It would have been neater to cut the holes for the terminals back in step 6, but that's not how I did it. The terminals each need a hole big enough for the connections to fit through. Hold the terminal in approximate location, and mark the place to cut with a pencil. The terminal block is much bigger than the necessary hole, so a little imprecision is fine.

I was imagining this speaker hanging from the handles, so I kept the terminals as close to them as seemed reasonable. Check out the photograph to see how the positions are different on each hemisphere. There are two terminals on each hemisphere. On one, the terminals are close together near the handle. On the other, they are on either side of the speaker that is centered on the handle.

Since you've already got the weather stripping, stick some to the bottom of the terminals.

Finally, fit the terminal blocks, drill holes for the small bolts, and bolt the blocks in place.
