Running cable for Sub

[chickenbone]

I love this site! I have been browsing this site for a month now and have found it the most informative out there. I tried doing a search to see if this question has been asked before, but came up empty.

I have a question about running the coaxial for my sub. I am thinking about running my coaxial down the same the path as my electrical line down from my attic next to the outlet. Because the back of my living room comes to a slant, it's impossible for me to get the drill in an upright position to drill through the wood and create a whole to fish a wire down the wall where I would ideally like to be. My question is, will running the coaxial next to a electrical line create distortion or humming effect to the sub from the electricity line? I am still not sold that I will do this because there is no guarantee that I will be able to pull the coaxial cable through the same hole as the electrical line. It was pretty tight trying to get some fish tape down through it. Plus I would be worried about when I am pulling the cable through that I disconnect the electrical line from the outlet.

I have exhausted every idea of how I can conceal the coaxial by going through the attic and keeping the sub in the back of the room. What I mentioned above, seems to be one of my only options. The other corner of the room has a 12 inch header that I would have to drill through, plus a couple of 2X4's to run down that side of the wall. The back wall of my living room is side of the house with brick on the other side.

just fyi you very likely will not be able to fish it through the same hole... it's usually drilled just slightly larger than the electrical wire and trying to squeeze an rca plug in next to it will likely not work if fish tape is a tight fit

Do you have a crawl space or basement? If you dont have any experience fishing wire down a wall you will have a very hard time if you are doing it on an outside wall because of the insulation. If you must do an outside wall See if you can borrow or rent a right angle drill from someone. They are made for this purpose to get into tight spaces.

Simple answer, don't do it.

Signal wire should never be run parallel to power wire at a distance closer than 12" and they should probably be kept 24" apart.

If you went with your plan A (running signal wire through the same hole as power wire) and you get a bad hum what will you do (plan B)? When you figure that out substitute plan B for plan A.

There is also a possibility that running low voltage wire in the same hole as electrical may be an electrical code violation. I'm not sure if it is but can certainly see it being one and I know that co-mingling high and low voltage wire is generally a no-no.

Ditch that idea and find plan B.

One of the big challenges of pulling wire in an outside wall is not compromising the vapour barrier.

I found an alternate solution to get the cable ran. The beam that was on the opposite wall was actually shorter than I thought and there was room to potentially get my drill through. I didn't see this the first time I was assessing the situation. I crawled up further into that corner and found about a 6 inch gap from the end of the beam and the ceiling slant in the attic. I was able to drill a hole through one 2X4 vs. two potentially three like I would have to on the other side. I fished down without resistance since this is a inner wall inside the house and there is no insulation to fight with. I hooked my Hsu sub and it sounds awesome. Thanks guys for the input, no telling what I would of did and if I didn't ask.
