I'm wondering, is it possible to play audio loud enough to blow the speakers on a PowerBook (12" and 17" if it matters)? I could imagine that the soundcard being matched with the speakers, and the fact it's digital, would mean they'd make it impossible to blow them. But I could see it not being like that too, anyone know? I'm just wondering because when watching movies and I don't have big speakers, using VLC's fairly extreme audio booster is handy, but I don't know if I should be worried about my speakers. Anyone know anything about it? Thanks.
