Now, gently reinsert the terminals back into the opening in the amp wall. Be careful not to stretch any of the three wires.

With a pin or the tip of some scissors, cut a tiny portion of the caulking away from where the bolt holes are to allow for the bolts to go through the holes.

Insert a size 6-32 bolt through each speaker terminal hole. Fasten a 6-32 nut on each bolt on the other side of the terminals. Tighten them very snugly, but DO NOT torque them tightly. You could break the terminals. After all, they're made of hard plastic.

Once installed, apply a bead of caulking around the outside perimeter of the speaker terminals, to ensure there are no air leaks.
