did I blow the my system?

I've got a sub woofer and 4 speakers by altec lansing that i got with my computer. I was testing out the sub and it sounded great so I had it cranked for about 15 minutes. I come back and the nothing works. The speakers turn on but don't play. all the volume and settings are up. any suggestion?

they have modes, such as, game, aux and dvd. if they arent on your mode that you have the box set on then it wont play :)
