Do I Need A Subwoofer In My Car? (Pros & Cons)

Do I Need A Subwoofer In My Car

Do you need a subwoofer in your car? If you like to listen to quality music with deep bass, then yes! A subwoofer would be an excellent addition. This will be able to crank out those low-end frequencies with efficiency, accuracy, and high-quality sound, allowing you to feel your music while driving.

However, if you prefer a more subtle and accurate sound and only want the bass when it’s called for in the song, then no. You can get away with just using your factory speakers or adding a set of aftermarket speakers that have some sort of built-in amplifier.

Subwoofers are also great for letting you hear the details in your favorite music that may have otherwise gone unnoticed. If you find yourself turning up the volume of your music to listen to the bass while driving, then investing in a subwoofer would be worth the money.

This blog post will explain what a subwoofer does and why people install them in their cars.  

Does A Subwoofer Make A Difference In A Car?

Yes, a subwoofer is a decent sound technology that can make a whole lot of difference in your car. It would improve our car’s sound system and make it sound better.

The system dynamics of your vehicle rocks better with a subwoofer. Rather than upgrading your electronics, getting subwoofers for cars would offer you excellent efficiency. 

Benefits 


There are various benefits that you can access by using subwoofers for cars. They include: 

Sound without Distortion 

A subwoofer minimizes distortion by lessening the acoustic demands that are placed on your other speakers. Using a complete range and quality speaker reproduces high-quality bass of low-frequency with the large cone and diaphragm that causes distortion. 

If you prefer to listen to your music at high volumes, there’s a high chance that the woofers of your audio speakers cannot handle it. With a subwoofer, you can listen to loud music without dealing with distortions, especially when the music is filled with plenty of basses. 

Improved Clarity 

The regular speakers in your car can only produce music to a certain extent. A quality subwoofer improves the quality of sound you hear by reproducing even the fastest basslines with preciseness. 

It is crucial to be aware while choosing a subwoofer because a subwoofer of low quality cannot deal with vocal stops and rapid starts. Also, some instrumentals are peculiar to specific genres of music that require a quality subwoofer for effective production. With inferior subs, you would have to deal with a faint acoustic sound. 

Increased Bass Response 

Subwoofers are essential significantly because they increase the bass response of the sound you hear. They serve as an expansion of the bass response to produce a loud sound that your regular speakers cannot make out. Most cars use speakers that drop off at 50Hz, but subwoofers produce lower frequencies up to 20Hz. 

You can immerse yourself in music with a subwoofer knowing that you would never miss the lowest notes. It produces the full depth of the music alongside bass clarity. 

Relieves Smaller Speakers 

Small speakers struggle to reproduce exceedingly low-frequency sounds. You can relieve your small speakers to make sounds that fall within a comfortable range. 

Subwoofers help lighten the weight of full-range speakers by enhancing the performance. It reproduces quality sound with bass and clarity without distortion. You get to reduce the workload of your smaller speakers by purchasing a subwoofer for your car. It gives you actual sound at a higher level by focusing on a non-directional sound that you can both feel and hear. 

Offers Full Spectrum Response 

You can use a quality subwoofer as an extension of your full-spectrum speakers. Your speakers can offer their best performance with a subwoofer because they can cut across the frequency spectrum, whether mid or high frequencies. Your sound systems will function more effectively with sub. 

Your car stereo speakers can perform at their peak by combining a quality subwoofer with proper bass management, a low-frequency amplifier, and a connected AV receiver.

Regardless of the type of music you are listening to, you get its precise sounds. You can prevent yourself from missing out on the fullness of the musicians’ sounds to entertain you. 

Disadvantages 


As I’ve established that using a subwoofer is a matter of choice. It is only necessary to identify the disadvantages and why some car owners believe that getting a subwoofer is unnecessary. 

Disturbance 

A subwoofer can be a significant disturbance because of the loudness of the sounds that it produces. It can disturb a peaceful atmosphere and make too much noise, especially on the road where most people are trying to get to their destination. Subwoofers are powerful machines that can divert your attention from driving, especially in crowded spaces. 

Weight

Subwoofers are naturally heavy, which makes them difficult to carry. Their large size subwoofer also makes them take up a whole lot of space in the car. This is why you have to consider your car size before you get a subwoofer, so you determine whether there is enough room for the sound system or not. 

Installation 

The installation process is complex, and you would require a professional to help you with audio engineering, especially if it is your first time. Getting a professional means sparing extra cash to get the job done. It can seem like a waste of time if you are not particular about purchasing a subwoofer to improve sound quality.

Power Supply

One of the most significant challenges of using a subwoofer is the power supply. A subwoofer consumes more power because of its high wattage compared to audio transducers. You have to confirm if the head unit of your car can support a subwoofer channel.

It might require that you buy another head unit or a mono-block amplifier to install the speaker properly. 

Cost 

Subwoofers are priced between $75 to $150, and you would have to incur extra costs to install them. To successfully set up a quality subwoofer, your average budget should be about $200 to get it to work perfectly. You would also have to purchase other accessories to ensure that the sound comes out correctly. 


Do Subwoofers Mess Up Your Car?

Subwoofers cannot cause any mechanical damage to your car. However, there are certain areas where it can affect our vehicle. 

Stresses Body Panels 

It can stress your body panels due to the constant vibration. The mounting bolts and plastic tabs of your car can come undone due to the frequency of the vibration. Also, the door panels, rearview mirror, and other nuts can be loosened because they are exposed to vibrational waves. 

Causes Rattling 

A subwoofer can cause your car to rattle. It means that parts of your car can start shaking or vibrating against each other.

This problem is more prominent for vehicles with poor soundproofing that can protect them from the vibration of subwoofers. You can prevent all the damages caused by the constant vibration of the subwoofer when you make your car soundproof.

Makes Car Rear Sag 

Due to the weight of subwoofers, your car’s rear can begin to sag. When you get a big subwoofer, it can exert much pressure, especially on small cars causing it to sag badly. This can cause essential parts of your car to drag on the road and damage them. 

Will Having A Subwoofer In My Car Kill My Alternator Or Battery?

Not necessarily. A subwoofer can kill your battery when the power output is more than what it gets from the alternator. Your car battery dies when it is not charged enough while using a subwoofer.

A subwoofer is an additional load for your electrical system, drawing more power from your car battery. It requires additional current to make out the bass frequency that a subwoofer produces. 

Subwoofers have no direct effect on your alternator. However, when a subwoofer is used with an amplifier, the amplifier can draw too much current from your battery which can cause overheating for your alternator. When the alternator overheats continuously, it eventually dies.

Make sure to get a high output alternator that receives the needed current without affecting the car’s electronics.

What Size Of Subwoofers Do I Need For My Car? 

Choosing the right size subwoofer can be pretty confusing for most people. They aren’t sure what sizes they need to look for or what subwoofer is best suited for their vehicle. There are so many options out there, and the size is not always indicative of how much bass you can get.

Here we attempt to give you some idea of what sizes of subwoofers you should consider for your car.

Firstly, you need to ask yourself, “what is my budget?” and “how big is the subwoofer enclosure I have available for my subwoofer”. Would you rather pay a little more money and have a large subwoofer for your car, or is it better to go for something smaller that will allow you to save some money?

Secondly, when you are planning on having your subwoofers installed. Do not forget to take into account the available space you will have in your car. This will help your installer to choose the correct size of subwoofer that you need.

For example, if you’re driving a small car, it is unreasonable to get a heavy subwoofer because it would take too much space and slow down the function of your vehicle. Only get a big subwoofer for a car that is spacious enough to contain it without any complications.

Lastly, do not forget to consider how much power you plan to have your subwoofer amplifier give to these subwoofers. 


Final Thoughts

Jamming some hot music while going for a road trip is a delightful listening experience that you can trade for a bit of stress and money. A subwoofer can help you have a wonderful time with your friends right in the comfort of your car without having to get into a club.
