I didnt mean for the info to confuse the OP its just always been a legitimate question of mine. Sorry to OP.Novices will have no clue what clamped power means. Best thing to do is to match amp rms with sub rms, assuming using quality equipment that's not overrated. Many here calculate in parasitic loss and box rise, running many more watts than the subs are rated at. Experience is key and giving out willy nilly info can lead to damaged equipment for beginners.
