yo guys....do any of you know how to install speakers into the rear deck of an EF sedan....there are no speakers there now....but there are holes underneath for speakers....im trying to get the deck out but i cant figure it out. the speakers going in will be 6x9 Polk Audio db690's...i know the wont fit flush in the hols but i plan on making spacers....if anyone has any help...that would be great.
