Regular Cab Truck, Not Enough Cab Volume for Great Bass?

I have a 2000 GMC Sierra reg cab with 4 elemental design e3.8s in a sealed box behind the seats powered by a soundstream reference 10.0. When the doors/windows were closed sounded pretty good, open one window the bass increased significantly, open both windows it got even louder! Open the doors and the thing would pound!!!!!
I think the the cabin causes canselation somehow. Couldn't figure it out why so just lived with it till the subs gave up
