Coupling Banana Plugs

Thanks Al, The one highlighted in yellow is what my DIY looks like.
It seems all that would work on the image link that you have provided is either in China or the UK. Nothing in the USA.

OK. Since the couplers have uninsulated metal, make sure of course that the two couplers used for each channel cannot come in contact with each other, or with anything else that is conductive or grounded. You may want to wrap them with electrical tape.

Good point. I used some clear thick spiral wrap around the metal.

For your rear speakers, there's really no reason to use expensive cables. A spool of Audioquest or Monster should be all you need. Use anything more than that, and I don't think you'll be able to hear a difference.
