Car audio source unit manufacturers are constantly developing new products to fill the gaps between entry-level and flagship models. Sony recently released a new 2-DIN digital multimedia receiver called the XAV-AX3700, which slides into the mix just below the XAV-AX4000. This new radio features a 6.95-inch touchscreen display, Apple CarPlay connectivity and iDatalink Maestro vehicle […]
We aren’t sure where or when things went wrong with the basshead crowd, but there’s a serious misunderstanding about how to build a loud stereo system.

There’s nonsense about subwoofer cone materials improving sound quality, claims that Class D can’t sound better than Class AB, or that remote car starters are bad for your vehicle. This article will be the first in a series that addresses […]
Speaker power ratings are among the most confusing and misleading specifications in the car audio industry. Once you understand the process used to test speaker power handling, you’ll quickly realize that the information doesn’t always translate to information that’s helpful in choosing an amplifier. Let’s dive into the science behind choosing the best amplifier for […]
Understanding how DC voltages combine is quite simple. They add linearly when we wire sources (like batteries) in series. But understanding how AC waveforms combine is complicated. AC waveforms don’t always sum intuitively unless the peaks and valleys align perfectly. We see many examples where people interchange the terms phase and polarity. In reality, those […]
There will always be debates about whether a Class D amplifier can sound as good as a Class AB. We’ve proven that it all depends on who designs the amplifier. We also see mumblings about single-ended amps versus full-bridge designs. STMicroelectronics created a different and unexpected way to deliver efficient power. These amplifiers are categorized […]
Floating-face car radios are popular because of their flexible installation options and relatively massive displays. The Sony team has been hard at work updating their products, and the new 10.1-inch XAV-AX8500 digital multimedia receiver is their latest offering in this hot market segment.
