Ok, I have some cheap radio shack powered speakers.
The other day I found a powered subwoofer and hooked it up, but for some reason I think I did something wrong, because now my cheap radioshack speakers are rediculously loud. I have the windows volume one tick over mute and they're still really loud. I have the sub hooked up the the sound card out and the speakers connected to the subwoofer's out. I know its probably something really obvious, but I don't know much about subwoofers or speakers in general. The subwoofer was part of the Boston Micromedia System.
