Buyer’s Guide

If you’re looking to get yourself a subwoofer for your car, then you need to keep a few key aspects in mind while doing so. There are a wide variety of woofers available in the market that serve different tastes and requirements, and it is essential to understand the features of this woofer before you make a purchase. SO to help you with choosing the right subwoofer for your car’s audio system, we have included a small guide that will discuss the various aspect of subwoofers in order to help you find what exactly you’re looking for.

  1. Size of the subwoofer – This is a critical element that you should look out for a while purchasing a subwoofer. Car subwoofers come in a wide range of sizes that can be anything between 8 inches all the way to 15 inches. The size of the woofer you purchase should always depend on how loud you want the bass to be and how much your car space is. The larger the woofer, the louder the base but the sweet spot lies within the range of 8-12 inches for car audio systems.
  2. Power – If you want a woofer that is very boomy and produces loud bass that rattles up anything your car passes by, then you should look for a woofer with plenty of power. Take a look at the RMS Power Rating and the Peak Power rating of the woofers as they are a suitable indicator of how powerful the bass can be. It is also important to match the woofer’s power handling to the amplifier’s power output.
  3. Frequency Range – The frequency range of a subwoofer gives an idea of how well the woofer can play the low frequencies. The smaller the value of the lower end of the frequency range, the better the woofer will be at reproducing bass. However, it is essential to keep in mind that the actual performance of a sub is also dependent on other factors such as the enclosure and the box type it has been mounted in.
  4. Sensitivity – The sensitivity value of a woofer is just as important as the Power rating when it comes to knowing how powerful a woofer is. A higher sensitivity means the woofer can produce the same amount of sound with a lower requirement of power when compared to a woofer with a lower sensitivity.
  5. Number of Voice Coils – Dual Voice Coil subwoofers are the most popular choice when it comes to car subwoofers as is allows for greater flexibility while working sound systems. Typical subwoofers feature just one voice coil while the dual voice coil variant has two separate loops, each with their own connections that are mounted on a cylinder.
  6. Enclosure Type – The enclosure on which a subwoofer is mounted on can impact the performance of a subwoofer to a large extent. Sealed boxes give the deepest bass while the ported and bandpass enclosures provide more volume.


So hopefully we have been able to help you out with choosing a great subwoofer for your car. All the best 8 inch subwoofers reviewed in the article are great choices if you’re looking to upgrade your car’s audio system and get yourself a booming woofer that shakes up every neighborhood you ride onto.
