Hey all. Recently just had a big party and I have these two Sony speakers that we used. As the music was playing and I left them under the watch of someone else, I come back to find that sound is only coming put of the smaller speakers and not the bigger, bass speakers. The volume and bass levels I left the speaker at have worked fine multiple times before, so my fear is someone turned them up higher. I have tried unscrewing the speakers and all connections look fine. Any ideas?
