Coax cable works fine for a sub cable[/quote]
Yes these will work just fine to convert the standard male F-connector you typically see on coax cable to the RCA connector for your subwoofer. If you don't yet have the F-connector on the cable you can either get the crimp on ones (requires crimping tool) or there are some available that twist on too. Working with coax isn't hard, but can be tricky if you haven't done it before. Get someone to help you if you can. Welcome and we hope you enjoy your speakers.
