The Dual Banana Plug to use. The new G&H Banana, is the only dual banana plug to use. It's a whole new approach with 30 A current capability. The lantern spring contacts wont break and provide lower contact resistance. The wire termination uses a nut and washer to clamp the wire (that's right no little screws). It accepts crimp on terminals so that even 8 gauge wire may be terminated. Two slots provide for easy strain reliefing, The profile allows 1/2" diameter wire to be terminated and still fit two side by side in the back of your amp.
