It sounds like you have enough room to make a box identical to Seth's (he's using the same woofer). Go here Sandt38's B12 box

I would just copy his box, cut for cut. Nice little tutorial.

I like the lower tune and reccomend it. I run it at 1.9 feet (before displacement) and a 44 inch port, that has 20sq inches of port area.My tutorial that Luv pointed out shows a good portion of the construction (damn batteries went dead in my Digicam ) and gives a pretty good idea of the enclosure shape itelf. It is ~13 inches high, and about 2.5 feet wide, so it will easily fit. I can take some exact measurements of the enclosure tonight when I get home if you want... Mine will be a bit smaller however as I don't need the extra .2 feet for the sub displacement (mine is inverted) and my port is an external wrap around (aids in bracing too, great little bonus). I will be glad to provide a basic blueprint tonight when I have time to figure it all out for you, if you want...

I haven't heard when of if they are going to carry the amp. I assume so, because they have several 2003s listed, but I cannot say for sure...

As far as power, I have a Cadence Z7000HC benched at ~1700WRMS.

It is mad loud

sweet b/c i will be getting the gen xx hercules which will be 1600w at 1ohm so... but neeed them to get them in stock and they said the end of april is what hifonics told them. so hopefully soon.

thanks for the help
