Showcasing the Best in the Mobile Enhancement Industry
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
We talked about headlight bulb styles in the first part of our series on understanding headlight upgrades. In this article, we will briefly explain relevant light terminology to help you understand what lumens, lux, candela and watts mean. Knowing what these terms mean will help you make better bulb upgrade choices – and you’ll be less likely to be fooled by bogus light output Read more
It should go without saying that a car stereo system designed around multiple amplifier channels and a DSP is the easiest way to get great sound in your vehicle. The technician working on your vehicle has complete control over the output level, sound arrival time and the frequency response of each speaker in the system. The result should be a sound system that is as optimized Read more
We’ve talked at length about how car audio line output converters work and have even compared a few to see which sound best. We skipped over a discussion on whether a car audio amplifier upgrade needs a line-output converter. Let’s dive in! What Does a Line Output Converter Do? A high-quality line output converter serves three purposes. First and foremost, it can reduce the Read more
