Secrets indeed.
All I ever wanted to know is what kind of speaker wire you use.
It's all very nice. A good emergency break might be of some benefit on that driveway.
Well, we are lucky that it doesn't snow here. But, yes, it is not for the faint of harts
Especially pulling the truck in on the left side of the house, out of the picture.
Oh, the wire. A while back I replaced some with low voltage landscape 14ga, wire behind the built in. The in wall to the speakers are twisted 14ga if I remember. The subs are passive and has the same to it. From the wall it may have some old heavy gauge with dark blue insulation that is semi transparent. Don't remember the name, not expensive for sure.
