Showcasing the Best in the Mobile Enhancement Industry
If you’re talking with car audio enthusiasts, mention of the word decibel instantly fires up a conversation of how loudly an audio system will play. But that’s just one of the ways we use decibels to compare levels in audio systems. This article will dive deep into the options to express values using decibel scaling. What Is a Decibel? Forget everything you think you know Read more
In the fall of 2021, we took some detailed measurements to quantify the frequency response characteristics of several different RCA cables. These varied from solutions as simple as a pair of 18-AWG wires that were twisted together, to premium coaxial conductors and twisted-pair cables with extensive shielding. The results, as presented, showed negligible variations in response Read more
The confusion around setting amplifier gains baffles a significant number of car audio enthusiasts. I can’t even count the number of systems I’ve heard that are plagued with tons of background noise or hiss when music isn’t playing. Unfortunately, those same people also seem to be pretty hard on their gear and have replaced many subwoofers, speakers and tweeters. So let’s have Read more
When it comes to car audio subwoofer enclosures, the two most popular options are sealed or vented. As far as which design is best for your vehicle, let’s see if we can clear up some misconceptions and stereotypes. As often happens, some trade-offs accompany each decision.

It’s time we start putting together the information from a selection of the articles I’ve created to help sound quality enthusiasts get the most from their car audio systems. In this article, we will discuss why it might be best to choose a low-power, high-quality Class AB amplifier to power your tweeters. We’ll look at this from both a noise and distortion perspective, as well Read more
Quite a while back, I took a scientific look at the difference between a recording stored in a WAV format and what is thrown away with a lossy format like MP3. During some recent research in preparation for an upcoming Test Drive Review, I got to thinking about a different way to show how other audio formats compare. Let’s look at WAV, FLAC and MP3 file formats, then throw in a Read more
Not long ago, I wrote an article about fuses in car audio systems and some of the steps I took at a previous employer to test them. In part of that testing, I also dissected a few circuit breakers to learn how they worked and whether they were a good option as an overcurrent protection device in a car audio system. Immediately upon opening one, I was turned off. I remain so to Read more
So, as a longtime car audio guy, I have peers and friends who cover every conceivable genre of car audio enthusiasm. I have friends who are installers, own and run stores, work at distributors and at manufacturers. I have tweaky friends that think high-end interconnects and low-efficiency wideband drivers are the way to go for sound quality. I also have a ton of friends who are Read more
I remember being at a car audio trade show about a decade ago where I overheard a conversation between a manufacturer rep and a customer about why a set of tweeters didn’t sound good on a particular amplifier. A few weeks later, I did some research on that amp to begin learning about what might have produced the customer perception. The amp in question uses a Class D output Read more
