Default combining a stereo amp with a bass booster and bass adjustable filter

I'm trying to build a 2X15W TDA7297 based amplifier and also bass booster and also a adjustable bass filter which I have found in separate schematics is there a way to mix all them up to make it work together? Iv'e attache the schematics !! The first schematic is of the amplifier, second one bass filter and the third one the bass booster.

Make a lowpass filter and bypass it with highpass filter... Less components and less trouble.
