Showcasing the Best in the Mobile Enhancement Industry
After a recent vehicle introduction, discussions about vehicles with 48-volt electrical systems are at an all-time high. Changing standards in vehicles is nothing new. Most cars manufactured before the mid-1950s came with 6-volt batteries. As the need for power and speed from various automobile components has increased, we’re about to witness a change to 48-volt systems. Let’s Read more
It is said that simplicity is the ultimate sophistication, and sometimes this point cannot be argued. We really loved the Honda CR-V Hybrid for being a quality SUV offering just the right amount of size, space and fuel economy. Everything has been engineered with Honda purpose for ease of use and reliability. Boasting 37 mpg overall without the need to plug it in, it should be Read more
Professional technicians have several options available to analyze audio signals. We can use an oscilloscope to look at the amplitude of a signal in the time domain. We can use a real-time audio analyzer to look at signals in the frequency domain. Thanks to the power of modern computers, we can combine both measurements to create a spectrogram to look at audio amplitude and Read more
Every genre of car audio enthusiast looks at amplifier performance differently. The SQ guys worry about distortion and noise. The bass heads focus on power. The keyboard commandos and know-it-alls talk about slew rate or something equally irrelevant. Despite all this, an audio system's frequency response matters the most regarding the perception of quality. The folks at KICKER Read more
The BestCarAudio.com team received a great question about subwoofer polarity and how a crossover affected the phase at the crossover point. Specifically, the question focused on whether the subwoofer polarity needed to be reversed if the sub amp used a -12 dB/octave filter. The short answer is yes. As always happens with audio systems, the full answer isn’t as simple once we Read more
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 words refer to Read more
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 those that Read more
Any time your installer wants to wire two subwoofers to the same channel of an amplifier, they can wire them in series or parallel. The same goes for a dual voice coil design subwoofer. The only benefit of a DVC subwoofer over a single is that there are three wiring options. We examined whether the wiring options for dual voice coil subwoofers differed a while back. Thinking Read more
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 series of articles on understanding subwoofer Read more
