Usually subs can handle more power than rated but it depends on a lot of things. Not to throw this at you but it kills me when people think throwing more than rms at a sub (especially two times more) is whats best for the sub, usually this is only true when competing. Will depend on box size, goals, listening habits, daily or competing/burps (this is the information they should explain as well when telling you a driver can take more power). Next time I would email the company and explain my goals, equipment to get the best answer at what to power there drivers with relative to my application/install. Just a heads up it can be done but under certain conditions, that is why I just stick with rms since it's harder to mess it up even if you know what your doing.
