I just moved my sub to the back right corner of my living room so I have to run a sub cable in-wall about 60-70 ft. I read that RG-6 or any coaxial cable would do the trick.


Are there any disadvantages with using RG-6 cable for sub use? Since it's so much cheaper I'm wondering why others don't use it.


Second question is, although I think I know the answer, would it be a bad idea to run the cable (either RG-6 or RCA) down wall next to a 110 volt power line? There's an existing path down the backside of the wall where the power outlet is. I could easily fish the wire through the same path but my senses tell me it's not a good idea. I know the electricity can interfere with the signal and it's probably not safe. Just thought I'd ask in case I'm misinformed.


Thanks in advance for input.

There are many, many types of RG-6 co-ax cable.

Quad-shield RG-6 is designed for broadcast and cable co. frequencies, it is not the best choice for analog audio (but it will work)

The best choice for long sub-woofer cables is a co-ax with a heavy braided shield.

Due to the frequencies that are being carried, I would only use something with a bare copper center conductor and a 95% bare copper braid. 95% Tinned Copper (with foil) commonly referred to as "Precision Video" would also work well.


While it may "work", avoid using any coax with a copper-covered-steel center conductor or with an aluminum braid.


In this application, you need the braid to work as a true conductor and the resistance of non-copper is less than ideal.


Best,


Carl

Thanks guys! It sounds like it will work but isn't ideal so I'll just get a long RCA cable rated for in-wall.
