Ugg yes, sorry, I wrote this late. I promise you I am not an idiot lol.
Also I am most definitely looking for something much more then a cassette adapter.
Crutchfield and other outlets sell adapters that will match the output of an aftermarket HU to the existing Bose amplifiers.
They didn't have anything vehicle specific for bose adapters for Infiniti, but they did have Audi's, mazda's and GMs.
