As we move toward the end of our discussion of car audio electrical theory, we need to talk about capacitance and inductance and how the characteristics of those phenomena interact with AC and DC signals. There’s no doubt that these are advanced concepts, but even a basic understanding of how capacitors and inductors work is […]

Furthering our discussion about car audio electrical theory brings us to a discussion of how the flow of electricity through a conductor creates magnetic fields around the conductor. Understanding the relationship between current flow and magnetism is crucial to understanding how a speaker works. History of Electromagnetism The first documented correlation between electricity and magnetism […]

In our ongoing discussion of car audio electrical theory, we need to discuss some of the characteristics of alternating current signals. These points of discussion include the concept of amplitude and frequency. Understanding the concept of frequency is crucial to developing an understanding of how the components in our audio systems work. The Concept of […]

For several years, the Best Car Audio team has provided articles on the features, functions and benefits of all manner of car audio products and services. Well into our third year, it’s time to go back to the basics and talk about the fundamental theories of electricity and how they relate to our car audio […]

In any discussion about understanding sound, the unit of decibels will undoubtedly become part of the conversation. Unlike almost all other units of measurement, the decibel is not a linear scale. That is to say, 1 decibel (also written as dB) is not one-tenth the amplitude or strength of 10dB. In this article, we’ll explain […]

There is nothing worse than turning up your music only to hear your car speakers or subwoofers rattle and buzz because they are damaged. Well, there is something worse: You could turn up the volume and hear nothing at all. We hear stories about people damaging their car speakers all the time. In almost every […]
