I have a 15 SCrew with the radio with the 4" display. I saw a setting for Occupancy mode (optimize driver, and optimize all). I tried Optimize driver and it sounds much better in the front the optimize all.

How does the Occupancy mode work? What makes it sound better up front and what does it do to the back passengers?

 

Probably a time delay so the sound from all speakers reaches your ear location at the same time. Sounds more natural.

 

It probably just raises the volume and bass of the front speakers. It basically is a predetermined EQ setting.

 

I'm pretty sure it just tweaks balance and fade to put you more at the center of the sound.

 

I like Driver mode when I listen to talk radio. I usually change it to All mode when listening to music. Just a preference thing.

I use a line level output converter for my Sub amp so the All setting usually sounds best. The driver mode pulls sound from those rear speakers which dulls out my subs sound.

 

I can definitely tell that the sound is more crisp. It almost sounds like it's coming from the center speaker in the dash. I had my fiancé sit in the back and she said she couldn't hear any difference from the back speak when I switched between optimize driver and optimize all. I think it sounds much better in optimize driver but I don't want to jeopardize the sound in the back seat.

Tomorrow I will set it to optimize driver and see if it changes any of the settings.
