2003 ser aftermarket cd player ?
 

i just purshased a 2003 spec v with the rockford fosgate system in it. i would like to install my eclipse cd player that i removed from my old car. the main reason i want to do so is because it has a connection for my ipod. i went and talked to an installation place and they told me if i buy an power invertor i could use the eclipse cd player but he said there would be no gaurentee the subwoofer would work once i did so. anyone have any luck switching cd players and getting all of the factory system to work?
thank you
