OK so pulled this from a set of PC speakers. problem is they were damaged and the board was destroyed as far as i know it it still works fine but i need to rebuild the circuit and want to make a full range speaker amp.  http://www.datasheetcatalog.org/datasheet/rohm/ba5406.pdf Data-sheet.
In the pic attached i highlighted the areas of concern, Taken from the data sheet.

Firstly:
On pin7 i assume the cap is for Decoupling as on Pin6?. They come from the filter pins on the IC
On the input side before the DC caps can i just put a 100k Stereo pot in series or is there more that i need.

Thanks in advance :)
