passive filter attenuation
nope.
the pair of 1k0 and the Rs~200r will attenuate the bass signal by ~0.4db in the LF band.
The pair of 68nF and Rs~200r will attenuate the midband by ~ 1.7dB.
Losses through the passive filters are not the problem, particularly if the chipamp gains are set to +32dB.
He needs to measure the signal levels available at various stages in the signal route.

Wouldn't a 4ohm or 8 ohm load at the output, duly heatsinked or water cooled, and a signal generator solve this question easily?
A scope would show if there's clipping or not and see how many watts you are getting. Can you do that?
