There is a ribbon cable that will still connect the front and back panels once they are pried part.
Use the plastic opening tool to gently pry apart the front and back casing panels. Repeat this at multiple locations around the edge of the device. You should hear the clips that hold the front and back together pop apart.
Once there is a large gap between the from and back casing panels, use your hands to separate the two halves.

This step requires soldering. If you are new to soldering, reference the Soldering Section of Ifixit's Device Skills Page for helpful information on soldering.
Disconnect the speaker wires by desoldering them from the terminals on the motherboard.
Plug in the soldering station and give it at least 5 minutes to heat up.
The soldering iron and molten solder are very hot and can burn you!
Touch the tip of the soldering iron to each terminal until the solder begins to melt.
Once the solder melts, gently pull the wire away from its connection to the terminal with your hands.
