Working on a spec house, builder called us in a little late for prewire. Drywall is up but we have basement access. I need a low cost idea for a multi room system with either cat 5 volume controls or no volume control, app based like sonos. It is 4 zones. Sonos is $2000 for 4 connect amps and the the builder don't think he can get that back out of it.
I can run a cat 5 for a keypad/volume but probably not a traditional volume control because I will be running all speaker wire through a basement to attic conduit.
