Best 6.5 Inch Subwoofers: Buying Guide

Before investing in a 6.5-inch sub:

  1. Decide what you exactly want from it.
  2. Before making a purchase, take measurements of the available space.
  3. Decide where you want to place your subwoofer and then make a purchase according to it. 

There is no doubt that a good subwoofer can make your vehicle’s sounding system from drab to fab. So there are things that should be taken into account before you purchase your subwoofer. 

Available Space
We mentioned this before, but we are stressing over it again as the amount of available space should be considered before anything else. Subwoofers are three-dimensional, and they are not going to lay flat.

So get yourself a measuring tool and begin to analyze the space that you can accord to the subwoofer. Consider the amount of mounting depth that will be required for it. Take care of every measurement and then move on to the next step; find a subwoofer according to the space available.
Single or Pair?
Most subwoofers are available as single pieces while others come in pairs. It is highly likely that a single piece will not be enough for most people. So before making a purchase, check if the price you’re paying is meant for a pair or a single piece. Then, decide if you want more than 2 pieces for a fully bass boosted system and place your order accordingly.
Mounting or no mounting?
Most of the subwoofers will require mounting as they are built without an enclosure. So you can have some fun building an enclosure for your subwoofer or buy a mounting bracket.

A few subwoofers do not need an enclosure, and they are designed to work just fine without it. Most people find such subwoofers more convenient, however, getting a mounting bracket for your subwoofer isn’t much of a task. Just keep it as simple as possible!
Weather Proofing
This feature is not necessary, but if you’re purchasing a subwoofer for ruggedized use all year round then, it is better to choose the one that is weather resistant. The Kicker CompRT in our list is a weatherproof option. It can stand rain and other challenging weather types. So if you are looking for an outdoor subwoofer, this has to be the one.
Material Type
Subwoofers are available in a variety of material types. The best 6.5-inch subwoofers, in our opinion, are those manufactured with paper, silk, or silicone cones. They are good for high-frequency sounds.

The best material for surrounds is rubber, while foam and cloth can also work well. The copper or aluminium coils should be sturdy, and the overall material of the subwoofer should be stiff to withstand powerful performances.
Power Rating
Always check the RMS rating of the subwoofer before buying it, for it will determine its compatibility with your amplifier. A higher RMS value means that the subwoofer can handle more power.

The RMS value determines the amount of power that is continuously used by the woofer. The maximum or peak power of most subwoofers is also mentioned. So don’t forget to check the RMS value no matter what.
A subwoofer is installed directly into the vehicle, so it needs to be a durable device. Not only that, it should be future proof to an extent as well so it can be compatible with any future vehicle stereo system. 
Also, it has to stand the vibration and all the thumps due to the bass, so heavy-duty housing and construction are necessary for longer durability.
There is a wide range of options for subwoofers available in the market within different price ranges. If you’re looking for affordable options, you can get some decent subwoofers within 20 to 50 dollars.

However, if you are a serious audiophile, you can find some great options within 60 to 150 dollars. We have added options to our list considering all these price ranges. You can easily choose any of them according to your requirement.
Before purchasing a 6.5-inch subwoofer, give a good thought to the functions that you want from it. Don’t buy just for the sake of getting a subwoofer. Deicide what you actually need and then make a selection based on your budget.

It is not sane to waste those extra bucks on a subwoofer with high-end functions which are useless for you. If you will not use a subwoofer’s ‘so and so’ function, then why do you think you should pay for it? So don’t resort to overbuying and make a wise decision according to your needs.

6.5-inch subs are the best option for upgrading the stereo system of any vehicle. They are easy to install with no elaborate modifications required. Always buy from manufacturers with good customer reviews and don’t compromise on the quality of a few pennies. We are happy to assist you in choosing the best 6.5-inch subwoofer, and we hope that you have found the right one from our favourite picks!
