Muzikat, Smol;, Stanwal - thanks. I had realized that in order to go through the tape I would need to adjust the sub every time I adjusted my volume. This is far from ideal but maybe I am stuck with it unless I can find passive box like you suggested.
TPreaves - apologies for bullying accepted. I also forgive you for the bullying on my other posts. I do appreciate your often helpful suggestions but am sometimes at a loss when you become judgmental and condescending. You helped me with a very naive speaker connection question as a newbie and afterwards on a totally unrelated post regarding musical tastes had to chirp in with "oh, did you ever figure out how to connect your speaker cables" in an effort to make me look stupid - uncalled for. For the most part you seem like a nice helpful guy but ruin it with the attitude and I have seen you getting your ass verbally kicked for doing this to other people on the site - really unnecessary.
