Showcasing the Best in the Mobile Enhancement Industry
Car audio Amp power ratings are often the least important aspect in differentiating amplifier options. Sure, it matters whether you buy a 500- or 1,500-watt amplifier. Neither number tells you anything about either amplifier’s quality, performance or reliability. Surprisingly, many companies are still slapping inaccurate and often impossible power ratings on their products. We Read more
So far, we’ve demonstrated five easily measurable criteria that separate the performance of one amplifier from another. Some of these, like frequency response, can be compensated for using an equalizer. Others, like harmonic and intermodulation distortion, are permanently baked into the amplifier’s sonic signature. Does the amp sound clean and transparent, or does it color the Read more
Sometimes, it’s fun to poke at certain stereotypes in the audio community. Those who consider themselves audiophiles are often the easiest to harass as they frequently fall prey to crazy marketing stories sprinkled with just enough technical words to make them sound plausible. Do your speaker cables need acrylic spacers to keep them off the floor? Should you paint the edge of Read more
Some of the most common car audio questions on social media are about finding a good ground location for an amplifier. Thinking about the topic, using the term ground to describe the negative power connection to the amplifier might imply it’s not as important as the positive battery connection. Both connections must be equally capable of passing all the current the amplifier Read more
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
For as long as I can remember, the ubiquitous ground loop isolator has been a staple of the car audio industry. In recent years, the need for these noise-elimination devices has decreased dramatically, thanks to the inclusion of balanced or differential input circuits on amplifiers or signal processors. Let’s dissect an isolator and make a few measurements to see how adding one Read more
As we continue to explain what makes one amplifier different from another, we’ll look at distortion in the context of power level and frequency. Unbeknown to most enthusiasts, how an amplifier behaves varies based on the frequency you ask it to play and how much power it produces. The latter is a crucial piece of information if you’re looking for an amplifier that will sound Read more
Can you imagine if the inch or centimeter weren’t measurement standards? Nobody would be able to describe the size of anything. Standards are all around us. Distance, time and temperature descriptions are things we take for granted. Why, then, shouldn’t measurements of car audio components have measurement standards? Fortunately, they do, but you’ll still find many companies Read more
We just escaped from one of the most confusing car audio conversations ever. In a social media group dedicated to measuring the harmonic distortion characteristics of amplifiers, a member challenged the importance or validity of the topic. We can’t imagine having that much spare time. OK, well, maybe that’s appropriate in a flat earth group. Anyway, let’s talk about a few Read more
