Okay, I searched, and didn't find anything regarding this, soooo... I took my Line 6 studio 110, and using one of those little plug adapters, hooked it up to my pc soundcard's subwoofer output. I don't think this should harm the amp whatsoever, but I wanted to see if anyone saw something I'm missing? Otherwise, this setup waaaaayy beats the sub I used to have with my stereo. Wish I still had that stereo, now, and could do the same thing. But anyway, is there something I overlooked?
