iPhone charger connection to sound?

How do you connect an amplifier to amplify the sound through the charge connector and still be able to charge the phone for an iPhone4 instead of using the headphone out to amplify the sound?

You would have to get the pinout specifications of the apple jack. There is audio going through there as it is used for various docks.
