hmmm remove the floormat and you should have 7 inches if you can press the box into the seat, fiberglass the top of the box and do downfire and you can fit something with more mounting depth like a CDT sub that should sound better than LP... You can always cutout the floormat later to fit around the box..
Evenwithout fiberglass that CDT sub might fit if you use 5/8th MDF for the top of the box. Just an example.
My Titan has about 9 inches in the front and goes down to 5 or 6 or so in the back and I have full side subs. I think you have the space for something better if you are careful.
Other options would be to raise the seats, or even just use a rubber spacer where the rubber pad is not to keep them from coming down all the way in the front that would give you a couple inches up front and then you could forward fire some beefy 8's would would probably be better than shallow 10's.
