With a sub cable go from the output of the sub to a plate amp such as this..........http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-802
Place the plate amp near the listening position of you can adjust the shakers on the fly.
From the back of the plate amp (red is +, black is -) use 16 ga wire (or whatever you have have handy), wire
As in this case + wire to + wire on one shaker, - wire to same shaker.
Then + wire from the first shaker to - wire on the other. Series/parallel
I you use more than 2 shakers (auras) I suggest more watts for a the plate amp.
If you have the sub in the front of the room, and don't want to have a plate amp
near your listening position, then just leave it out of sight, and run the wires from
the back of the amp where convenient, along the base board, or underneath
the base board (if this is possible, or if you have base board at all).
Others have not used a base board, and have 2 maybe 18ga or 16ga
wires (with RCA connectors put on each end, after running the wires
under the carpet) and then made connections.
You will need a special device to run wires under carpet,
but for all I know you are on a hardwood floor.
