Car Subwoofers - Car Subs

Have you heard about car subwoofers and curious to learn what one is? Well a subwoofer is a speaker that is not it in a box and powered by an amplifier that is tuned in to and plays back low-frequency sound or bass. Subwoofers create low-frequency sounds and contain those several octaves that are missing from most car stereo systems. They enjoy heavy use in urban areas with certain types of underground music. There is even a whole genre of music designed to subwoofers and low-frequency modulation

playback in mind. The genre is known as "the bass track".

Not Every Car Subwoofer Is Created Equal:

Subwoofers are either passive or powered, with the passive systems drawing power off of the regular audio system, and the powered systems have an independent powerline hooked up to them. Car subwoofers are mounted in boxes and placed in the trunks of the automobiles, or in other places such as the space beneath the car's rear window. Car subwoofers also vary in size, on average from 6.5 inches all the way up to 60 inches in the very large monster subwoofer category. There are relatively inexpensive subwoofers that are available, however the car subwoofer is somewhat of a luxury item to begin with, so don't expect to get off cheap.

The Typical Car Subwoofer Setup:

The car subwoofer is mounted in a box of some sort, although some of them come in tubes. Each of them has their own amplifier hooked up to the speaker that comprises subwoofer. Independent amplification is necessary, because of the nature of the output strength. Since the car subwoofer has to be mounted in a box, they can take up a lot of room. For the most part, is definitely a given that you will have to sacrifice a substantial amount of space in order to house this specialty item. There are systems these days as well that place the car subwoofer and unused nooks and crannies of the car.
