Showcasing the Best in the Mobile Enhancement Industry
Car audio upgrades are much more complex than setting up speakers in your living room. They are, unless all you have in the system is a set of coaxial speakers in your doors. Your installer has to consider crossover slopes and alignments if you have front and rear speakers and a subwoofer. They must also understand how the settings interact at the crossover frequency. Let’s Read more
We’ve watched hundreds of videos on YouTube and read dozens of articles on headlight upgrades, yet we’ve never seen anybody discuss how different bulb types light up different colored objects. We aren’t discussing the headlight bulbs’ brightness or the beam pattern. Halogen, HID and LED bulbs output different wavelengths of energy. We see objects when that energy reflects off Read more
If there’s one thing that’s challenging for car audio manufacturers and retailers, it’s explaining the sonic benefits of higher-quality products. Based on our research, many consumers correlate the word “better” with more power production from an amplifier, more power handling from a speaker, or more features from a source unit. While these statements are often accurate, they Read more
Let’s take a look at amplifier, speaker and subwoofer quality. This time, it won’t be a series of lab measurements that evaluate distortion, frequency response or power. It won’t even include listening evaluations or comments on shiny products.Many years ago, Rockford Fosgate ran a magazine advertisement showing a picture of a Punch 75 HD amplifier and Bruce. Bruce is Read more
Last year, we published a series of articles that compared several 6.5-inch woofers. Those articles were intended to show the linearity and distortion differences between entry-level products and those with features that improve performance and sound quality. The results were exactly as we expected: The better drivers played louder with less distortion. We figured it was about Read more
A short while ago, we published an article examining the resistance of different wire-to-wire electrical connection methods. We tested everything from twisting the wires to soldering, crimp connections, and even some popular connections for residential applications. Aside from the solder sleeve connection’s performance, nothing surprised us. Let’s dig into what worked, what Read more
We are back with the third article in our series about headlight bulb upgrades. In the first article, we discussed the many different headlight bulb designs and how they’ve advanced over the last century. The second article in the series explained the terminology used when discussing light sources. How a light assembly projects light onto the road is more important than the Read more
There’s a common belief that an audio system with more subwoofers will produce more bass. This statement can be 100% true or completely false. Why might it be false? A subwoofer’s output depends heavily on enclosure design. Let’s look at two examples where the output of one subwoofer is more than two. The Most Bass for Your Dollar If you spend any time searching the countless Read more
A while back, we looked at how adding stuffing to a sealed enclosure affects its performance. It was clear from our measurements that the addition of Dacron lowered the system’s Qtc (Total Q). The original theory was that adding stuffing made the enclosure seem larger and let the driver play louder at low frequencies. Let’s revisit this test and add several acoustic Read more
