time to upgrade speakers is here

[deniswhite1]

ok well i just tinted my windows, and now is time to upgrade the speakers,
i'm looking at the infinitys on crutchfield.com for the front http://www.crutchfield.com/p_1086022...022si.html?c=3

i read on this website that 6.5' can be installed with adapters, where can i get this adapter? and also read that the depth has to be less than 2", this are 1 13/16 so this should fit right?
i wanted to go with components but they are too deep.

i have those exact ones in my doors an dthey are great, and fit nice with 1.5" spacer
