CEA Compliant Legitimate Power Ratings
Peak Power = Amount of power the sub can handle for a burst during the loudest point of a song. This number is not as important as the RMS power. This subwoofer has 1,400 watts peak.
CEA Rated RMS Power = This is an official tested rating by a specific industry standard. This is the way the top brands in the industry such as Kicker, Rockford, etc rate their products. This subwoofer is 350 watts RMS CEA rated. This rating is measured at a very specific voltage over a specific period of time to determine true power handling. You can feel confident matching this with a high-end amplifier from Kicker, Rockford Fosgate, or any other top brand that uses CEA compliant ratings.
