Showcasing the Best in the Mobile Enhancement Industry
Who wouldn’t want to buy the loudest, most efficient speaker possible to upgrade their car audio system? A speaker that does a better job converting electrical energy into sound reduces the load on the vehicle’s electrical system, right? Well, efficiency is just a single parameter in the myriad values that describe how a speaker works. Let’s take a super-techy look at how Read more
Decades ago, it took about $40 in parts, on top of the cost of a new car radio, to give yourself improved sound quality and more features. A simple wire harness adapter would let a single-DIN radio connect right to the factory radio harness behind your dash. Add an antenna adapter and you were likely on your way.Fast-forward to the 2020s and modern infotainment systems Read more
I recently had a discussion with several industry peers on Facebook about the correlation between audio component measurements and how that translates into subjective listening evaluations. Respectfully, I’m always astonished by the number of people who think distortion measurements don’t directly correlate to perceived product quality. The Science of Car Audio Component Read more
A while back, we took a close look at the harmonic distortion performance of a 6.5-inch door speaker from a Honda Civic. We measured the Theile/Small parameters and the driver’s impedance curve. Next, we looked at how much distortion the speaker created at different drive levels. If you haven’t read that article, it’s a bit of a prerequisite for this one. You can find it here: Read more
If there’s a single marketing statement that makes my eye twitch, it’s one that claims a specific subwoofer will “work” in a small enclosure. Contrary to many marketing claims, enclosure volume is directly proportional to low-frequency extension and sound quality. Let’s look at the math and how these tiny enclosures ruin the performance of your subwoofer. The Backstory on Read more
I can’t even begin to count the number of times I’ve seen car audio speakers installed improperly in the doors, dash or rear deck of a car or truck. Many amateur car audio enthusiasts don’t understand that unlike home audio and Bluetooth speakers that come in an enclosure, the way that raw speakers are mounted in your vehicle plays a huge role in what they’ll sound like. Let’s Read more
Somewhere around ninth grade, most high school students in North America learn about Ohm’s law in science class. Despite repeated efforts and claims to debunk the laws of physics, Ohm’s law remains a constant that car audio enthusiasts and professionals deal with every day. On a related subject, I see questions about speaker and amplifier wire sizing all the time. To help Read more
You’d think it’d be easy to choose an amplifier of a specific power rating to work with a 500-watt subwoofer. In reality, we need to consider several factors, particularly performance and reliability. Let’s take a detailed look at the complexity of choosing the perfect amplifier for your car audio subwoofer system. The Myth and Mystery of Car Audio Amplifier Power Read more
For as long as I can remember, car radios have had their “maximum power” ratings all over their packaging and often right on the face of the radio. These numbers are not only useless in terms of an ability to reproduce music with any sense of quality, but I have always questioned whether they are even possible. Let’s measure how much power a conventional car audio head unit can Read more
