In wall wiring for surround sound, home theater
I'm in the process of installing the terminal block, etc, to hide all the wiring in the walls. My question is this. I bought 16 gauge 4 conductor wire (HiFi Works) from Fry's. So it's 4 coated 16 gauge wires, in a plastic sleeve (red, white, black, green). Seems to me that 16 gauge wire really wouldn't be thick enough, but I don't know shit about this. Should I double up on the wiring, and run say two to each positive terminal, and two to each negative terminal? Or should I run all four to each positive, then another four to each negative? If I were to do it 4 to each, it may pose a problem as all wire ends will be banana clips, and getting all four wires to fit in one banana clip may be a big task.
I know with car audio the thicker the gauge the better, wouldn't it be the same with home audio?
My current setup is an Onkyo 606, Polk RT10s, CS3, PSW505. I haven't bought the rear speakers yet. Keep in mind, I will be going bigger soon. I've been nothing but frustrated with my Onkyo receiver, and will likely be going pre/pro in the near future. I don't want to restrict this in any way, or have to redo anything once the sheetrock is back up. TIA for suggestions.
