I was informed that the only system that comes with a center channel speaker is the Infinity system. How hard would it be and would it be worth it to put in a center channel speaker. Looks like you would have to remove the dashboard. Also, I just installed a pair of 6.5 two ways in the front doors and 6x9 two ways in the rear deck. Could anyone recommend a speaker, tweeter midrange, etc, to put in the wing area of the door by the outside mirrors. Hope to get some pictures posted soon.
