On them, or in them? I've heard of no kit as of yet. I had to custom fab mine in there. If you want them to fit under the factory molding (like I do) you are limited to the 8" size, if you want to be able to return the door to stock easily. If you want to tear out a good chunk of inner door skin, maybe a ten, but then you ruin the structural integrity of the door. (Wasn't too crazy with that option...) Check my link and you'll see how tricky it was.
I may add the second one in sometime, but my attention is now on getting cruise control installed.
I live in my own little world, but it's ok.....
they know me here.
