TAS5720L: Asking for the TAS5720 woofer setting

Part Number:TAS5720L

Hi Team,
Cusotmer would like to design 2.1 CH system. maybe TAS5806/TAS5805/TAS5825 for stereo, and TAS5720 for mono. stereo amp's DOUT connect to TAS5720 DIN

1. If using TAS5720 for the woofer, can the low pass EQ set inside TAS5720?
2. If TAS5720 cannot set low pass EQ, can the woofer low pass EQ set inside TASTAS5806/TAS5805/TAS5825?
3. If the TAS5720 din from stereo amp DOUT, how about the rest of clock pin? Just tie MCLK/BCLK/WCLK together?

Thanks,
SHH
