Give us more details about your situation? Hard to come up with a functional answer without full context. Do you Own or Rent? Is there a Basement or Cellar under the Floor? Carpets or Hardwood Floors, or other? What is the Material Construction of the Room? Specifically, what equipment do you have - Amp, Speakers, etc...? Understand that when you use a Transmitter/Receiver, you lose your Amps. And likely the Transmitter will have to be driven by a Pre-Amp Out. Does your Amp have a Pre-Amp Out? This Tx/Rx uses Speaker Level Input, but highly doubt the 80 Watt claim. You existing Amp probably has very good specs, these alleged 80w amps probably do not. https://www.amazon.com/Wireless-Amplifiers-Model-Better-than-Bluetooth/dp/B01ARM0VE0/ If you own the home, depending on the construction of the walls, you could use Speaker Connection Plates like this - https://www.amazon.com/Fosmon-Home-Theater-Wall-Plate/dp/B00KDOT8DS/?th=1 That way you wouldn't have crude holes, you would have clean Connection Plates. The more details we have, the better we can help you.

well sure but it's not cheap. better off just running wire.
