Better to use 12GA stranded copper, single conductor for each polarity. Go to Lowes or Home Deport and get 12GA stranded copper THHN from Smithwire. Cheap and pretty darn good.
Are there any issues with connecting speaker wire in this manner?
I'm considering purchasing some 14 awg solid core wire to use as speaker cable. I will be doubling this up to make 11 awg speaker cable. My amplifiers, Red Dragon S-500, have binding posts which DO NOT have a hole drilled in the center of the shaft for inserting wire (they are hollowed out for banana plugs but that's not what I am referring to here nor do I need). I'll be connecting the speaker wire without attachments, no spades, bananas, nor pins. To get a good connection, it would be ideal if I could take the wire and, at the half way point, wrap it around the amplifier binding post, then run the two ends out to the speakers. Will this work or will connecting the wire in this manner be problematic? Do I need to cut the wire into 2 runs? Thanks!
