At least once a week, someone comments on social media or in a forum that you can’t hear low-frequency distortion from subwoofers or amplifiers. We have no idea where this myth came from. However, if you understand what distortion is and how it works, you’ll know this myth is utter and complete nonsense. Yes, we […]

Fine-Tuning Your Sound: Understanding the Power of Parametric Equalizers
When looking at the options for frequency response correction for audio systems, your installer has two choices: graphic or parametric equalizers. Both types of equalizers perform the same task in helping to smooth the peaks and dips in what you hear from your audio system. However, the two equalizer types deliver the same results in […]
Why Is a Car Audio Equalizer Important to Create Realistic Sound?
The single most crucial upgrade a person can make to their car audio system is to incorporate a properly configured equalizer. Whether you have a radio and two speakers or a high-end four-way system with active crossovers, ensuring that the system’s frequency response is accurate remains the most important consideration concerning quality. Let’s examine how […]
Car Audio Amplifier Remote Level Controls Aren’t Universal
Here are three sentences that make car audio experts cringe: “I set the gains halfway” is definitely at the top of the list. “Can I use a 60-watt amp with my 80-watt speakers?” demonstrates a complete misunderstanding of the irrelevance of power ratings. Something like “I tried the remote bass control from my Sony amp […]
Tips for a Loud Car Stereo System: It’s Speaker Excursion, Not Efficiency
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. We’ve lost track of how many of these vehicles we’ve heard that sound utterly atrocious. No, we aren’t talking about the fact there’s 30 or 40 dB too much […]
Selecting the Best Amplifier for Your Car Audio Speakers
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 […]
Explaining Audio Signal Phase and Polarity
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 […]
Explaining The Class SB Car Audio Amplifier
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 […]
Under-Seat Truck Subwoofers – Face Up or Down?
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 […]
Why Do Speakers and Subwoofers Sometimes Have CCAW Voice Coils?
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 […]
