Hi. I am new to running speaker cable so I was looking for some advice.
1. I have these foam wall panels with prerouted wiring channels in them. The channels are about 3/4" wide and aproximately 1/2" to 5/8" deep. I would like run (2) speaker cable down one of theses channels and out to a pair of speaker towers. Is this safe or should I only run on per wiring channel.
2. The channels are spaced 12 inches on center apart. There with be a AC power cable in the next chase over about 12 inches away. There will be 12 inches of foam between them. Is that too close to the speaker cables?
3. Is it better to drill holes in a blank wall plate and bring the cables to the speakers or terminate the cables at the wallplate and bring seperate cable from the wallplate to the speakers.
Sounds like you're in good shape, here are some thoughts:
1. You can run a whole number of low voltage (speaker) cables in the same channel, so a pair of twin cables, like you want to isn't an issue.
2. 12" separation between mains (110v) and speaker cables is used as a typical minimum number (in many cases going smaller is unavoidable) - so you're good here too.
3. My personal preference is to terminate in a wall plate and then use separate runs from the plate to the speaker - it gives a lot more flexibility, and just looks nicer (and more professional).
Hope that helps a bit.
Thanks for the reply. Is it acceptable to run the cables fastened to the bottom of floor joists in the basement if above a drop ceiling or should they be in a conduit or fastened to running boards just like running ac cables?.
They're all analog electrical signals.
The idea is to keep high current, low impedance away from high impedance signal cables, so mixing high current low impedance speaker wires with low voltage high impedance audio signal wires should be avoided.
