Yep! Here's a link to the latest posts on the thread where I detailed which parts I had put in and some of the tuning I did:

I had my car in for service recently and was given a 2016 3.0T Premium, and that Bose sound system is nothing to aspire to in my opinion. Everything was cohesive, but it was all just a bit...mushy. Like some processing was taking the edge off, making everything soft, even with all (there are a lot) of the "extra" processing options turned off.
Compared to the Bose system, the components I have in mine offer extremely crisp, clean, dynamic sound. I wouldn't put it on the same level as top-tier options from Acura & Lexus, but the *only* thing that occasionally takes away from the smoothness of my system is that there are what sound like some resonances with the sub in the trunk, so occasionally you'll get a strange bass note that's just overpowering, but that's rare enough that I haven't bothered to look into it. I imagine the fix would include some sound deadening. As an aside, I did end up having to put some sound deadening materials on the front doors, they rattled like crazy after the speaker install.
All this to say that if you don't miss any of the other premium features and do want good sound, I think picking up a base Q50 is the way to go. Not that it was cheap, I think I paid a total of about $2k for parts and installation when it was all said and done, but absolutely worth it, and if I'd gotten a Premium with the Bose sound system then I'd have paid *more* than that and probably still be unsatisfied with the sound system. Obviously if you can do the work then you're in better shape financially, and I did splurge a bit on the front component speakers but after living with them for a few months I wouldn't have it any other way. This is my first experience with the Hertz brand but I'm incredibly impressed.
