i have an 08 and i just finished installing some 6 1/2 tonight. they were a perfect fit. i did a search on door removal and front speakers to find out how to take the doors off. if you're not sure what size came in your vehicle the safest bet is to go to crutchfield and input your year and model and it will tell you what fits without modification. if same as the 2008 you have 6 3/4 up front but aftermarket 6 1/2 fit and should have 6 x 9 in the rear. that's what i had with a basic factory set up no bose or monsoon.
