Alright I decided just to purchase the g35 w/o the Navi, and just go w/ the dash kit and after market screen. If I go w/ the premium package and get the bose system, will that work w/ the after market monitor.

My mom has a 1990 Nissan Maxima w/ a bose system. I remember the speakers were 1ohm each. How is bose system in the g35, will it work with a aftermarket screen?

 

I think the premium bose system is decent, although it doesnt compare to what you could get for the same money in an aftermarket system.

The speakers in the bose are 2 ohms, they wouldn't work with your headunit without some prior conversion.

Regardless of how easy it is to get the system to work with the bose components, if your going to be spending the $1000+ that it will take just to replace the headunit, it wouldn't make sense to spend the additional time and money to get it to work with the relativly cheap bose components. Just skip the premium package and replace everything with aftermarket components, its the only way that youll have a system that has sound quality that would justify the amount of money your going to drop into the head unit.
