If you want to push it as hard as you can all the time it's gonna kill them. With my work as a sound engineer working with rigs of 50k watts and such total power and dealing with professionals in the industry I have always been told to match RMS on speakers and AMPs. Gives the cleanest best sound while also not risking your speakers. Of course to each his own. I'm one to have my speakers not be pushed too hard than to have them being pushed to their limits constantly.
