Let’s face it, most of us aren’t really happy with the stereo system that comes in our car. Sure, if you bought a Lexus with a top-of-the-line Mark Levinson system, you’re more than likely content. For the rest of us, the good news is that for a very reasonable investment, you can upgrade the performance […]

In the ’80s, ’90s and early part of the 2000s, upgrading the car stereo system in your vehicle was a relatively simple process. You’d start by picking out a new radio that offered the features you wanted and add a set of speakers to improve the sound of the system. Pretty much anyone with a […]

Not too long ago, we saw a discussion about an article called “The 12 Best Tweeters (Reviews & Ultimate Buying Guide 2018).” Being curious, we decided to check the article out to see what criteria they used to choose the products and how they tested them. Much to our dismay, there were no criteria, nor […]

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 […]
