also how easy would the instalation be? if im taking them out of a gp and puttin em in another gp it should just be un plug from the one and plug em in the other right??
No, the harnesses are different. Even if they were the same, I believe the monsoon speakers run at 2 ohm and not a lot of head units can handle that.
