Great post Scott!
I would never have thought that a change like this would be so 'noticeable'. I would, if you were going from stock to a good sub frame - but from one aftermarket sub to another I wouldn't have thought it was such a big change.
That makes it all worthwhile, 'cause this is not that simple of a swap on a "done" build.
EEEEEEEEEEEEEHHHHHHHHHHAAAAAAAAAAAAA!
