2006 grand prix gt

i understand it has a monsoon system (which is most hated.)

all i need to know is the correct solution to finding the 12v remote wire on stock head unit without getting a switch or messing with other fuses (if possible).

I dont even know if there is even such a thing. Ive read too many conflicting stories on this.

I just want to install my new amp and subs so if anyone can please help?

last but not least. would it just be easier to get a new head unit rather attempting the stock?

im in the middle of wiring and need to know which route to take.
