When it comes to speakers, size matters. Similarly, when shopping for a subwoofer, you may be advised to consider the size of the unit you should purchase. Since this type of speaker is specifically designed to reproduce the lower range of audible sound frequencies, the size of the woofers takes into account the range of bass sounds and notes that it can reproduce. Also, consider the space in which you plan to fit that speaker in your car. The key is to make measurements about the size, space, and purpose the speakers are supposed to be used for. However, size and space aren’t the only things to consider when choosing the best subwoofer for your sound system applications. You should also measure the amount of circuit current resistance or power impedance that the subwoofer requires to operate. Therefore, it is important to consider the ohm ratings of a subwoofer.
Car audio enthusiasts have long been passionate about finding the best subwoofer speakers to install in their SPL war cars. They are always on the lookout for the most powerful subwoofer speakers they can find, complementing their existing car audio systems by delivering the lowest possible bass and note ranges. For both competitive SPL and common car sound systems, an important point to consider when choosing a subwoofer is its wiring or sound system application specifications. More importantly, pay attention to your ohm ratings.
Ohm levels or ohm ratings refer to the measurement of resistance to flow or electricity or current within a circuit. In the case of subwoofers, high resistance values or ohm levels mean higher resistance to current flow that the speaker operates at and lower values mean lower resistance to current flow. A typical subwoofer might be rated from 4 to 8 ohms. Values can be as low as 2 ohms and as high as 30 ohms or more. When you intend to connect the speaker to a sound system, pay attention to its ohm ratings to ensure it meets the system’s specific electrical requirements.
In a typical sound system, many receiver components, such as speakers, do not perform properly when driving ohm levels that are beyond their operating specifications. Having actual circuit resistance or ohm values that are lower or higher than what your speakers require surely affects the quality of sound you reproduce. Factors that can affect the current impedance in the system into which the subwoofers can be connected include the use of improper types of amplifiers and other receiving devices. Therefore, the ohm levels present a challenge for someone who must combine multiple speakers into one channel, as he needs careful calculations on the resistance levels of his circuit. Failure to consider the ohm ratings of the subwoofers or following the precise application specifications of the subwoofers can be detrimental if connected to a system that is not designed to work with it.
In a car audio system, subwoofer speakers are just as important as for other components of the car’s sound system. It is essential for playing low notes of high quality. To be reliable in this regard, it has electrical wiring and application specifications that must be followed. Neglect or failure to follow and understand these specifications can result in very poor sound quality, as well as damage to the electrical circuits that operate the other components of your car’s audio system.
