It will be for a 12" Kicker CVR sub. I am building separate boxes for each. It will be a sealed box. These are my main concern questions, if anyone knows some info that would be great, thanks.

-What is the recommended volume?

-Is it okay to have many angles in the box or will it not work as good if it were flat edges?

-Can the subwoofers face eachother or will the force that each create distort one another?

-Is it better to have the speakers facing the rear seats or the rear end of the car?

Mine point to the floor.

what are you putting them in? a car truck or suv?

There are several books out on speaker design. Radio shack even has one. It just depends how technical you want to get and how much room you have to work with.

they are going in a 96 civic coupe.  I already have a box but it would have sit infront of the race stut and would take up so much more space.  I want to separate them 1 on each side how trunks have a pocket where the rear lights are I figured I would utilize that space.  I am having trouble making them flow with the trunk and have atleast 1 cubic foot of volume.  I wish I had 10's rather than 12's.

the bigger the box the better its gonna sound and you should maybe port the box to and i think your back seat folds down right? if so fold it down and it will sound better

nah not true.  Ported boxes need about twice the space and they have a harder hit but loose sound quality.  Sealed boxes have tighter bass and the best sound quality and require less space.  I wouldnt fold the back seats down.  I dont do the whole pounding bass and rattling thing this is for the full spectrum of sound that the other speakers cannot hit that low. 

well you shouldve said that you wanted it to sound nice but not rattle your car to death i was just trying to help a brotha out but besides that im the total opposite then you must of my truck is dyna matted and i had 4 l7 15s in a sealed box and they sounded ok but when i ported the box it sounded like i added two more i was just saying from experience   ;D  you dont have to call me a lier   

Kicker cvr12 need 1 cu. ft. min and 4.6 cu. ft. max for each sub. I always put them in 1.5 each. In my experience they seem to like sealed boxes better then ported but they will work in a ported the box is just going to be bigger. Kicker speakers aren't really known for being for sound quality. If you fire them backwards it will be louder, but in return is gunna make the rear of your car rattle more. The shape of the box shouldn't make much of a difference just as long as you get the air spce correct. As far as the woofers facing each other just don't get them to close give them a couple inches for movement. You are always going to get some cancellation when the speakers aren't mounted on the same plain , but it is only at a certain frequecy.

I moved to a wedge shaped box that would fit 1 speaker behind the stut facing the rear end of the car angles up some.  Then I said screw that if I ever need to put something in the back and need the seats folded down to put it I cant because the speaker box will be in the way.  Now i'm just going to slap together some boxes and all it a day.  They will be in the trunk corners facing the front of the seats.  If I dont like the way it sounds or I think its too much i'll change the location or just use 1 sub.  After all its not a show car its for function.  If I wanted it a show car I would get custom boxes and everything but I just want a good sounding stereo and parts that are more fuction than show.  After all any sub has to be better than none right?
