Hello I was hoping someone could assist with a speaker wiring question. I recently had a TV hung downstairs and the installers installed the receiver along with the center speaker, sub-woofer, and two front speakers. They suggested I get different rear speakers as the ones I had were bookshelf speakers and they said it would not look good. They suggested in ceiling speakers. The cost for them to install was going to be over $400 as they said they would have to cut multiple holes in the ceiling and drill through the multiple beams. I was thinking about trying something different and wanted to see if it would work.
The DIRECTV cable for that TV runs through the wall outside along my house and up into my bedroom as that was the only way the installer could do it. So I was thinking of running the speaker wire from the receiver outside and follow the DIRECTV cable. This would bring the wire into my bedroom where I could run it along the baseboard and drop the wire through the bedroom floor into the downstairs ceiling. My question is would it be an issue to run a wire from inside a house then outside then back inside again and if not any specific type of wire to use?
