Is there such a thing as too much power? Everyone knows the problems with underpowering a cab, but can you overpower one too? For example, say 1000 wats into a 350 watt cabinet... (Think a Crest CA9 bridged into an Epifani UL112) How do you keep from blowing the speaker? How much power is needed to have good transients that jump out when you need them to? How much IS too much?
