When the temperature outside drops, it’s common for car and truck owners to want to warm their vehicles before driving off. Unfortunately, thieves know this is a great time of the year to steal vehicles idling in driveways and parking lots. Let’s look at how a remote car starter can make it safe and convenient […]
There isn’t a category in the mobile enhancement industry not plagued by myths and misunderstandings. 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. Let’s see what’s been added to the platform to keep it at […]
Over the last decade, the popularity of under-seat truck subwoofer upgrades has exploded. At least a dozen companies offer vehicle-specific solutions with shallow-mount subwoofers to add bass to these vehicles. If you’re perusing the enclosure options for your truck, you’ll notice two distinct options: enclosures with drivers that face upward into the seat bottom and […]
You should be aware that copper-clad aluminum wire is the least-preferred option for connecting an amplifier to your vehicle’s battery or alternator. Copper-clad aluminum wire has more resistance for a given diameter than an all-copper cable. As a result, it wastes precious voltage and transforms it into heat when it could be allowing your amplifier […]
What happens when a subwoofer is used with an oversized subwoofer enclosure? This article will look at the good, the bad and the ugly in terms of an improper match between the electromechanical characteristics of a subwoofer and the need for a proper enclosure. Why Do Subwoofers Need an Enclosure? If you’ve been following our […]
