Ok i been reading some posts about the 09 speaker size but i am getting some conflicting answers. What i want to know is what size are the front and rear speakers, What will fit with minimal work and do the speakers have a the full freq going to them and the speaker have a built in crossover or is there a crossover somewhere else in the system before the signal is sent to the tweeter and door speakers. Im really confussed to how this system is wired.
