Answer to: Dropped my speaker and now the sub is looseI have the same problem. I placed the "100" cube on the motherboard and it worked! I placed it just by the area where 2 red wires, 1 white wire and 2 black wires are. Beside it, there are two cylinders. Beside the two cylinders, there is a white outline shaped like a square. Place the "100" cube right there!
