I have a 300 ft straight hallway that I want to space 6 speakers in. They will be running from an amplifier with fm radio music. I would like to run 1 line of speaker wire down the hallway and have it go from speaker to speaker to avoid having to run multiple speaker lines. My question is can I do this and if so what size amp should I have and what size speakers could I use? What size speaker wire should I use as well? Thank you.
