Significance of Subwoofers


Who doesn’t love to hear music while driving? Having a good subwoofer will make the difference. It can make the music that you listen to in your car take center stage. The difference between having a good subwoofer is huge. The subwoofer will expand the range of your car’s sound system. When you add a subwoofer, you get that extra bass in your car audio system. The music sound better than never, thanks to the low frequencies that the subwoofer produces.

Subwoofer Frequencies

Subwoofer frequencies have a range that can go as low as 10Hz or as high as 1000Hz. Do keeping in mind that subwoofers with very low frequencies are no longer audible by the human ear. Therefore, it is a waste of money getting a subwoofer with a frequency that’s lower than 10Hz. Subwoofers with higher frequencies give a car’s audio system a full depth of sounds and can transform your audio experience in a unique and awesome one.

Sizing Subwoofers

With subwoofers, size matters. The bigger the subs, the better bass are produced. Also, the size of the subwoofer that is perfect for you will depend on the type of car that you own. It will not make sense getting a sub that is too big or too small for your vehicle.


Subwoofers have different sizes. Their sizes range from 8 inches to 15 inches. In order to operate correctly, a subwoofer should be mounted to a subwoofer box. The smallest subwoofers 8 to 10 inches can add more depth to your car, and it is needed a less box volume. If your vehicle falls into the category of SUVs, mid-size sedans or hatchbacks, you should consider this type of subs.

But do keep in mind that these types of subwoofers don’t produce bass as good as the 12 and 15-inch subwoofers. If your vehicle fall in the category of pickup trucks, luxury sedans or full sized SUVs and you are a fan of loud noises and the “boomy” sound, then you are better off with a 12-inch subwoofer in the market today.You will be able to feel your car rattle because the sound produced will be stronger than the smaller-sized subwoofers.

However, if you are in the market for a subwoofer that will produce an excellent bass and a massive quantity of sound, then you should invest in the best 15-inch subwoofer in the market today. These types of subs are custom-sized subs, and they are set based on competition because these subs enhance performance and loudness. These types of subs are only made by customization. They are so big in size that some decisions have to be taken into account.

What is the type of vehicle that you have and how are you going to put these subs in are just a few things that you need to look into before you opt to buy a 15-inch subwoofer. Saying this, the bigger the subs, the bigger the boxes will be and of course, the bigger the vehicle that you will need to have.

Car Subwoofers Are Not Created Equal


There are only two types of subwoofers that can be made: a powered type and a passive type. The powered type subwoofers have a built-in amplifier and are fed by a low-level signal passed along an interconnecting cable. Whereas the passive type which is the majority of speakers doesn’t have a built-in amplifier, so it needs to be connected to an amplifier through a normal speaker wire.

This means that it takes power from the car audio itself and this is also the reason why when installing a subwoofer, they are in a suitable box and a suitable place inside the car.

How Do I Set My Subwoofers Up?

The placement, the positioning, the connectivity, and fine-tuning are the important things to consider when you will be setting a subwoofer up. And because a sub can take a lot of space in the vehicle, you have to be prepared to lose some space to gain better sound. It is also important to know if the set-ups for subwoofers are placed in boxes or a mounted tube format.

Usually, the sub will be connected to an amplifier to deliver power through the audio system. You must have a good knowledge in installing subs if you want to do it yourself otherwise, your subwoofers will not function properly. If necessary watch a video first about setting up a subwoofer or get an expert to do the job.

Subwoofer Spending

First of all, you have to decide on how much you want and can realistically spend on a subwoofer for your car. After making this decision, find the best in your price range and buy it. You can find great bargains online if you want to save a few dollars while getting the best option available.


Moreover, even if you have the right budget for your car subwoofer, you have to keep in mind these two important things: the size of the sub and the space that you have in the vehicle where you are going to install it. The size of the sub will affect the size of the box, and that can make a difference, not only on your vehicle space but also on your budget. Don’t use the rule of thumb. Always use and follow your common sense.
