Ah, the oh-so-complex world of amplifier sensitivity control configuration. One would think that there would be a scientific process that would ensure that an amplifier could be set perfectly every time. But in reality, many criteria affect where a sensitivity control is adjusted. The topic of gain overlap pertains equally to source units as amplifiers. […]

A while ago, we talked about why dashcam resolution is crucial to capturing details in the event of an accident or near-miss. The topic of dashcam image sensor resolution appears to have become a defining factor in the sales pitch from many brands. But is resolution the ultimate decision-maker when it comes to quality? Let’s […]

Not too long ago, we took a look at how speaker-level line output converters worked. We discussed the difference between passive and active devices and explained what features to look for. If you have a vehicle with a premium factory-installed sound system, those interfaces might not be adequate to provide your amplifier with a signal […]

It seems like everything to do with car audio installations has something to do with managing voltages. For starters, your electrical system needs to produce enough voltage to keep your radio and amplifier going. And amplifiers need to increase the voltage to drive speakers. When adding an amplifier to a factory-installed audio system, your installer […]

A digital signal processor, or at the very least some type of equalizer, is pretty much a requirement when it comes to creating a car audio system that will have realistic tonal balance. There are dozens of methods to configure and tune these processors, and each has benefits and drawbacks. What seems to be an […]

A while back we published an article that looked at the issue of intermodulation distortion from coincident coaxial speakers. As the woofer cone moves forward and rearward from its rest position, it acts as moving waveguide for the tweeter. While the phenomenon is measurable, there are other considerations in a coincident speaker design that offer […]

Whether it’s Black Friday, Christmas, Back to School or just a regular sale, many car stereo shops around the country offer subwoofer system upgrade packages that let you add bass to your stereo at an affordable price. These packages typically include a 200-300 watt amplifier, a single subwoofer, an enclosure and an installation kit. We’ve […]

A while back we published an article that discussed why aiming speakers in a properly designed car audio system was futile. As usual, we received a good deal of feedback about the piece. The comments ranged from the typical “that’s not how it works” to more scientific discussions about how even minor changes in placement […]
