BB, you said,"I ran rg-6 quad / 12G speaker wire....", so that's what I meant. I used the term 'leads' ('pronounced 'leeds', not 'leds') to refer to the wires. I assumed you are looking to terminate the 12 ga. speaker wires to a receiver or amp on one end, and the speakers at the other. I suggested that, while crimping speaker terminals, such as pins or split lugs, can be done well, soldering is generally better, as long as it's done well. Banana plugs are very popular options, too.
