Lose Rs 1-4, keep 5-8, lose R11, and lose C1,2,3, then itll be good.

R11 provides some adjustment for sub. Otherwise no way to have any difference
between L & R channel volume and sub volume.

The caps are suggested on the data sheet example:

Why would you do away with them?

What values for the resistors do you suggest?

Thanks.


For that particular circuit with that chip, the caps are necessary
because those inputs are not at ground potential. If you are feeding
normal hi fi unit inputs the caps aren't needed. Resistor values
around 5 to 10 k would be what you need.
