Not stupid question just stupid answer. Sorry about that, no harm intended. I have heard of after-market jumpers, just not sure what the name is. I'm sure someone on this site will help you out. Good luck.
You should try to find a Brown Electronics Lab set of jumpers. They're the best thing I've ever heard of unless you're bi-wiring. The cable in your speakers is NOT necessarily what you want for jumpers. Try Audio Concepts in Houston. Their number is 713-527-0774. I'm not an employee, but they have been great for me in the past.
