It wouldn’t be an exaggeration to say that we’ve seen dozens of posts asking about dash cameras that are easy to install and don’t cost much. We’ve all but beaten the topic of dash camera quality to death and have reviewed and analyzed several solutions from Momento and Thinkware. Based on the results of our […]
Many professionals in the car audio industry started their careers as novices installing equipment for themselves or friends in their driveways and garages. That hands-on experience typically led to a job at a local shop and allowed them to learn more about electrical theory, acoustics, physics, and fabrication. Those who have invested time in understanding […]
While participating in some brand-specific online discussion groups, we often encounter the question: “Is it better to use two good subs or one great one?” Are two 12-inch KICKER L7S subs better than a SoloX? Should you opt for two Hertz Cento CS 250 S4s instead of a Mille ML 2500.3 Legend? What about choosing […]
Every fall, car stereo and automotive accessory shops install thousands of lighting upgrades. These days, the most common upgrade is a set of LED headlight bulbs that fit into the stock light locations. While seemingly simple, the resulting beam pattern can be negatively affected if the chosen bulbs are not designed specifically for the lens […]

Our experience has shown that while a GPS-based tracking system might not prevent vehicle theft, it is your only hope of recovering your vehicle. Let’s look at geofence and location-based alerts […]
A short while ago, while testing an amplifier’s maximum power output, we observed how significantly the power increased with higher supply voltage. This observation made us realize that we’ve never thoroughly examined the relationship between a vehicle’s battery voltage and a car audio amplifier’s maximum power output. It’s time to address that. Why Does Battery […]
When 99% of car audio enthusiasts think about a digital signal processor (DSP), they associate it with equalizers, crossovers, and signal delays. In more advanced solutions, a consumer-grade car audio DSP might add the ability to include all-pass filters, an upmixer for a center channel and signal summing. However, at an engineering level, much more […]
Crossovers are an essential part of designing any audio system. From the passive designs used with a bookshelf or floor-standing speaker to three- and four-way electronic designs employed in car audio systems, ensuring signals combine correctly is crucial for delivering great sound. Crossovers can have different frequencies, slopes, and alignments. Understanding how audio signals from […]
