Safely Using Your Smartphone in Your Car
In 1982, Michael Knight was able to talk to his 1982 Pontiac Firebird and ask it for navigation directions. Of course, watching “Knight Rider” meant that we understood that KITT was make-believe. Fast-forward 35 years, and talking to our vehicles is now a reality, thanks to our smartphone. The modern smartphone, be it an iPhone […]
Be Wary of Top 10 Lists
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 […]
Car Audio Electrical Theory – Capacitance and Inductance
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 […]
Car Audio Electrical Theory – Magnetic Fields
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 […]
New Apple CarPlay Navigation Options
On Sept. 17, 2018, Apple launched iOS12 – its latest update to the operating system behind its venerable iPhone and iPad devices. Aside from security updates, performance enhancements and battery life improvements, Apple has added support for third-party applications to CarPlay. Users of factory-installed and aftermarket multimedia receivers that support CarPlay will now be able […]
Car Audio Electrical Theory – Amplitude and Frequency in AC Signals
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 […]
Car Audio Electrical Theory – An Introduction to Alternating Current
In our ongoing series of articles about car audio electrical theory, we are going to introduce the concept of alternating current power sources and signals. Understanding the basics of AC is crucial to understanding how a mobile audio system works. This article uses a lot of references to the electricity delivery systems used in our […]
