I apologize in advance if this is not the right sub to post this in. I have a pair of Polk Audio T15 bookshelf speakers that I had connected to a small Dayton Audio stereo amp in my garage and connected to an echo dot for music. I then swapped that for a Bluetooth speaker and was using the Polks on a TV until I further updated that setup. Well now they just sit collecting dust and after expanding my deck off the back yard and creating a living space with couches and space for a projector screen for movies, I thought maybe I can use the Polk bookshelves in this space instead of my projector built in shitty speaker. I am wondering if there is an option out there where I can transmit the 3.5mm audio out on the projector via Bluetooth to 3.5mm reciever on the small Dayton amp I have. My goal is to essentially use these powered off a battery pack and set the speakers up by my screen on the deck railing and minimize cords/cables running across the deck that people could trip on and damage anything. Thanks in advance, and if there is a better place to post this...please let me know!
