When it comes to speakers, size matters. Similarly, when purchasing a subwoofer, you may be advised to consider the size of the unit to purchase. Since this type of speaker is specifically designed to reproduce the lowest 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 you plan to fit that speaker in in your car. The key is to make measurements on the size, space and purpose in which the speakers are supposed to be used. However, size and space aren’t the only things to measure 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 ranges of bass and notes. 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 their 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, higher resistance values or ohm levels mean higher resistance to current flow at which the speaker operates, and lower values mean lower resistance to current flow. A typical subwoofer may be rated from 4 to 8 ohms. Values can be as low as 2 ohms and as high as 30 or more ohms. When you intend to connect the speaker to a sound system, pay attention to its ohm rating to ensure it meets the specific electrical requirements of the system.
In a typical sound system, many receiver components, such as speakers, do not function 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 the speakers require surely affects the quality of the sound it reproduces. 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, ohm levels present a challenge for someone who must combine multiple speakers on one channel, as you need careful calculations on the resistance levels of your circuit. Disregarding the ohm ratings of the subwoofers or not following the precise application specifications for the subwoofers can be detrimental if it is connected to a system that is not designed to work with it.
In a car audio system, the subwoofer speakers are just as important as for other car sound system components. It is essential for playing high-quality low notes. 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 seriously poor sound quality, as well as damage to the electrical circuits that operate the other components of your car’s audio system.
