Rear speakers for Non-JBL 05' 4runner

[Editorchops]

I've been doing some research for speaker replacements for my non-jbl system in my 05' 4runner. I called Crutchfield and they claim these (http://www.crutchfield.com/p_158GT16...6A.html?tp=105) are the only speakers that will fit both the front and rear doors. I'd like to purchase either Polk or Infinity for the front and rears, but Crutchfield claims the tweeters on these speakers will rub against the speaker grill of the door. Can anyone provide any info on what speakers will fit both the front and rear doors without having to modify the speaker grills? I plan on using the Scosche adapters for the fronts to mount 6 1/2 up front instead of the 6 x 9. I'm looking into buying these adapters for the rear doors once I find speakers that have the proper clearance:
