Amplifier Differences, Part 5: Intermodulation Distortion

As we continue our series on what makes one amplifier sound different from another, we will look at intermodulation distortion. As you should know by now, harmonic distortion creates higher frequency components that can make an audio device sound harsh or bright. Intermodulation distortion is typically responsible for unwanted warmth or sloppiness in lower frequencies. When Read more

The Four Stages of High-End Car Audio – Frequency Response

Listening to a genuinely high-end home or car audio system can be amazing. For those who care about sound quality, several technical considerations separate a very good audio system from one that’s truly magnificent.

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 in my Rockford Fosgate amp” couldn’t be scarier. Can you Read more

The Automotive Future – 48-Volt Electrical Systems

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

What Is a Spectrogram and Why Are They Useful?

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

Test Drive Review: KICKER KEY200.4 Smart Amplifier

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

Question of the Month: Main Speaker to Subwoofer Polarity

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
