Yea dude, i had no problem at all with my 6.5s up front. Its not hard.

 

for the back speakers, just use a small flathead and pry the grills off, be gentle because it doesn't take much to remove them. Infinity's come with some sort of adapter plate IIRC, so you might end up using that, i've got in infinity 6.5's in the front as well, fits fine.

 

I have the 6.5 infinity's up front and they fit fine. They also sound awesome, I just gotta figure out to get the door to stop vibrating. I think something might be lose in the door so just make sure everything is tight when you put it all back together.

 

everything in a tib rattles, im gonna havta insulate the hell out of this thing

my friend's 3rd gen tib(03) is the same way

 

i just got finished installing pioneer premiere everything in my car 6.5's up front and 6x9's in the rear, plus i've installed lots of head units and the tibs is super super easy to install.

got any questions im me. smile.gif

it's all pretty straight forward. you'll need your soldering gun and some wire stippers though.

edit: oh btw, my 6.5s fit fine, i just had to use some washers.
