Ok, not to be a thread theif, how many DB's could you potentially loose if you mounted both of your subs inverse? And how much effect will it have on SQ?

If you have a great driver and a well-built, properly sized enclosure, then loss of SQ should not be a concern.  There are some tight situations where the only way to build the sub is to invert it because of space limitations...in SQ systems.  IIRC S. Kephart has something like that in the front of his car, and he's all about SQ as you all know.  And if using enough power, loss of db's wouldn't be an issue either.  I've not heard of any complaints where someone inverted two of three (or so) subs, had the air volume corrected to compensate...and noticed a reduction if db's after doing so.

I'm of the opinion, however, that in most cases of sub inversion, the purpose is to show off the rear end of the driver.  That's not SQ talking.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Ok, well thanks for all of the input everyone, but i got kind of lost and that diagram while it was cool, totally went over my head. I am building a fiberglass enclosure and just for sh*t's and giggles i inverted them to see how it would look and i just wondered if theyd put out the same and stuff. Here is what i did *****NOTE: The enclosure is NOT finished yet, that shot is with ONLY resined fleece**** So, if I installed these two just like this, would there be any problems? Thanks!!

If you have both of them inverted then you can wire them normally at the woofers and just switch the main positive and negative wires at the amp.

When you're done, if you want to hide the wires better you can use one or two of the holes for mounting the woofer to run the wire through. Make sure to seal it up though.

It'll probably flex, and not sound right.  Throw some fiberglass on it until it doesn't flex, then use some body filler to get it smooth.

so does wiring one woofer out of phase make a difference on the load the amp sees?? ( 4ohm load with drivers mounted normally , will it still be a 4ohm load?? )

No, it'll be the same load on the amp.
