I believe there are two red and two black wires inside this cable. Combine the two red to the (+) positive terminal. Combine the two black wires to the (-) negitive terminal. If your speakers have binding posts I suggest you attach them directly, bare wire. If they are the "spring-loaded" variety, then you might consider using Radio Shack gold-plated connectors made specifically for this type of terminal.(Twist the wire together. Crimp. Then solder.) "Do I need to wrap the wires???" If you mean should you twist them together, Yes, IMO. If you mean should you use shrink wrap, IMO not really necessary. If your thinking of using the AQ banana plugs (set screw), I would removal aproximately 3/4 inch of insulation from the wires. Twist together the two wires. Bend in half forming a "U" shape. Solder together using "silver bearing" from RS. Insert wire inside plugs and set screw down on the horizontally positioned wire. Your best connection is determined by your type of terminal. IMO, bare wire sounds the best if you have binding posts. Otherwise if the terminals are the "spring-loaded" variety, refer to above. You have a really easy wire to work with being it is solid core. These are my opinions. Proceed @ your own risk. Use caution. Double check everything. Make sure equipment is turned "off" when connecting interconnects and spk. wires. Good Luck.
