Showcasing the Best in the Mobile Enhancement Industry
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 very different ways. Let’s take a deep look Read more
AOver the decades, a question that’s come up thousands of times asks about the source of engine noise or alternator whine in car stereo systems. From the 1970s through today, every professional amplifier or signal processor installation finished with a test for unwanted noises. The cause of this whining or buzzing was often simple; however, technicians might have to spend Read more
Never in a million years did we think that the internet would debate the appropriate amount of time that’s ideal for a remote starter to warm up a car. Some folks believe that even a minute is too much, and others want the interior to be toasty and warm and are willing to let the vehicle idle for 15, 20 or even 30 minutes. Let’s talk about the physics of cold engine starting Read more
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 know we’ve challenged the status quo. Don’t worry; we can always Read more
In most car audio applications, dual voice coil subwoofers are typically wired in series or parallel to optimize an amplifier’s power production capabilities. In some cases, especially when an installation is performed with existing equipment, installers must get creative with voice coil wiring. Let’s look at a few unique solutions for optimizing the available amplifier Read more
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 a car audio Read more
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
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 bass. That’s fine, given the goals. The issue is how horrific the midbass Read more
AmsssssssPart Two of our series on the difference between car audio amplifiers will look at the topic of noise. Every amplifier, from every brand and at every price point, adds a little bit of noise to the audio signal that passes through it. Whether that noise is an issue depends on the amplifier’s design and the speakers you’re using. Let’s take a close look at noise and Read more
