So I had a Vizio 5.1 surround sound sound bar with wireless subwoofer and the rear satellites hooked up to the wireless subwoofer. The sound bar died. I purchased Onkyo 7.2 receiver model TX NR 656. Obviously the subwoofer will not connect to the new receiver and I can't hook it up passively. I need to solder in a single coaxial cable somewhere on this board bypassing the Bluetooth slash wireless input so I can get signal to the amplifier inside the wireless sub I'm sure this is possible for someone who knows what they're doing and that is not me. I have minimal electronic experience and I can solder any help would be great the picture of me pointing used to where the actual sub connect to the board
