It's hard to imagine a wall without studs, unless it is made of brick or concrete.
I generally have more success finding studs by rapping my knuckles on the wall with my ear close by.
If it were my room, I would probably try to site my amp(s) near the speakers then run long, balanced interconnect from my pre to amps, so that I could put the rest of the equipment outside my field of view.
