The Quick connects are surplus... Mark ships special built quick connects with the A12 for those using overthick speaker cable as you are.

Thanks for the heads up, I did not know that. I will update the materials list.

If you haven't bought those things yet, i'd suggest different binding posts too -- and wire.

I would greatly appreciate the recommendations for binding posts as well as cable. Thanks!

We use single strands from solid core CAT 5 cable. Preferably plenum grade with teflon insulation.

We use posts with much less metal in them. They are actually hard to find because i guess they look too cheesy to sell via pictures. We order them 200 at a time to get them. Neither Madisound or PE have them. PE has something with the same posts, they do not fit our requirement that the posts don't stick oit (where they can easily be crunched)

Gold Plated Banana 5-Way Speaker Terminal 260-302

These are the same posts but the cup requires a larget hole (we only need 2" holes. harder to get your finders in, but less of the panel isremoved to mount them.

High Power Terminal with Fuse Holder 260-293

Planet10,
I use solid core wire from home security system wiring which is 4 conductor 22 awg, and I thought that is small so I double two wires ea. I think the 22 awg can handle about 1 amp over typical distances for speakers. Cat5 is 24 awg, even smaller. You like having some resistance in your wires for audio quality?
Btw, the binding posts you show above are the same as what I use except my are nickel plated. I like them.
