I have 2 12in JL subs in my regular cab so I'm limited on space. I have foam in both of them, but I'm wonderig if I take the foam out and cut 2 2in holes in the top of the box will make them hit harder. Any opinions?

You cant just cut holes and expect it to hit harder. A ported box has to be much larger than a sealed. And ports have to extend inside the box (so far) depending on the frequency its tuned too.
