what i have currently done is this:

1) used the ms-8 secret menu and adjusted gains so all channels are within a few db of each other (using an iphone app)
2) calibrated
3) raised morel (11-12 o'clock) and centre vibe gains (9 o'clock as it is bridged).

This isnt the best way as raising gains after calibration will affect the processing the ms-8 does. im planning on getting the infinitys so hopefully i wont have to turn the gains down as much to match.

I was going to get a voltmeter and use the pass through option on the ms-8 to play a test tone @ 1khz, and then turn up gains until its 17.4v (from JL menu). I would then mark this on the amp so i know not to exceed it.

regarding calibrating with gains set at 2.8v, i didnt do this as i thought the rears (ms-8 power) would be a lot quieter than my fronts if i did. i thought that this would negatively affect the acoustic calibration. let me know what u think, i may be wrong!
