Showcasing the Best in the Mobile Enhancement Industry
A while back, I published an article that compared a high-quality Class-D amplifier with a low-quality “internet-brand” Class AB amp to prove a point about topology not being the deciding factor in performance and accuracy. The contrast in their performance was shocking, with the Class-D amp besting the AB in every way. An amateur YouTuber made a video breaking down the Read more
Efficiency is defined as the ratio of the power or work consumed by a system compared to the work done by that system. In the car audio industry, we typically talk about efficiency in the context of amplifiers. The best amplifiers consume only a little more power than they provide to a speaker or subwoofer. Low-quality solutions consume extra power and convert that into heat. I Read more
I can’t count the number of times I’ve seen enthusiasts and folks in the car audio industry claim that Class AB amplifiers are better for high-frequency (as opposed to subwoofer) duties than a Class D design. I recently had a chance to put a popular new Class AB amp through its paces on the BestCarAudio.com Test Bench, and the results were surprising. Let’s make a quality 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
While it’s fun to play with flagship products like Audison Thesis amplifiers and speakers, the reality is that there’s a lot more business done at the opposite end of the financial spectrum. The latest generation of the SR line from Audison gives car audio enthusiasts an affordable upgrade option that is laden with the features found in much more expensive solutions. For this Read more
It seems like everything to do with car audio installations has something to do with managing voltages. For starters, your electrical system needs to produce enough voltage to keep your radio and amplifier going. And amplifiers need to increase the voltage to drive speakers. When adding an amplifier to a factory-installed audio system, your installer will need to measure the Read more
When it comes to expressing the quality of an audio system component, the amount of distortion it adds to a signal is the defining factor. In this article, we’ll talk about how much distortion each part of an audio system adds – so that you can target your budget for the greatest benefit. We’ll rank four categories of audio equipment based on the amount of distortion they add Read more
A while back, we took a quick look at how alternating current (AC) signals in our car audio systems work. While the amount of work done by an AC voltage source can be the same as that of a direct current (DC) source, the changes in current flow direction add complications. In this article, we’ll dive a little deeper into AC signals and explain why a fixed-value resistor can’t Read more
For car audio enthusiasts, especially those interested in competing in SPL competitions, amplifier efficiency should be one of their primary concerns. In this first of three articles on efficiency, we take a close look at the Rockford Fosgate M5-1000X1 Class-D subwoofer amp and analyze how well it makes use of power at different output levels. What Is Car Audio Subwoofer Amp Read more
