I plan on installing 7.1 home theater speaker wires in the attic, using a 7.1 connector box from Home Depot/Lowes at the Receiver end. From there, connect receiver to in-wall box with original factory speaker wires. From the box, use new cable in attic and to outlets at each speaker location. Install a "speaker outlet box" at each speaker location and reconnect to factory speakers with original speaker wires. I am using Onkyo SKS-HT540 7.1 Speakers to connect to Denon AVR-2312CI. The total run length from the receiver to the surround back would be about 50ft.
Heres the issue. The temperature in the attic is over 110F in summer.
I have read a number of posts about Plenum rated wires, Shielded wires etc., but not sure what to use.
I would probably buy a spool from monoprice and run it for all the speakers.
Here are some of the questions that came to my mind.
- Do the speaker wires need to be fire-rated?
- What gauge of wire need to be used?
- Do the wires need to be "shielded" type?
- Will there be intereference if all the cables are bundled together in the attic?
- Do the cables need to run inside a conduit in the attic?
Any help is appreciated.
