With that being said, the speakers that you purchase are only as good as the amplifier that is feeding them. If you had to take away one key piece of advice from this article it would be to make sure that your amplifier is configured to output the same wattage as the RMS of the speakers and car subwoofers that it is feeding.

Doing so will drastically reduce the chance of your equipment failing, and will give you the peace of mind knowing that your system is working efficiently and can cruise along for long periods of time without any issues. RMS is an acronym for root mean square, which serves as a precise mathematical way to measure AC signal strength. The term RMS was coined by electrical engineers and has since been adopted in many other disciplines as well including physics, acoustics, climate change research, and many more.

Root mean square is a measurement of how strong an electric current is, with higher RMS power generally meaning more powerful sound. For example, if you were to select two speakers that are being sold and wanted to know which one would give you the most power when it comes to your listening pleasure, then you could use the RMS rating as a key measurement in figuring out which speaker would be better suited for you.

Keep in mind that the RMS power is an electric current calculation, so you will need to know the resistance and length of wiring. You should also subtract any resistors or loads from this equation.

To do so, use a formula:. One thing to remember when calculating your average power is that the power goes up exponentially as the number of speakers increases. The RMS wattage is calculated by multiplying the voltage times the current for each speaker. The idea behind an RMS measurement is that most speakers have a variety of power ratings: rated at say 4 ohms, 8 ohms, each of which might be true depending on the frequencies they produce..

For the waveform shown above, the peak amplitude and peak value are the same, since the average value of the function is zero volts. Peak-to-Peak Voltage V PP The full voltage between positive and negative peaks of the waveform; that is, the sum of the magnitude of the positive and negative peaks. RMS Voltage V rms The root-mean-square or effective value of a waveform, equivalent to a DC voltage that would provide the same amount of heat generation in a resistor as the AC voltage would if applied to that same resistor.

Average Voltage V avg The level of a waveform defined by the condition that the area enclosed by the curve above this level is exactly equal to the area enclosed by the curve below this level. Notes RMS is not an "Average" voltage, and its mathematical relationship to peak voltage varies depending on the type of waveform.
