Thinking about getting the sub box from Brian but I have an xlv. I emailed him some measurements to see if it would fit. He hasn't had a chance to reply to my email so I figured I ask if you remember what your measurements are. This is what I sent him:

Ok see if this makes any sense.

from were the floor of cock pit starts to base of foot well is 16" Deep
Its 27 inches wide from left side to beginning of cup holders outer wall
Cup holders are 7" wide so a total of 34" wide if you measured from left wall to right wall if you measured from the top of cup holders.
It is 9 1/8" from the lip of the back cup holder (closest to foot well) to the foot well if measured from top of cup holders (foot well is at a slant)
The foot well measured 13 1/2" tall by 5 1/2" wide at top
And its 22 3/4 from floor to the dash (under steering wheel) its at lot higher if measured behind the dash area.

Thanks

Brad
