Good lord. First off. You don't have a 400w amp. Quit saying you do. If its not RMS value, its merely a gimick and you're a fool for falling for it. Max -> RMS Conversions can be anywhere from 1/3-2/3 the power. It all depends how good the amp is.
Fuck, I mean just fuck.
I put in "alpine type e" into google. First link was to Crutchfield which gave box volume suggestions. Suggested box size is 0.8-1.7ft^3. Your box, 15x15x8, is 1.042ft^3.
And then can you guess what I did? I put "how to build ported box" into google. Here are some of the first page links for you since evidently you couldn't find them:

Impossible to find? Horseshit.
Edit: As Pernilongo pointed out, the sub isn't even designed to be in a ported environment. Ugh, just go buy some Boss or Legacy units and put them in a bandpass box and show it off to your friends. That seems to be what you're looking for.
