Are you not a fan of the deep bass IN your music, or are you not a fan of adding more deep bass TO your music? Big difference, philosophically and pragmatically.
If this is for the E60, the doors are shallower than the E90. I recommend the Rainbow Sound Line 210.25 if you upgrade the fronts.
If you are adding an MS-8 to the E60, and it's not Logic 7, that should be interesting. Use the speaker outputs from the M-ASK, not the preamp outputs, and then use the speaker outputs from the sub amp as well.
I've never tried putting Morels into an E60, so I don't know if they go. I know they don't go into an E70 X5 without major custom work.
I think that with an MS-8, the SWS8 is probably a fine woofer, given that the MS-8 has 8 opportunities per channel to fix any sonic issues.
