In this part of the video, the speaker amplifier blocks are assembled by covering the edges with glue and ensuring a good seal with clamps. The speaker output wires are soldered to the speakers, the front is glued in place, and a glue that expands is used to fill in air gaps. Draft excluder is added around the perimeter for sealing, the battery pack and switch are soldered and secured, and fabric is attached for aesthetics. Mesh is recommended for covering the passive radiator to prevent damage. Speaker feet are added for stability, resulting in a splendid final aesthetic for the homemade speakers.
