Dear Customer,
Sorry that we are not sure whether BP-WBAIX79R4BEFCBNPACBK-CLBK is compatible with RIVE too. Do you have the PCB photo? Or you can download the installation guide of this mono block and compare two motherboards.
BP-WBAIX79R4BEFCBNPACBK-CLBK has been stopped producing.
We only have the black one in stock.
