I heard somewhere on this forum that the more airspace a woofer has, the less power it will need to power it to a certain extent. So my question is...I built a box with two seperate sealed chambers that are 5.6 cubes of air before woofer displacement. My subs are the new 15" Alpine Type R's. Should I get an amp that produces slightly less than their RMS because of the huge box size? Thanks in advance for help.

In a sealed box, the air inside the box acts as a spring of sorts. When you give that sub power, and it tries to push outward, the air in the box along with the suspension of the sub itself limit it. Air can omly be compressed so much, and having a smaller box will limit the movement of the sub to an extent, and a larger box will allow more movement.
I would say to get an amp that matches the subs, and tune it down a bit. It would **** if you felt like changing the box and then the amp wasnt sufficient.

Good point...thanks for the info.
