I bought a pair of rp-3's a couple of months ago, and am running the sub on them from the subwoofer out-on my Denon AVR-3300 to the LFE in on each speaker. I just split the output on the back of my reciever with a y, so both subs are playing the same sounds. If that matters to you and you want them to play their respective channel lows, then you'll need to use the line outs on the reciever. The only thing that I don't like about running the rp-3's how I am is that the only way to limit the output of the subs is to turn the sub out on my receiver down, which also cuts back on any other sub hooked up to the system. If anybody has an idea for getting around this, I'd be interested, as they will clip out when listening to music really loud. As far as running a jumper between the binding posts, it shouldn't be necessary. The multiple posts (high, low) are for hooking them up to a separate amp (one for high, one for low).
