Hello,
We are using the LM4673, with 0.1uF capacitor and 76.8K resistor on each of the IN -/+ from several different speaker types while testing. The speakers are 6 and 8 Ohms. We are looking for a solution to drive the gain down to eliminate static and crackling from the output sound. Here are spec links to those parts:

Using the attached PDF file as a reference, we would like assistance in understanding the equations in "Proper Selection of External Components" on page 12 to determine possible capacitors and / or resistors to use as a solution.lm4673.pdf
Thanks,
