Kaigoss, Thanks I appreciate it you guys have been a great help.

I will leave everything in the MS8 where its at and just re-calibrate with no sub present.
Once thats done ill re-connect the sub and enjoy it at lower volumes for a little.

Ill also try swapping the +/- ( polarity ) at the amp to see what gives better results.

I was under the impression calibrating with it missing the sub-frequencies it would affect the tune w/your method.

Will try and update thread asap.
