Does the Power Your Car Audio Amplifier Produces Really Matter?
Did you know that a difference of 20 watts of power between one car audio amplifier and another might be completely inaudible? That same 20-watt difference might mean having to keep your windows rolled up on the highway to hear your music. Let’s look at the physics of reproducing sound with moving-coil loudspeakers and why […]
Your Installer Can’t Tune Out Distortion with a DSP
No matter how hard he or she tries, the installer who’s calibrating your car audio system can’t use a digital signal processor to tune distortion out of your system. We aren’t talking about the harmonic distortion that happens when a signal overloads the processor or an amplifier’s input stage. Preventing clipping is a simple process […]

Saying ‘Gains Set Halfway’ Is Concerning to Car Audio Professionals
If you’ve browsed amateur car audio groups on Facebook, you’ve likely seen someone post that they have “set the gains halfway” on their amplifier. Their misguided theory is that this setting will limit the maximum amount of power the amplifier will produce. Saying this in the presence of a professional installer is the best way […]
Why Would Your Car Audio Amplifier or DSP Need a Bandpass Crossover?
When designing and integrating high-performance speakers into your car or truck, your local specialty car audio retailer might suggest choosing an amplifier or signal processor that includes a bandpass crossover. If you aren’t used to designing speaker systems, a task that most consumers don’t concern themselves with, then the term bandpass might be confusing. Please […]
Why Mid-Woofers Won’t Work Well in Small Speaker Enclosures
Dash pods, kick-panel enclosures and sealed enclosures in doors might look cool, but they aren’t always an ideal solution for a speaker that will attempt to produce bass. In this context, when we talk about bass, we are discussing audio frequencies below about 300 Hz. In this range, most drivers with a cone diameter of […]

I vividly remember being in one of the Korbon Trading (the Canadian distributor of Rockford Fosgate in the ’80s) Blastro vans. This GMC Safari had four 18-inch Punch subwoofers powered by a […]
Should Your Car Audio Speakers Be Mounted in Pods?
Speaker pods and build-outs on A-pillars are becoming increasingly common in custom car audio installations. While some of these solutions look cool, the laws of physics can work against these cosmetic efforts to degrade the performance of your car stereo system. The subject of speaker installation could (and should) fill a book. In this article, […]
Your Car Audio Amplifier Wants More Battery Voltage
If you’ve looked carefully at the specifications of car audio amplifiers for any amount of time, then you’ll know that some designs make more power when they are connected to a higher-voltage electrical system. This type of amplifier is called an unregulated design. In the simplest of terms, it multiplies the provided battery voltage by […]
