Best 8-inch Subwoofer

While the world is getting smaller and smaller and we now live in a global village, there is still a disconnect when it comes to music. We listen to music when we wake up and we listen to music at the end of the day as we fall asleep.

It helps us relax and unwind as we go about our daily lives. The only problem is that most of us don’t have the right kind of systems to play great music. Subwoofers are the most underrated component of any home theater system. 

An 8-inch subwoofer is a speaker that is usually installed in a car. It is capable of producing the main part of the bass sound in the car. The sound produced by an 8-inch subwoofer is not as loud as those produced by the 10-inch and 12-inch ones.

An 8-inch subwoofer is available with a frequency of between 30 and 200 Hz. In this article, we’ll rank the 4 best 8-inch subwoofers by customer reviews, price, and performance.

Pyle Car Subwoofer Audio Speaker

The Pyle Car Subwoofer Audio Speaker has an output of 400 watts RMS and an output of 800 watts. The sensitivity is 89 dB, it features a two-piece impedance of 4 ohms and a four-piece voice coil with 1.5-inch resistance to corrosion for longer life.

The surrounding area is coated with foam for durability while the 3.7-inch installation depth is suitable for most automobiles, RVs, and boats. This subwoofer is perfect if you have a budget and limited room in your car.

While it won’t blow your car’s roof, it sounds great with a suitable enclosure. The dual voice spiral also allows you to obtain 2 ohms if your amplifier is a 2 ohms device.

While the subwoofer is quite expensive and provides respectable bass notes, nonetheless, hard, low punches are not handled. It does not work well at a high volume, too. You will hear some distortion if turning the volume too high.

Things that Should be Kept in Mind while Purchasing the Subwoofer

It all comes down to personal preference and how loud and deep you like your bass, but for those who are new to vehicle audio and subwoofers in particular, here are a few pointers and things to keep an eye out for when selecting the best 8-inch subwoofer for you.

Car, truck, and other vehicle subwoofers are available in a variety of sizes ranging from 8 to 15 inches. Generally speaking, larger subwoofers produce stronger bass, but this is not always the case in practice.

Additionally, there are several other parameters that influence performance, including the sensitivity rating, the enclosure type, and power handling capabilities.

An 8-inch subwoofer is frequently superior to a factory-installed subwoofer, particularly if it is configured for maximum performance.

Type of Enclosure

This is a crucial characteristic because it has an impact on the overall sound quality of the subwoofer. The manner in which the sub is encased can also have an impact on performance.

For example, the finest 8-inch subwoofer for a sealed box will produce the deepest bass, whilst the best subwoofers for a ported enclosure and bandpass enclosure will allow for higher levels of loudness.

Frequency Range

A subwoofer is limited in terms of the frequency range that it can produce and reproduce. A subwoofer with a lower frequency limit that is smaller will create deeper and lower frequencies.

If you want truly deep bass, seek a subwoofer with the lowest frequency limit possible. In most cases, a high-power 8-inch subwoofer will have a lower frequency rating, often between 20 and 30 hertz.

Single Vs. Dual Voice

Using a single voice coil can be advantageous if you want to make a quick and easy modification to your audio system. When it comes to increasing the number of sound outputs, dual voice coils provide greater flexibility.

Consider two voice coils if you prefer modifying your stereo system to get the greatest sound possible.


Every subwoofer has a wattage rating, which indicates how much power it is capable of delivering. The fact that this rating is for peak performance should be kept in mind.

A subwoofer that continues to work at its maximum capacity for a lengthy period of time will eventually overheat and fail to function properly. If you want to know how much power the sub can take regularly, look at the root mean square (RMS).

Rating of Suspensibility

In order to establish how strong a subwoofer is, it is necessary to consider both the sensitivity value and the power rating.

Comparing the two subwoofers, the sub with the higher sensitivity is capable of producing the same level of sound with less power as the sub with the lower sensitivity.


Does a subwoofer need an amp? 

A powerful subwoofer is usually equipped with an enclosure speaker as well as an amplifier. A tiny vehicle with little space for a separate speaker and amplifier configuration is an excellent choice.

Does the material of the subwoofer cone make a difference?  

Subwoofer cones are made of a variety of materials, ranging from paper to synthetics to composites. Paper is less durable than other materials, yet it is lightweight and responds quickly. In general, most varieties of material function perfectly well and produce similarly excellent sound quality.


Are you looking for the best 8-inch subwoofer but don’t know how to pick one? A subwoofer is an integral part of your car audio system. It is the one that provides the bass in your music.

If you are not satisfied with the bass in your music then you need to get a good subwoofer. A good subwoofer will not just increase the bass but also give you an enhanced sound quality. If you are looking for one then this blog is for you.
