Just bought a 2015 200 Sport a little over a week ago. It has the 10 speaker Alpine sound system. I've already changed out the dash and rear door speakers with Infinity 3.5's. Made a big difference. I have 2 pair of 6.5" Infinity component speakers that I want to install in the front doors and rear deck. Does anyone have step by step instructions on changing out the rear speakers? Also, does anyone have a wiring diagram for the factory Alpine system? Other things I have left to install are 2 12" Alpine subs, 2 sound ordinance amps and an LC7i. Any help or recommendations would be greatly appreciated!
