3 weeks is a long wait for your first pair of QS8's. It's only been 4 days.
For wire placement, I'm thinking about going down wall on inside of wall, coming out of wall behind base board, into indention made into drywall down through hole drilled through hardwood floor into basement. All hidden by baseboard.
The hard part will probably be fishing the wire up, or down through wall. Wall has old blown-in insulation, so going through that won't be a problem. It's all crumbly.
I ordered 60 foot of wire, 30 foot per side, which should be enough. If not I have about 2 pieces of 10 foot laying around I can splice into it for added length.
