I have this box in my 8
Fits AWESOME you have to put it in laying on it's back, like that it fits snug from top to bottom so you don't have to worry about it sliding. Then I have 2 alpine PDX amps mounted on their side one on either side of the box. I can't seem to find the picture I posted forever ago. but it fits nice and still leaves tons of trunk to use for whatever (the trunk well and the areas to the left and right of the trunk well).
