This is my first post, but I've been reading the forum for ages. I'm planning on getting a whole new surround setup (receiver, 5 speakers, sub). I like the SVS subs, but I don't have an "old receiver lying around" to power it. Most receivers nowadays come with 6 or 7 channels of power. Since at this point I can't afford more surround speakers, could I use some of those extra unused channels to power the sub? I figure in order to do this I would have to run a patch cable from the preamp sub output to one of the inputs and run speaker wire to the sub from one of the unused channels, but then it's impossible to set the receiver to more than one input at the same time, isn't it? Or maybe there is a receiver that lets you reassign internally a surround channel to a subwoofer channel? I could always get a powered SVS, but that would just be too easy, wouldnt' it?
