Replacing stock

[SACHEL]

does anyone know anything about replacing stock bose speakers and head unit in 98 acura 3.0 cl. ive looked it up and i still cant figure it out but some say that i would have to replace the whole system including the speakers if i wanted to add on to the car. i dont plan on competing but i would like to keep the bose stock speakers. i am planning though on getting an amp and sub and replacing the head unit. is there any limitations on adding onto the car?

I've never done any installs on a CL, but I checked Metra and American International and the kits offered are a pretty basic set up. Nothing special that says anything about extra items for the bose to aftermarket swap.
They would know... :)
