    • First plug in the Soldering iron and wait for it to heat up. If your soldering iron has a dial, adjust the setting somewhere between 15 and 40 Watts..

    • Then connect the prepped speaker wire to the same spot where the previous wire was removed from.

    • Next take the new speakers and solder the ends of each set of wires to the logic board. The red wires go to the positive and the black wire goes to negative,which is labeled on the logic board. Do this by touching the soldering iron to the twisted copper wire for about a second to heat the wire.

    • Next, touch the solder to the soldering iron, so that a small amount of solder melts and forms a small bead between the surfaces being connected. (Avoid pooling of solder material by keeping this step between 3-4 seconds)

    • Lastly secure the new wires with the black tape and place the speaker back into its original slot.
