yeah, sort of....except my comments say as much about my OCD as they do about the MS8. Im an old school audio guy and in previous cars I have spent hundreds of hours with an RTA and 32 band EQs and moving speakers, changing angles, etc... remember when you would place speakers in the kick panels and drive around for weeks getting the angles just right?
Well the MS-8 eliminated that, I was 80% good from the beginning. It just seemed like I was having to do to much EQ correction so like you I tried everything looking for the best results.
The original kaigoss work around of disconnecting the sub sounded fine on the first try but left me with doubts about lumpy frequency response on the low end...could it be better?
The second kaigoss trick of using the crossovers worked perfect and leaves me with no doubts that things are maximized.
Sorry it didnt work for you.
