Since you are using them a surrounds, it looks like it wouldn't matter how they sound in stereo mode. For the best two channel music playback, just use the front two, with subs maybe. Anyway, the p363 are overkill for surrounds, but since they are so cheap, there is no reason not to try it to see if it works for you. At the present prices its almost disposable, so its definitely worth a try, in my opinion. Shipping them is probably more expensive then the speakers themselves.
