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 […]
A Close Look at Car Audio Line Output Converters
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 Great Digital Signal Processor Configuration and Tuning Analogy
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 […]
Why Coincident Coaxial Speakers Can Deliver Amazing Performance
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 […]

Buying an Entry-Level Car Audio Subwoofer System? Read This First!
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 […]
Car Audio Speaker Installation Location Matters
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 […]
Product Spotlight: iDatalink Maestro AR Multi-Amp Upgrades
Several years ago, iDatalink, the company known for its class-leading remote car starter interfaces, launched an amplifier integration solution called the Maestro AR. The AR (which is short for amplifier replacement) was designed to interpret the CAN bus commands intended for a factory amplifier into something a third-party digital signal processor can understand. While DSP-equipped […]
Understanding Light Color and Illumination
We took our first look at measuring light sources a while back as our first step toward understanding the differences in automotive headlight options. In this article, we’ll provide a practical demonstration of why it’s crucial for the lighting on your car, truck, motorcycle, ATV or side-by-side to emit light that covers the entire color […]
Single Amplifier Distortion Specs Make No Sense
Have you ever looked at something and thought you were only getting part of the story? Many previous articles have discussed amplifier distortion at length but haven’t delved into how power output levels and frequency affect distortion measurements. If you’re looking for the best amplifier for your car audio system, especially for midrange drivers and […]
