Showcasing the Best in the Mobile Enhancement Industry
Not long ago, we looked at how an increase in subwoofer voice coil temperature reduced the power delivered from your amplifier. With component temperatures easily exceeding the boiling point of water, the impedance of the voice coil can increase by more than 50%. Manufacturers that understand this go to great lengths to include technologies to help keep things cool so you can Read more
A comment came up the other day that it was unwise to use all channels of a four-channel amplifier to power a pair of subwoofers. Not only is this incorrect, but this practice opens up several unique system designs and installation possibilities, especially where high-power requirements are necessary. Let’s dive in! Four-Channel Amplifiers Are Amazing! In terms of application Read more
Shallow-mount car audio subwoofers were introduced more than a decade ago to allow installers to add great bass where space was limited. The first thin subwoofers were optimized for mounting depth, but many still required a large enclosure for good low-frequency output. The latest generation of low-profile subwoofers deliver bass that rivals some full-depth subwoofer options. Read more
Every so often, someone asks if it’s a good idea to upgrade their factory-installed stereo system by swapping out the original subwoofer with a new one. We aren’t talking about building a new enclosure and adding a dedicated amplifier. They want to put a different 6-, 8- or 10-inch in the factory location and connect it to the OE amplifier. The answer to whether or not this is Read more
In the car audio world, terms like subwoofer box rise and power compression are relatively familiar to those who push their sound systems to the limit. So, after extensive research (three minutes) and a detailed planning session (another two minutes), we decided that it would be worth doing an experiment to explain and quantify these elements. Let’s Talk About Speaker and Read more
Thanks to the DSR1 digital signal processor from Rockford Fosgate, upgrading car audio systems has never been easier. Aside from a full suite of easily configurable audio processing features, the DSR1 includes an iDatalink Maestro amplifier replacement interface. Maestro technology can be used to upgrade the audio system in more than 1,500 vehicle applications with reliable and Read more
We were cruising the internet a few weeks ago and noticed a comment from a self-proclaimed car audio expert that new speakers and subwoofers need to be broken in at low power levels. He made it particularly clear that the voice coil needed to be broken in gently. If you’ve ever considered how a speaker works from more than an “it makes sound” perspective or you have a grasp of Read more
Decades ago, car audio professionals were adamant about the statement that tweeters needed to be installed right beside the midrange speakers in your car audio system. Is this accurate? The answer is that it depends on a few variables. Keeping them close can’t hurt, but it might come at the expense of improving the soundstage location in your audio system. Why Did Tweeters Read more
Car audio amplifier designs have changed a great deal over the last few decades. Modern amplifiers have more features along with improved efficiency, and they offer consumers better value than their predecessors. This article will examine the key components in the construction of mobile audio amplifiers, their evolution and their benefits. Amplifier Design Balances Power and Read more
