Car Subwoofers – How Do They Work?

Executive Summary by Bishara Hazboun

Car Subwoofers are widely used by car owners and fans. Car Subwoofers are loudspeakers intended to generate the lowest frequencies, or bass end of the audible sound range.

Car Subwoofer Speakers

Because car subwoofers are specialized reproducers, their design maximizes their potential for generating the lowest frequency. Middle frequencies have smaller cones and less excursion, or cone travel.

Car Subwoofer cones must move in and out with the longest possible extension because sound waves get longer as they get lower in frequency. The cone works as a piston to compress and alternatively evacuate large masses of air.

What Effect Does the Number of Ohms Have When Choosing a Car Subwoofer?
Executive Summary by Jay Rivett

When it comes to speakers, size matters. Car audio enthusiasts have long grown passion in finding the best subwoofer speakers that they can install in their SPL war cars.

For both SPL competition and ordinary car sound systems, one important point that must be considered when choosing a subwoofer speaker is its wiring or sound system application specifications. More importantly, pay attention to its ohm ratings.

Ohm levels or ohm ratings refer to the measurement of resistance to the flow or electricity or current within a circuit. In the case of subwoofer speakers, high resistance values or ohm levels means greater resistance to the flow of current in which the speaker operates and lower values means less resistance to current flow. A typical subwoofer may have a 4 to 8 ohm rating. The values may go as low as 2 ohms and as high as 30 or more ohms. When you intend to have the speaker wired into a sound system, pay attention to its ohm values to make sure that it meets the specific electrical requirements of the system.

In a typical sound system, many receiver components, such as the speakers, do not work properly when it handles ohm levels that are beyond its operating specifications. Having actual circuit resistance or ohm values that are lower or higher than what the speakers require surely affects the quality of sound that it reproduces.

In a car audio system, subwoofer speakers are equally important as to other in-car sound system components. It is essential to reproducing high-quality low base notes.
