Stephan,

You said:

"The biggest amplitude is in the bass - so if there occurs clipping it will happen there first and produce harmonics. So I filter the main-amp at the input, that it has to produce no bass."

I'm not sure how your system is set up but for most of us we have speaker level outputs into solid state bass amps. There is a passive filter between the main amp and bass amps. So the bass that the main amp is producing is into a very easy, high impedance load. The bass character is heavily influenced by the main amp, but the main amp will never strain to produce bass frequencies.

It works very well unless there is too much low frequency noise in the system, since any noise will be amplified by the main amp and bass amps.
