Bose System Differences?

2021 CX-9 GT
For comparing the 2 systems, besides the obvious Bass/Treble/Fade, def check Centerpoint. It changes the staging versus standard stereo.

Also, in addition to adding sound deadening material to the outside of the sub, I’ve read that people have also added cotton stuffing to the INSIDE of the bass enclosure. Can’t remember what the reasoning was but it was suppose to help clean up the sound by sharpening he bass and letting the mids sound clearer.
