What does RMS stand for in car audio?

It’s most commonly used to describe the sound pressure level of any sound within a specific frequency range. The units are usually measured in decibels (dB). The lower the number, the quieter the sound. A 15 dB system will sound about one-third as loud as a 30 dB system.

What does RMS mean in car audio?

The acronym rms stands for Root Mean Squared. It’s a way of expressing power in terms of energy. A 10-watt amplifier puts out 10 watts of power. If someone says an amplifier has an RMS output of 15 watts, they mean that 15 watts is the output of that amplifier when it’s working at full power. An amplifier with an RMS power output of 20 watts puts out 20 watts at full power.

What is RMS in car audio?

The acronym “RMS” is an abbreviation for root mean square. Root mean square is a measure of the strength of an electrical current. The higher the number, the greater the current. So the higher the amplitude of your audio system’s signal, the greater the current it produces. Most modern car audio systems use RMS as the standard for determining system power. Very high-end systems may go as high as 20k RMS.

What does RMS mean in car stereo?

If you’re wondering what the RMS stands for in car audio, it refers to the Root Mean Square value. Root mean square is a statistical way of measuring anything that has an average value. RMS is a measure of the energy that an electrical signal produces. In the context of sound, the RMS value is a measure of the amplitude or volume of sound at a given point in time.

What is RMS in car radio?

In the United States, we all measure sound pressure levels in decibels (dB). Decibels are a logarithmic unit that measures the relative volume of a sound. The standard unit of sound pressure is the “pound-force per square inch” (PSI), and a 10 dB sound pressure level is equal to a 10 pound-force exerted on a one square inch area of a surface, such as the surface of your car’s interior.
