TDA7498E Class D Amp (Zk-ht21)

Hey, could someone help with couple questions about this amp.

What’s the Rms of the Subwoofer Channel?
(I don’t really need the speaker channels)

Would it Run my 200watt rms sub?

The idea: I have the (Zk-Tb21) (TPA3116D2) amp am using to power pioneer 30rms 210max speakers so am looking to buy the (Zk-ht21) board and use iPhone Bluetooth to dual connect them and use the (zk-ht21) for the sub ,as if the amp 160watt speaker channels are rms then 2speakers running in series at 8ohm would still be to much at about 60watt so I can’t use the (zk-ht21) for sub and speakers
