CEA Compliant Legitimate Power Ratings

Peak Power = Amount of power the sub can handle for a burst during the loudest point during a song. This number is not as important as the RMS power. This subwoofer has 1.200 watts peak which is a lot of power for a 10 subwoofer.

Program Power = The RMS power the way most middle of the road brands on the market rate their products. This sub can handle 600 watts program power. So for example a 600 watt RMS Hifonics amplifier will work perfectly with one of these.

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 items. This subwoofer is 300 watts RMS CEA rated.
