lol! this has to be the funniest thread. anyways the theory is that speaker jacks output right? 🙂 and mic jacks input! so there is no possible way to blow your speakers, instead your speakers would act like a microphone. (a crappy mic). 😀. to be safe, make sure your speaker volume is at a minimum when you plug it in, cause you might hear a little "zzzzzzzzzzt" noise 😉.
