I am not exactly sure where this question should go so I figured I'd put it here. Long story short (I'll try): Building a house. When the framing went up I wired everywhere I could think of that I might possibly want a speaker. In my main living area I am putting together a home theater system. I ran a group of 3 wires under the floor to where it will come out where the furniture will be. (1) RCA Subwoofer wire My thought was that if I wanted a subwoofer in the living area sometime in the future I would already be wired for it. (2) 12AWG Speaker wire I also thought that my side Right/Left channel speakers would also be wired under the floor, come out under a couch/chair/table (some furniture) I hate wires and want to hide them at all cost. Next week the electrician is finishing up and will be putting an outlet with a floor box near where I want these wires to come out. I also need to bring these 3 wires up through the floor so that they can be connected via banana plugs to the passive side Right/Left channel speakers (I wont be doing a sub here for awhile if ever). Researching a "floor box" to do this, all I could find were boxes that have XLR connectors on them, nothing with normal passive speaker connections: Example 1 Example 2 I have no idea if I'm going about this all wrong or what but I don't see an option for an "XLR to Banana" type adapter OR if that's even what I want to do. Any and all suggestions would be wonderful! Thank you!
