For the subwoofer output on your Sony receiver it is a single mono RCA connection, we would recommend one of subwoofer cables such as the Black Lab for this application. Most subwoofers will have either a dedicated single RCA input for this "LFE" connection or will designate either the L or R connection for the single "mono" subwoofer connection from a receiver.
