Things to Consider While Buying a Car Subwoofer

Before you invest your money into a car subwoofer, there are several key features to consider, which are as follows:


The size of the subwoofer plays a crucial role in the overall sound quality. Generally, larger subwoofers produce deeper and more powerful bass. However, they also require more space and may not fit in all vehicles. Alternatively, smaller subwoofers are more compact and can fit in tight spaces, but they may not produce the same bass level as their larger counterparts.

Power Handling

A subwoofer’s power handling capacity determines how much power it can handle without distorting or getting damaged. Make sure to match the power handling capacity of your subwoofer with your amplifier’s output to avoid any damage.


The sensitivity of a subwoofer determines how loud it can get with a certain amount of power. A higher sensitivity rating means that the subwoofer can produce more sound with less power.

Voice Coil Configuration

Subwoofers can come with a single voice coil or multiple voice coils. A single voice coil is easier to install and is more affordable, while a multiple voice coil subwoofer provides more wiring flexibility and allows for higher power handling.

Enclosure Type

The enclosure type of a subwoofer can affect the overall sound quality. A sealed enclosure provides a more accurate and tight bass response, while a ported enclosure produces more deep and louder bass.


Choosing the best car subwoofer can be a daunting task, but considering some key features can make the process easier. There are numerous car subwoofers available out there. However, the MTX Audio Terminator series is considered the best one. Still, it’s recommended to consider your needs and preferences while selecting a car subwoofer!

Closing FAQS About Car Subwoofers

Can I Install A Subwoofer In My Car Myself?

Yes, you can install a subwoofer in your car yourself. However, it is important to note that installing a subwoofer requires some technical knowledge and skill, so if you are not confident in your ability to do it yourself; it may be best to seek the help of a professional.

How Much Power Should My Subwoofer Be Able To Handle?

The power handling capacity of a subwoofer depends on various factors, such as the size of the subwoofer, the type of music you listen to, and your personal preferences. As a general rule, a 12-inch subwoofer will need 150 to 1000 watts to produce good sound.

Can I Use A Subwoofer Without An Amplifier?

Yes, you can use a subwoofer without an amplifier if it is an active subwoofer. Active subwoofers come with built-in amplification circuits that allow them to drive low frequencies without the need for an external amp. However, if you have a passive subwoofer, then you will need to connect it to an amplifier or receiver in order to power it.
