We will discuss that in the next section. The goal of a product manufacturer is to sell as many products as possible. Because of this, the manufacturers are more likely to push the peak power output as the main metric in their product descriptions and marketing efforts, because this is what the majority of consumers are excited by.
Peak power output is an important figure to know when purchasing a set of speakers because it allows you to align the numbers with the power output of your amplifier. Now that you understand the meaning and the importance of RMS, you should use this information when you decide to upgrade or install a new car audio system. Configuring your system around the peak power outputs of the individual pieces speakers, subwoofers, head units etc.
All products that are CEA tested are tested using the same equipment and are put under the same testing methods, so the RMS rating is generally very accurate. 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. Many manufacturers also use a maximum max power rating.
A max power rating generally indicates the maximum amount of power that can be safely sustained without resulting in failure. Typically, this is a more realistic maximum specification than the arbitrary use of peak power. RMS power on the other hand, is how much power that amplifier will continuously put out — or how much continuous power your speaker can handle.
RMS values are typically much lower than peak power ratings, but they more accurately represent what an amplifier or speaker is truly capable of. Think of RMS as a true listening rating. Although not a perfect means of comparison, most RMS ratings are comparable — especially when measuring among name brand products. So what should we take away from this? When shopping around for a speaker or amplifier, it is important to look for the RMS power rating.
Remember, peak power is simply the absolute highest amount of power the amplifier or speaker can handle before failing. Max power is the highest amount of power that can be safely sustained. RMS is continuous power handling at sustained listening level.
