Showcasing the Best in the Mobile Enhancement Industry
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
Rockford Fosgate, a brand synonymous with Harley-Davidson amplifier, speaker and subwoofer upgrades, has just introduced its PMX-HD14 multimedia infotainment system. If you have a 2014 and newer Street Glide or Ultra, or 2015 and newer Road Glide, this might be the perfect way to make your entire stereo system sound better. Best of all, it’s got a unique trick up its sleeve. Read more
The 2023 Ford Raptor R is a certified beast. The specifications are incredible. The 5.2-liter supercharged V8 is pilfered from the Mustang GT500, cranking out 700 horsepower and 640 lb.-ft. of torque.And it sounds incredible. That was the first thing I was nervous about, living in a community within close proximity to my neighbors. I know how rowdy the Mustang can be, and I 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
A short while back, we looked at the stunning Audi Q3 demo vehicle built by Pinnacle Autosound in Lake City, Florida. We were so impressed with the attention to detail in the project that we decided to do two “behind the scenes” articles on how the project came together. This article examined the processes and techniques used to install the Morel speakers. Now it’s time to Read more
It’s been more than a year since we first got our hands on the amazing Sony Mobile ES XAV-9500ES multimedia receiver for a detailed Test Drive Review. Our takeaway from that testing experience was that Sony had pulled out all the stops when developing this radio: It sounds stunning, measures superbly on the test bench, and, as we would confirm after an extended period of Read more
So, the year is 1993 and a new version of the already great Acura Integra is set to launch as a 1994 model. Your author is graduating from high school, and the Integra soon becomes among the most sought-after vehicles. Sure, there were the wealthier kids with their Nissan 300ZXs and still-fresh Jeep Grand Cherokees. But the Integra could do it all: be sporty, practical, fuel Read more
We see a lot of questions like “My car audio amp can produce 800 watts; how much power does each of my subs get?” If you aren’t versed in the calculation basics of Ohm’s law, the answer might not be intuitive. Let’s dive into the math and logic that will let us calculate how the power from an amplifier is distributed through multiple speakers or subwoofers. How Much Power Does Read more
