LMAO, Sounds simple really.. If you dont know anything about ICE instalations & you cant do an instalation yourself because you cant get the door trims off to see what is already there & you think its just a case of changing speakers without wiring & connection upgrades,. 'Step away from the vehicle' & Get a professional to look. It will take him/her all of 5 minutes to tell you what you have already & what you might fit & what cost. (they are used to giving quotes & it really should cost nothing for a look see & advice.) I happen to really like the speakers & the sound thats fitted as standard, but then i am not an audiophonic person i dont need oomph in a small space.. have fun with it. george
