How to Choose the Best Subwoofer for Your Car
There are a few different factors you may have to consider before investing in a subwoofer for your car. This is not a decision you can come to without at least some deliberation, especially for those of you who are big on road trips and enjoying good music while on the road.
With a good subwoofer, the music listening experience while you are on the road is elevated to another level. Once you find that sweet spot, it will be hard for you to go back. So to avoid disappointments and hits and trials, consider at least the following factors when looking for a subwoofer for your car:
Mounting a Subwoofer in Your Vehicle
How is the subwoofer mounted? Depending on the kind of space you have in your car or in your truck, the mounting will have to be adjusted accordingly.
For example, if you have a spatial constraint, which is likely with a sedan or with a smaller car, you may prefer an under seat mounting. This occupies as little space as possible while also lending your car bass. This is a neat way of taking care of the installation. A compact subwoofer can also be installed in the hatch or the trunk of your car.
Another way of mounting the sub is to shallow mount it. A shallow-mount subwoofer is also a relatively compact variety of sub. It is lightweight and easily portable. It can be installed in the trunk and the rear speaker deck. It is different from a larger speaker as the quality of sound is bound to differ, but if space constraint is your problem, an under seat mounting or shallow mounting is the best option.
Larger speakers have regular mounting, but this is ideal only for a larger vehicle and may perhaps not be feasible for a smaller car or sedan.
Size – 10 Inch VS 12 Inch Car Subwoofers
The size of the subwoofer makes a world of a difference. There are two main sizes that you may come across in the market — 10-inch and 12-inch car subwoofers. The list above has also included eight-inch subs which tend to be the compact variety for those who are especially strapped for space.
If you only want to install a subwoofer in your car to enjoy some music while you are on the road, either of the two main varieties should suffice, depending on your budget and the kind of space you have. But for audiophiles, the difference in the sound quality might be too stark.
In a 12-inch sub, since there is more cone area, more sound can resonate off the cone and create a deeper bass. The larger the cone area, the greater the chance that the unit can play the lower frequencies better. But while on paper it seems like the 12-inch sub provides better sound, a lot depends on the quality of the manufacturing and the frequency range.
The 10-inch subwoofers do seem to be more responsive as well. But in the end, the decision you make about the size also depends on the kind of space you have and the budget you are willing to set. For example, if you drive a small hatchback or even a coupé like the Volkswagen Beetle, a larger subwoofer would be of no help to you. You would be better off with a smaller size, perhaps even a compact eight-inch sub.
So pick the size of your subwoofer accordingly, based on how much space you have and what kind of bass you are looking for.
Installation of Car Subs
Any car subwoofer should be easy to install, either as a DIY or by a paid professional if you are unsure of the process. Most require an amplifier wiring kit. If you invest in a car subwoofer package, chances are you will get the whole kit along with the main subwoofer. Often, these are better deals as you can get these packages at a discount.
Most also come along with an enclosure, often made of cast aluminum, which is meant to keep the amplifier cool and prevent it from overheating. If the subwoofer does not come with an enclosure, you will need to purchase one separately in order to install it in your car.
All in all, the steps involved in installing a subwoofer can be complex for a novice so if you are unsure, it is best to pay a professional to complete the installation for you. If you want to try and DIY your sub installation, here is a handy guide to installing the subwoofers in your car.
Enhance Your Musical Journey
If you have a long journey ahead, the road is made only more fun with the right kind of music. Often certain albums or songs become iconic in your memory simply because you enjoyed listening to it on an open road.
But you will be unable to make these memories if you do not have a good sound system, and no sound system is complete without a good subwoofer.
Hitting the low notes is important in any good musical composition and if your woofer cannot emanate the low frequencies correctly, it can diminish the fun of a good road trip and of a good piece of music. So choose wisely and enjoy the tunes!
