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
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
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
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
We were hanging out at a mobile enhancement industry trade show recently. As always, we were talking to manufacturers, distributors and retailers about topics for articles. If we can educate you as a consumer about something, you’ll stand a chance of becoming better clients. The subject of Harley-Davidson motorcycle audio upgrades came up with the guys from Rockford Fosgate. Read more
The late ’60s were the glory days for rear-wheel drive, V8-powered muscle cars. They looked fantastic, and most had massive engines that made them pretty fast. What they all lacked was a nice audio system. There wasn’t much available by way of car audio upgrades. Fast-forward five decades, and things have changed dramatically. Car radios have evolved from simple all-analog Read more
There’s a video floating around the internet of someone attempting a J-turn in a Range Rover into their driveway. It all goes wrong, and the truck rolls over, resulting in the subwoofer enclosure flying out the back window. We’ve discussed how important it is to ensure that all audio system upgrades to your vehicle are secure. Let’s look at a moderately over-engineered Read more
We recently published an article that explains how differential inputs on car audio amplifiers and signal processors work. Just after that was published, we were talking with Brad Ott, executive vice president of operations at ARC Audio. He has an extensive background in circuit design and was the company’s product development manager for many years. Brad offered to send us Read more
