Hello tomdad4,
I showed this thread to a few guys today at lunch and the number one question that everyone asked was
1. Why are you plugging speakers into a mic jack?
If you are aware of the laws of physics and you understand that all speakers have the potential to act as mic, then
2. What are you trying to achieve by plugging speakers into a mic jack?
Also, you said that you are having some kind of mic problems.
3. What kind of mic problems are you having and is it related to your question regarding speakers?
