Why replace your old stereo with an 8-inch subwoofer?

It is important to understand why 8-inch subwoofers are the choice of many and what pros are attached to them;

8-inch speakers are battery efficient

Sound lovers try to avoid placing big-size subwoofers in their cars due to battery drainage. It would not be wrong to say that the bigger size subwoofers consume an ample amount of battery, due to which the power of the battery is not transmitted to other important components of the car.

However, the best 8 inch subwoofer does not consume much battery because of its typically small size yet provides amazing sound quality that will surely revitalize your driving experience altogether.

Accurate bass – not more nor less – just perfect!

If you are an avid music enthusiast, you would hate your factory-installed stereo system. As a stereo system is not a car’s operating essential, many manufacturers don’t pay much attention. Therefore, the sound quality of the pre-installed audio system is not effective. Moreover, getting a quality stereo is pricey, which stops many from getting a better sound system.

However, in this scenario, the audio companies came up with much more budget-friendly solutions to this problem. With 8-inch stereo subwoofers, not only have they made a quality sound system available for the masses, that has perfect bass and clear output but at affordable pricing as well.

Five-channel amplifier friendly

Bigger size subwoofers such as a 10-inch or 15-inch, require a separate amplifier or a dedicated monoblock amp. However, an 8-inch subwoofer easily connects with a five-channel amplifier that is available in most cars. You will not have to pay extra bucks for a separate amplifier to listen to quality music with accurate bass.

Protects your factory’s speaker

Many people are not satisfied with the sound quality their factory-installed speakers are providing. Sometimes they listen to songs on such a high volume that it damages the stereo system entirely as these speakers are not manufactured in a way that can tolerate that much bass.

However, the entire scenario changes with an 8-inch subwoofer. A complete load of bass and extra sound is transferred to the subwoofer, which keeps the factory’s speaker protected.

Key features in an 8-inch subwoofer?

While you are all set to purchase an 8-inch subwoofer, try to look upon the key aspects of it. It is important to understand the factors which are necessary for a great quality subwoofer. Let’s discuss the key features;


Subwoofers are available for cars to trucks ranging from 8” to 15” inches. Many people have a perception that the size of a subwoofer determines its sound quality and bass. However, it is somewhat right but not entirely.

There are other features of a subwoofer as well which are interlinked to its quality. Nevertheless, it is great to have an 8-inch subwoofer placed in your car instead of the factory-installed speakers. To improve the sound quality, the tiniest subwoofer is the ideal choice for you.

Enclosure type

It is important to understand that closeness of sub to the enclosure will surely have an impact on the performance of a subwoofer. If an 8-inch subwoofer is packed in a sealed box, it generates the deepest base which is desired by many sound lovers.

On the other hand, if an 8-inch subwoofer is found in the bandpass and a ported enclosure, it will create a large sound volume.

Single vs Dual voice coils

If you just wish to upgrade your sound system with basic means so the single voice coil is considered ideal for you. However, if you wish to add some other components, later on, the dual voice coils are the right choice for you.

Well, for the customization purpose, dual voice coils are considered perfect for your car.

Frequency range

The frequency of the game is different in every subwoofer. If you have placed a smaller lower limit subwoofer, it would produce lower and deeper frequencies. People who wish to listen to the deepest base should look for a subwoofer with the lowest frequency.

An 8-inch subwoofer will have a lower frequency between 20 to 30 hertz.


You would not find any subwoofer in the market that would be available without its signature wattage rating. There is a sufficient power supply which a subwoofer can handle and does not get disrupted. The major reason for the right amount of power is the performance of the subwoofer. If the power supply is not up to the mark, the sound quality would be affected.

On the other hand, if the subwoofer is operating or running continuously on the higher rating, there are relatively chances for it to face overheating problems and might fail later on. Your main focus should be on the root mean square (RMS) to check exactly how much power the subwoofer can handle.

Sensitivity rating

After understanding the real concept of power wattage in a subwoofer, your attention should be towards the second most important thing in this component which is sensitivity. If you own a subwoofer that is high insensitivity, it can run on low power yet producing an impeccable sound experience. This way you’ll be saving good units of electricity if you are using it in your homes or your car’s battery if using it in your vehicle.
