Need help

Guys have some big questions? So been reading all the post with the kickers upgrades. So I ordered my speakers about 1 month ago but they recommended me to buy the DSC 6x9, DSC 6.75 and the kicker Subaru tweeter. I also bought the kicker key180.4. Can this set up work or do I need to purchase new door speakers? Any one do this set up I see that everyone bought components. Did I mess up buying the ones I did? Also how did y’all wire the dash speakers to the key if the key is only 4 channels do I just hook up the front and rear speakers or do I do the dash and front speakers and leave the rear out. Need some help.
