THANKS! I joined this forum just so I could come back and thank all of you for the help here and in the other threads related to this issue. They have been hissing and popping, the satellites would not power up or would only power up irregularly, and sometimes even gave out a high-pitched squeal. I thought the DIN receptacle on the woofer was wallowed out and causing the problem. Thanks to all of you, I recognized the issue as the male part of the plug (it's always the guy's fault, anyway...), bought the exact Dynex cable at Best Buy, matched the colors, and even learned how to solder (cough, well, sorta). Works great, and the wife is happy, which is always, always a good thing...
The cable is like $3 at Buy More (Best Buy), and the soldering iron and solder was about $10 at Radio Shack, but the experience of fixing it myself...priceless. I see that you still have the cables for sale on Ebay, and I'm sure they are much, much better than my attempt, so I'll probably order a set anyway. Thanks, again.
