I've asked this before, but some of my numbers were wrong so I'm going to ask again.
I have a pretty long speaker run - about 170 feet (I previously posted it was 250 feet). What wire gauge should I be shooting for? The Crutchfield guide that was linked in another post said for a 170 foot run I should use 14 gauge, but last time I asked I was told to go for 12, 10 or even 8.
Once I zero in on a wire size, I'll need to pull it though the conduit. Are there any tricks I need to know? The electriction put a string in the conduit to attach the wire to.
Should I just tie the speaker wire to the string and yank it through?
Should I pull both speaker wires through at the same time?
If I go with large wire, say 10 or 8 AWG, they only sell them in single strands (not pairs). Should I try to pull all 4 through at once? That seems like a bad idea to me.
Also, how should I attach the pull string to the speaker wire? Just tie a knot? I'm a little worried about the thickness of the knot.
Any other tips for a first time conduit/wire puller would be greatly appreciated.
