I think I may have found a good reason so many folks are happy with it vs those of us that aren't. I've been kinda scratching my head trying to figure out why so many folks get their panties in a wad when we mention the bass sucks or that we dislike the sound after the update.
I normally keep my bass between -6 and -9. That said, I hit the interstate for the first time in a while and once I was going 70+ mph, the wind noise pretty much drowns out the bass.
I work from home and spend almost all of my time driving on back roads and 55mph or lower roads and highways. At slower speeds, where wind noise is no issue, all you can hear is the boom boom boom of the bass. Once you get up above that, the wind and road drowns it out.
My best guess, now, is that everyone who loves the new louder boomier sound spend most of their driving time at higher speeds with more cabin noise. The rest of us, and I'm totally speculating here, spend more time and lower speeds where the sound system is clearer.
If I spent all my time running at 70-80 mph, I think I'd be perfectly fine with the bass as is....as I could hardly hear it over the rest of the road and wind noise.
Feel free to correct me if I'm wrong here. Just throwing it out there as a possible reason for so much disagreement on the bass.
