A couple of clarifications. only the memory wire for the stereo will run to the battery. The power for the stereo is wired to the accessory circuit.
The TV can run on 12v or 110v depending on which cord/adapter you use. I'm planning on wiring it into the 12v system. My old TV (110v only) lost its channel memory when unplugged. I'm assuming this one will as well.
