It's just an audio cable. You need a way to either connect RG-6 (overkill IMO) to RCA jacks, or connect short RCA cables to the RG-6. Flexibility issues and adapters being easier than installing RCAs on RG-6 would steer me towards the latter.
Put an F-connector on each end of the coax, and use a pair of F-to-RCA adapters to connect RCA cables between the coax and each jack. You can get RCA cables with males on one end and females on the other if adapter availability dictates.
This may not be the most cost effective route if you are only building one cable, but if you plan to run more, it's a relatively inexpensive way to make good connections on RG-6... BTW, Parts Express also sells compression type F connectors and BNC connectors and the crimp tool can crimp those as well as the RCA connectors...
