ok so i have been on crutchfield.com and noticed that when i put my model xa in to help me choose compnents that fit my car there are hardly any speakers that fit mostly expensive component speakers. it states 5 1/4" front and 6 1/2" rear but shallow mounting depth. so far i have done interior lighting and head unit as well as install a flip down monitor for the dvd HU. i want to do the speakers but would like to know what size to get without having to take everything apart first. any one know the truth here or is crutchfield full of crap?

 

You can get 6 1/2" all the way around. I mounted in my xA, in front, 6 1/2" Infiniti Reference component and shallow mount 6 1/2" Infiniti Reference in the rear with the Inifniti Basslink II.
