Coil Speaker

Make a speaker? Help in making the voice coil?

I do my own subwoofer. I have detailed plans with the resources and know I do. Please do not tell me it is a waste of time or too complicated. In any case I have to do a little help coil. I have 3 N42 Neo Magnet 1-1/2 "x 1 / 2" voice coil surrounding it. Firstly, I need to wrap around the roll cardboard or work Alluminum (like a roll of TP?). So do not see how the voice coil has 2 terminals. To start the coil has to stick down 1 end, and after finishing layers, which are covered OK? So where is the 2nd coming? Any help is appriciated. Thank you

"To start the reel you touch of 1 end is totally wrong. The detailed plan is not very detailed. If you strike at one end, then there no way to complete the circuit of the coil. I hope you realize how many laps it takes to make 4 Ohm and clearly how the rules should be efficiency. The last game of the reel (cable) is a terminal. Wrap the wire around cardbaord a tube and using the other end of the terminal. Thus the coil is wound in a submarine. It's the same principle as the relay coil or Solon.
