Sub backspacing, New deck

Last weekend I did a little bit of work on my sub box and installed a new deck, an KW-AVX810. My subs were hitting the back of my rear seats, so I decided to set them into the sub box, I pretty much just cut a bigger hole in the box and screwed and siliconed a flange in behind to mount the sub to. I had to wait a couple of days for the metra dash kit, I had bought the scoshe kit before, but it didn't fit at all, not even close (it fit the truck but the deck was too big.
