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 […]

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 […]

Undoubtedly, you’ve heard the term GPS. It’s not uncommon for consumers to refer to navigation software like Waze, Google Maps, Apple Maps or a portable navigation device from Garmin or TomTom as a GPS. Unfortunately, giving these solutions the GPS title is incorrect. Let’s look at GPS, how it works, and how similar technologies are […]
