I am able to get a 5.1 speaker set from a local outlet rather cheap. Drawback is that is flimsy sounding, although not bad. My amp outputs supposed 100W per channel, so I was wondering whether it's feasible to get 2 of these sets and hooking them up to the amp? If so, would I do it in series or parallel? Does htis sound foolish or has it/can it be done?
