"Of course, we'll have to dig up your garden to add a second pair of wires to make that double-voice coil speaker have both channels. Shouldn't be more than a few hundred dollars."
Slap a speaker where it's needed, connect where you can, be done. They really don't care.
Sorry, I'm not a fan of half-assing stuff. not even for family.
Are you somehow adding one more speaker without adding new wire?
