Power Handling in Watts RMS
Sample Subwoofer
Power Handling Gauge
Never exceed the RMS power
handling of the subwoofer system.
Definition: RMS is an acronym for Root Mean Square. The RMS value of an alternating current produces the same heating effect in a circuit as the same value of a direct current.

Explanation: This value represents how much power (Watts) the subwoofer handles. All subwoofers have a power rating which it can "handle" under a continuous load. Typically labeled "Watts RMS".

What To Look For: Look for the amplifier power to fall within the min/max range of the subwoofer's power handling specification. The optimum Power for subwoofers is 30% of RMS (minimum) up to the RMS power rating (maximum). For example, a subwoofer capable of handling 700 Watts RMS would require an amplifier that produces at least 210 Watts (0.30 x 700 = 210) and no more than 700 Watts.
