Can they be used to connect 12ga speaker cables together?

These connectors will work as a splice if you solder the speaker wires to male adaptors approx. 3/16 " in diameter then insert them in either end of the connector. Patrick D

Can I order 4mm female banana plugs in less quantity and what's the difference it would cost?

I don't think the price is a big issue. It's good to have a couple of extra plugs anyway

are these 4mm female banna plugs available in a 2 pack?

Dear customer thanks for coming,for your question Yes we can make them in 2 pack, just leave a message when you order.
