Dayton Audio RSS315HO-44 12" Reference HO DVC Subwoofer
I have an 800w amp (400w/channel x2 (dual-mono) @4ohms) that I want to use with this sub for the purpose of live sound reinforcement. Is it possible to run each of the voice coils on their own channel bi-amp configuration? What type and size of box could this work in?
This sub will work fine bi-amped like this. If you have separate gains for each of the channels, you will want to use a meter to adjust them so that the outputs are the same. Some people have a scope they can use to adjust the signal to exactly the same level while others will use a simple voltage meter to adjust. If the gains are not separate, they will be the same anyway so it won't be a problem.As far as the box goes, the wiring configuration really won't make a difference. There are several questions above that answer "the best enclosure" question.For live sound reinforcement, I tend to prefer ported boxes and this sub will work in either a ported or sealed set up. For your application, I would likely go with a 1.75 cu ft box with a 4" port 10" long.You could also go with a much longer port and tune it by cutting and listening until you get it where you want it. Port velocity doesn't become a problem even at 30" long so you have a lot to work with.If you want a smoother, more musical sound, go with a 1 cubic foot sealed enclosure and keep it simple.

What is the optimum box size for 2 12" HO dvc.
I have 2 of the dvc 12s going into my car. They will share the same space and have @2000 watts rms. looking for the best possible SQ.
This sub is designed to perform well in small, sealed enclosures. If your space is at a premium, 2 of them sharing a 1.0ft³ sealed enclosure will yield the "optimum" Qtc of 0.707, and an F3 frequency of about 47Hz. However, you'd be hard pressed to fit two 12" drivers in that box. If you give them 1.0ft³ each, for a total volume of 2.0ft³, the Qtc drops to 0.564, and the F3 would be 45Hz or so. I'd recommend simply building the box according to the space you have available, perhaps 1.5ft³ or so. You'll get a good result for mobile audio without a great deal of change in the F3 throughout the range of enclosure volumes up to that 2.0ft³ size.

optimum box size... magnet included? or magnet volume separate
took a class in san pedro ca teach mentioned that a woofer might ask for 1.5ft box but you have to factor in the magnet displacement... what is the bext sized sealed box for this woofer? 2.12 plus magnet or 2.12including magnet? i want it to be happy in a small a box as possible...
The Dayton Audio RSS315HO-44 is designed for small sealed enclosures. I would recommend a cabinet that is 1 cubic foot (which should net to around a 0.8 cubic foot cabinet). Your F3 won't change much with a larger enclosure and should be around 43 Hz.

what is your recomendation on using this driver in a bandpass configuration. i would like to run the port from the box to the deck lid inside the car
For a decent bandpass enclosure, build the subwoofer cabinet to 0.7 cubic feet (chamber 1) and the port chamber (chamber 2) to 0.4 cubic feet. The port needs to be 4" in diameter and 17" long. The port may extend from the box to your deck lid.The lower f3 is roughly 40 Hz, and the upper f3 is 106 Hz.

Follow up box question
I have a box I was using for some other drivers. It is made to run them inverted with about .62ft3 per sub not counting cone area. If i use this box, would it be better to cut out the wall in between the 2 air spaces? Would acousta-stuf help?
Your volume of 0.62ft³ would be fine for this driver. It wouldn't make an appreciable difference whether the center divider is there or not. With Acousta-stuf or poly-fill, I always recommend simply trying it and experimenting. When you find the amount of stuffing that sounds best to you, that's the "right" amount.

VC's in series?
What are the specs of this woofer with VC's in series?
the voice coils ohms will sum in series , the parameters for box size will remain the same, some dampening problems occur if only one vc is used ,or if you try to use two different amps to drive each coil,and make sure the amp can hold the load in ohms.
