subwoofers


The smallest available option in car subwoofers is 8”. This type of subwoofer is typically found in factory-installed sound systems for cars. If you have a small car and limited space, this is the right choice for you.

One of the best things about 8-inch subs is that they are usually easy to install because of their small size.

The drawback with 8-inch subs is that they are not capable of producing a lot of bass. Some people even consider it to be a drawback because 8-inch subs do not have the ability to reproduce very low frequencies.


10-inch Car Subwoofers


A 10-inch subwoofer is an excellent purchase for smaller cars because it does not take up a lot of space. 10-inch subwoofers can produce a lot more bass than their smaller counterparts. This means that you will get the most out of the music that you listen to while driving on the highway.

They are not only easy to install but also they provide good value for your money because they are not very expensive.

10-inch subs can be a good choice if you want a replacement for the factory installed subwoofer or if you have a medium size car. If you are looking for an inexpensive way to upgrade your sound system, then this is the best solution that you can consider.


12-inch Car Subwoofer


12-inch subwoofers are one of the most popular choice for car audio enthusiasts. They are not only powerful but also provide superior sound quality compared to the other smaller car subwoofers.

The good thing about 12-inch subs is that they can reproduce very low frequencies, which means you will have an excellent listening experience when driving on the highway or cruising around with your friends.

These subs are not only efficient but also perfect for larger cars because of their large size. If your car has a big trunk area where you can fit in a 12” subwoofer, then this is definitely worth considering. It is important to buy these types of subs from reputable manufacturers so that you can get both high performance and great value for your money.


15-inch Car Subwoofer


15-inch subs are almost the largest subwoofers that you can find in the market. They are ideal for larger cars where there is enough space to accommodate them. If you have a large car, then these subs will produce excellent sound quality and are also one of the best options if you are looking for great bass.

These subwoofers offer maximum power compared to all other sizes. If you have a large car with an empty trunk, then this is definitely one of the best choices available to you right now.

The downside with 15-inch subs is that they are expensive and difficult to install because they require a lot of space, which might not be possible in smaller cars.

If your car has limited space or does not have enough room for these subwoofers, then it is better to look at something more practical like 10-inch types instead of spending money on larger subwoofers that will take up too much space.

That being said, buying 15” subs from reputable manufacturers means that you can get great value for your money.


18-inch Subwoofers


18-inch subwoofers are the largest type of car subwoofers available in the market. Even though they can take up a lot of space, these types of subwoofers come with their own benefits. For example, there is enough room to accommodate high-level bass reproduction which means you will enjoy excellent sound quality.

The best thing about 18” subs is that they can produce very low frequencies, which is perfect for people who enjoy listening to their music at really high volumes.

18-inch subwoofers are not only powerful but also provide superior sound quality compared to the other smaller car subwoofers.

If you have a large vehicle with adequate space, then these types of subwoofers are worth considering because they produce excellent bass and will give you an immersive experience when driving down the road. However, if you do not have enough room for them in your car, then it is better to look at something more practical like 12” subs instead of spending money on larger subwoofers that will take up too much space.

The main drawback with these types of subwoofers is that they are very expensive and difficult to install because they require extra space inside your car.

For most people , 10-inch and 12-inch subwoofers are the best, as they are affordable and can deliver decent sound quality. If you like listening to music at higher volumes, then 15” subwoofers are the perfect choice because they will give you the best performance overall.
