Gas tank out, sub box in?

I have one 10" kicker L7, I have my amp turned way down it hits harder then any 10 I've ever heard. The box is ported on the passenger side and I have a 500 watt amp.

That's similar to what I want to build, except for me one ten isn't going to cut it. :/ I'm in need of bone-rattling, earth-shaking bass lol. I have a 500 watt Bazooka amp, but I'll probably need a bigger one for three twelves, correct?
