Amazing. PencilGeek and I have almost the exact same settings.
I think most people will be pretty happy just using PG's EQ settings. I'm a pretty serious audiophile with my home system where I've got over $30,000 invested, but getting too carried away in the car just doesn't make sense to me with the Active Autowerke exhaust and V8 roaring most of the time. I just set the system so that vocals and orchestra sound natural, then everything else just works out fine.
My partner has a Mercedes AMG 55CLS. Talk about a stereo that sucks...
