I'm helping a friend install a new stereo/home theater in her condo, and I need some advice. I installed nine in-wall/ceiling speakers which need to be connected to a Denon receiver. The building contractor ran all nine speaker wires to one wall plate near the back of her entertainment center, but the wires will not reach the receiver (they only come out about six inches from the wall). I thought about installing a wall plate with banana connectors, but there don't seem to be any with more than 4 sets of connectors, and I don't really want to cut another couple of holes in the plaster to make room for three of those plates. Should I splice some speaker cables to the existing in-wall wires and hide the splices behind one of those wall plates that have a big hole in the center? I'm leaning that way, but I don't know if it's the best way to do it. Thanks.
