I am going to be building a box soon, and sort of wanted the subs to angle in towards each. By doing this, will the waves cancel each other out, or will there really be no difference?

This is just my opinion, but if i were you, i would get the subs and have a ported box built to your subs specs. If its built right it would very hard, or if you really want the subs to angle you could have a bandpass box built to your subs specs, do you have the subs yet, and what kind are they if you do?

what is the reason for having them face each other? space, looks? what kind of vehicle are you putting them into?

I am going to put them into a 2001 S10 Xtreme Xtd Cab.
They are 2 12" Rockford HE2's
Powered By:
RF Power Series 851s
And the designs would just be for looks.
What do you think? I did not really want to port it

Yes, it is possible, I have done it numerous times my self.  You can face the subs exactly towards each other.  Wire up one sub the regular way, and the other one out of phase.  That way, both cones are moving in the same direction at the same time, and you will not get any cancellation.

Not exactly the best idea. This will work if the box is ported only, otherwise you will only have output from one sub at a time, the other sub will yes be out of phase and cannot get it's wave into the cabin. The Rockford He2 is a pretty good sub but generally prefers a sealed enclosure. Any properly constructed enclosure built to the appropriate airspace for the sub and the vehicle will play loud and clean. True that a ported box can sometimes play louder, but in most cases a sealed box yields way better results, a moderate angle towards each other is perfectly acceptable, I imagine this was what you were asking.

Top Secret, I can tell you but then my wife will kill me.

I am very familiar with RF Subs and they do definitely have to be placed in a ported box. Now what I am wanting to do is not exactly have them facing right at each other, but making a fiberglass angle of maybe about 25-30 degrees. Would that be okay?

With that angle, you can definately leave them in phase.  I plan on doing the same thing in my new project.  In the corners behind the seats facing the trunk opening, but angled 30 towards each other and up.  Good luck with your project.  Posts pics of your work in action, and your finished product.
