how do you connect an audio amp?

[devileyebrows42]

im going to make an n64p in the future and i was going to use one of those 3.5" screens from ebay but they have no audio amp. I was going to use one of these (http://forums.benheck.com/viewtopic.php?f=8&t=35308" onclick="window.open(this.href);return false;) because its small and already assembled. What do you do to connect it to sound. I was thinking that you find a 7805 regulator on board, connect 5 volt source, then wire in to system ground, and connect the systems audio signal to which pin? If this is way off just tell me. im still learning

You Would Connect The Input L/R/G To The Place Where The Cord Goes On The Board.

Then The Output Ground would be both Black Wires on the Speakers.
In This Picture (underside) The Left Red Wire Would be Right Audio
In This Picture (underside) The Right Red Wire Would be Left Audio

Some Thing Like This.
