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 […]

If you are in your late 40s or older, then you likely grew up with a turntable or tape player in your home as a way of listening to store-bought music. Between 1982 and 1983, the compact disc entered the market and forever changed the way music was stored and transported. In this article, we […]

We recently talked about how the conversion from analog to digital works and explained some of the basic terminology associated with digital audio files.

Next, on our look through the common specifications included with modern car audio amplifiers, we want to take a look at amplifier efficiency. With the electrical systems in modern cars shrinking in capacity with every passing year, getting power from your amplifier without taxing the wiring, battery, and alternator in your car is a genuine […]

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 […]
