Couldn't you just make a "rectangular" box and fill it with polyfil/acousta-stuf and that would eliminate the standing waves too?

Polyfill can have some effect on dampening standing waves inside an enclosure, yes.  Lining the walls (or at least the back wall) with genuine acoustic insulating foam (like this or an equivalent) is actually a much more effective solution for correcting standing wave problems.

I just build a sealed slant box for my Honda. It took the better part of a day. But I am a drafter, so I drew it in AutoCAD first, so it was easy to figure the angles. As for tools, I found that the circle jig for a Rota Zip works excellent for the speaker cutouts

Thanks for the tip. I have the Rotozip complete toolkit, but never really used the circle jig yet. It can make a perfect clean circle easily with just giving the center point and the radius. I will use it in my project surely.
Also by filling the box with Acousta Stuff, will that help get rid of free standing waves in the event I have the back wall parallel to the front wall(where the sub is mounted)?

as far as glue goes... the best stuff is construciton grade polyurithane (i think thats how you spell it?) This stuff is twice as strong as liquid nails .. and it has tensile strength..

Thanks for the info. I am going to definitely use polyurethane . I've read that on some very good speaker building sites and even on parts express's how to build speakers section. And you said it to and you swear by it, so I can bet its going to be really good and I am going to use it too.
