About Car Subwoofers
Car subwoofers are large speakers that are used to create frequencies that ordinary loudspeakers are unable to produce effectively. These frequencies are usually in the range at or below 100Hz. These subwoofers are typically 8 inches or larger, and have to be placed in an enclosure to function properly.

Types
-
There are several types of car subwoofers: tube-type subwoofers and vehicle-specific subwoofers. The tube-type car subwoofer contains the subwoofer on one end and is sealed on the other. Vehicle-specific subwoofers are built primarily from wood and fiberglass. They are designed to fit into "factory-created" pocket. These tend to be more specific than the tube-type due to the fact that they are specific to one vehicle.
Considerations
-
Car subwoofers tend to take up quite a bit of space because of their size. Anyone considering the purchase of a subwoofer must take the space factor into consideration before buying one. The smaller the space within which to place a subwoofer, the more the power of the subwoofer will have to be increased.

Features
-
Features of car subwoofers include enclosure type, power handling and sensitivity. The enclosure is basically the kind of box the actual subwoofer will be mounted in. The power handling is the amount of power the speaker can withstand before failure becomes imminent. Sensitivity is a measure of a specific amount of the subwoofer's power at a certain distance. The standard car subwoofer sensitivity is 1 watt of power to 1 meter of distance.
Misconceptions
-
Generally speaking, one 12-inch car subwoofer will be more powerful than two 10-inch subwoofers. There are a number of factors that need to be taken into consideration when making this choice, but for the most part, one larger subwoofer will have more clarity and more punch than two smaller ones.
Function
-
Car subwoofer cones are made of treated paper or composites. Paper is too lightweight to withstand the power of the subwoofer for extended periods of time, but it also tends to be more responsive. To achieve a "big bass" sound, increase the number of car subwoofers. The greater the cone surface area, the greater the sound.
