Showcasing the Best in the Mobile Enhancement Industry
Some of the most common car audio questions on social media are about finding a good ground location for an amplifier. Thinking about the topic, using the term ground to describe the negative power connection to the amplifier might imply it’s not as important as the positive battery connection. Both connections must be equally capable of passing all the current the amplifier Read more
Social media conversations are often a great source of content ideas here at BestCarAudio.com. We were recently talking to someone about why loading down an amplifier isn’t an ideal solution. As we’ve demonstrated in our Test Drive Reviews, lower impedances result in more distortion in most cases. In all cases, lower impedance loads reduce amplifier efficiency. Let’s discuss Read more
As we continue our series on what makes one amplifier sound different from another, we will look at intermodulation distortion. As you should know by now, harmonic distortion creates higher frequency components that can make an audio device sound harsh or bright. Intermodulation distortion is typically responsible for unwanted warmth or sloppiness in lower frequencies. When Read more
Listening to a genuinely high-end home or car audio system can be amazing. For those who care about sound quality, several technical considerations separate a very good audio system from one that’s truly magnificent. These might be beyond what most strive for in their car audio upgrade. With that said, if your goal is a genuinely realistic music experience, these are Read more
For as long as I can remember, the ubiquitous ground loop isolator has been a staple of the car audio industry. In recent years, the need for these noise-elimination devices has decreased dramatically, thanks to the inclusion of balanced or differential input circuits on amplifiers or signal processors. Let’s dissect an isolator and make a few measurements to see how adding one Read more
As we continue to explain what makes one amplifier different from another, we’ll look at distortion in the context of power level and frequency. Unbeknown to most enthusiasts, how an amplifier behaves varies based on the frequency you ask it to play and how much power it produces. The latter is a crucial piece of information if you’re looking for an amplifier that will sound Read more
Can you imagine if the inch or centimeter weren’t measurement standards? Nobody would be able to describe the size of anything. Standards are all around us. Distance, time and temperature descriptions are things we take for granted. Why, then, shouldn’t measurements of car audio components have measurement standards? Fortunately, they do, but you’ll still find many companies Read more
When most people think of Rockford Fosgate, they remember that this brand has been delivering car audio products that enthusiasts have craved for over 50 years. Rockford Fosgate’s experience has made them a leader in the development of high-performance amplifiers, speakers and, of course, car audio subwoofers. Rockford has a truly incomparable solution for those who are truly Read more
We just escaped from one of the most confusing car audio conversations ever. In a social media group dedicated to measuring the harmonic distortion characteristics of amplifiers, a member challenged the importance or validity of the topic. We can’t imagine having that much spare time. OK, well, maybe that’s appropriate in a flat earth group. Anyway, let’s talk about a few Read more
We’re back to bust another car audio myth wide open. This article will discuss the myth that DVC subwoofers can handle more power than a single voice coil driver. After some research, it’s clear that consumers seem to think dual voice coil (DVC) subwoofers have the equivalent of two separate voice coil assemblies, allowing them to handle twice as much power as an SVC design. Read more
A Over the decades, a question that’s come up thousands of times asks about the source of engine noise or alternator whine in car stereo systems. From the 1970s through today, every professional amplifier or signal processor installation finished with a test for unwanted noises. The cause of this whining or buzzing was often simple; however, technicians might have to spend Read more
We had the opportunity to check out Sony’s Mobile ES monoblock XM-1ES, four-channel XM-4ES and five-channel XM-5ES amplifiers in 2022. All three amps performed well on the test bench and in our listening room. For 2023, Sony has introduced two new amplifiers: the eight-channel XM-8ES and the six-channel XM-6ES. Let’s dive into the XM-8ES in this BestCarAudio.com Test Drive Read more
