You have dc voltage on your output, not good. Do you have another source to hook up the sub to? (even low power) If you can hear it with low power source, try a regular speaker on the sub output (At No Volume Level) I would be willing to bet the sub output is faulty, or wired incorrectly. Hope this helps.
