The Benefits of Subwoofer Speakers

March 27, 2012

In theory, you could do without subwoofer speakers, but the audio experience would be thin. Learn the basics of subwoofer speaker system installation.

Subwoofer Speaker

A key piece of car sound system is the choice of car stereo subwoofer speakers. Answer the following questions and you will find the system you need. Once installed into your car, then you should notice a huge difference in sound quality, and when you play your favorite tracks you will enjoy them that much more.

Determine the Size of the Available Space
Looking at average size of today's car, it is far smaller than the cars of even a decade ago. It is a task to find the space for a subwoofer speaker system. To determine the space available in your vehicle, look in the trunk area, the most recommended installation spot and doors. The amount of space available in either site will determine the size of the subwoofer.

In a small sedan, you will likely find the most available space directly under the rear package shelf at the rear window. This spot will take advantage of any available cross-member that can support the subwoofer and its enclosure. You may also find space on either side of the trunk, at the sides, or, if you have some luck, in the area of the spare tire under the flooring, where it can also take advantage of the spare tire wheel well.

Choose the Size of the Subwoofer Speakers
Your subwoofer speakers serve only one purpose in car sound, to enhance the low-frequency sound range of the music. Given today's smaller available installation space, the subwoofers should be large enough to enhance the low-frequency sound, yet small enough to fit into the available space.

Choose an Enclosure
The enclosure not only protects the subwoofer, it enhances the sound response by channeling the sound and reducing vibration. Pick one that fits both the subwoofer and the space snugly.

Select a Compatible Amplifier
The subwoofer must be amplified to produce the low-end response you are. The subwoofer amp is necessary because the bass or low-end response must be consistent. It does not have to be 400-watt monster amplifier because a small amplifier is more than enough to enhance response. An 18-watt, 4- to 8-ohm amplifier will probably do the job for you.

4 Common Subwoofer Installation Mistakes

When you install a subwoofer in your vehicle, take the time to complete the operation properly. If you don't familiarize yourself with the car stereo wiring and how to set up the car stereo amp along with the subwoofer there are a number of problems that may come up. Among them are the possibility of the subwoofer not working, the subwoofer actually being blown out and permanently damaged, and more. To avoid these potentially costly and frustrating disturbances, follow these tips when you're hooking up your car stereo to a subwoofer.

  • Leaving out the amp. The amplifier for your subwoofer is one of the critical parts of the system. It requires an amplifier in order to receive power properly from the head unit and the car battery. Without an amp, the subwoofer will not be properly regulated and you won't be able to control the levels of power that flow through to it. This can cause a host of other potential problems. Be sure to hook up the subwoofer to the amp properly.
  • Mistaking channels on the amp. Another problem is the subwoofer is connected to the amp in an incorrect way. The result is the subwoofer does not properly receive power. You should always re-channel the existing speakers through the amp so that the subwoofers can be powered out of the back end instead of the front.
  • Not shutting off power. One of the more dangerous mistakes that you can make when installing your subwoofer onto the stereo system in your car is to not turn off the power at the source. You should always disconnect the battery in the proper manner before you work on the electrical wiring for your car stereo or for any other part of the car. This will avoid electrocution and also the unnecessary and unwanted flow of power to certain parts of the car system that may not be prepared to handle it.
  • Improper mounting. Be sure to mount the subwoofer into the enclosure and the box properly, or else you may end up with rattling sounds or a loose subwoofer that can be easily damaged.
