Box specs for sub

you dont need a cap, im pushing 2 10s with 400 watts. As far as the box, how big is it? how many cubic ft does it have. Once you know how many cubic ft it has, then you can go out shopping for subs. I went with Image Dynamics bc i heard good things about them for the size of box i was running. .5cu/ft of air per chamber. So that was my starting point. Then it also depends on what kind of amp you have and at what ohms that amp is stable at. Let these guys know what size the box is and what kind of amp you are using and these guys here wont let you down. I am very happy with their recommendation

Ported box? I believe that you have a C5 although I did not find mention of it in your other posts.
Most ported boxes start around 1.5 cu^3. That is a pretty good sized box especially in a c5. Most people run sealed or some sort of custom build out in vettes for multiple woofer set ups. This is mainly due to limited space in the car in general and the small amount of air space available in the rear center console area.
I am just barely going to get .70 cu^3 out of my sealed box using .5" birch for a 12" sub install.
If you are going to use this box you will have to provide air space (at least dimensions of the box) and constuction (IE how thick the wood is) as well as port length and measurement across the port itself. Hopefully then we can give you some sort of recommendation on a sub.

should i just measure dimensions? I don't remember the equation or whatever to figure out the cubic feet?
btw: right now I am running an infinty 600 watt amp. also another question...what is the difference between single and dual voice coil subs?

Take measurements for the box (IE length/width/height) on the outside of the box. Then take a measurement to find out the thickness of the material it is made out of (most likely .5" or .75" MDF ) and we can then do the math to figure out your internal dimensions and then your air space. Great calculator here: http://www.bcae1.com/spboxnew2.htm
Then you have to measure the length of the port "tube" itself and then the measurement across the front, or if you wish the measurement around the port so we can hopefully determine where the box is tuned to (IE 28hz or 45hz etc etc) and make a sub recommendation.
If it were me I would buy a drop in box from www.subthump.com for a 10" or 12" sub in your price range and call it good
