Anyone have any thoughts as to the best power source? I have a 2011 Limited. I am going to run the wires down the seat-back. I want the wires completely hidden. I thought i could find something in the center console which would be easier than going all the way up under the dash, but the only clear source to me there was the ac running from the inverter to the 120 plug in the console and the units are dc so that is not a good option. Also, the wires are really thin in the console so I wasn't sure about the load of two units. Anyone successfully do this? Thanks.
