If you look at some amateur car audio forums and Facebook groups, you’ll see a disturbing trend of people using speakers that are intended for home applications in their cars. While these speakers initially seem to offer impressive performance for their price, they simply aren’t designed to withstand the challenges associated with a mobile audio […]

Years ago, upgrading your car stereo meant buying a new radio that would play MP3 files or that included Bluetooth hands-free calling and audio streaming. As automobile manufacturers have increased their interest in providing advanced infotainment features, the aftermarket head unit industry has evolved away from conventional single- and double-DIN radios with segmented displays to […]

Nobody will deny that the Apple iPod is single-handedly responsible for a massive shift in the portability of music. Sure, the Walkman and Discman were important components in the history of portable media players, but those technologies supported existing music formats in the form of cassettes and compact discs. The iPod embraced digital media file […]

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 […]

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 […]
