Hi another quick question. I bought this amp and don't know where to power the board or connect the right and left audio from the GameCube motherboard.
I know how to wire up the speakers and switch headphone jack but where do i solder power and connect the right and left audio.

Here the amp - http://www.aliexpress.com/item/F05715-D ... 26365.html

Vcc is power, INL is left and INR is right.
