I suppose you could, but I'm not sure why you would want to. One (1) kit will send a signal to two (2) speakers. Wiring is included in the kit, but it's rather cheap wiring and I would use between 12-16 gauge wiring instead of 18-20 gauge. You will need to run wires from the left and right channel of a stereo receiver to the left and right channel of the sending unit, and wires from the left and right channel of the receiving unit to the left and right speaker.
