Subs, Speakers and Electronics with an RMS Power Rating of 300-Watts
The RMS rating of any speaker or subwoofer driver is the continuous power rating that the driver is designed to handle at a maximum volume rating. The RMS rating is one of two numbers to go by when pairing your speakers with an amplifier. As an example, a speaker with a 300-Watt, or 300W for short, RMS rating should be paired with a three-hundred-watt RMS amp. We usually recommend a power-plant to be over powered by 10 – 20% RMS so that the amplifier does not have to work at 100% capacity to get 100% efficiency from your speakers.
