We’re back in the lab and working on a few more articles about amplifier specifications in order to wrap up this series. This time, we’re going to talk about the amplifier stereo separation specification. In a nutshell, the stereo separation, or crosstalk, number tells us how much of an audio signal leaks from one channel […]

We recently talked about how the conversion from analog to digital works and explained some of the basic terminology associated with digital audio files. In this article, we are going to look at how different digital audio compression algorithms work to reduce file size so that files can be shared more easily. The Basics of […]

The problem with using the cigarette lighter outlet in your vehicle is that you end up with a lot of wire clutter and components attached to […]

As the next topic in our series explaining amplifier specifications, we will look at the frequency response information that manufacturers provide and explain how to interpret this information. In the simplest of statements, the frequency response spec will tell you about the low- and high-frequency limits of the amplifier based on its design. As with […]

The next topic in our look at car audio amplifier specifications is input sensitivity. This specification is easy to understand but is important to choose an amp that will work with the system your local car stereo shop has designed. In the simplest of terms, the sensitivity specification determines how much voltage is required on […]
