Box Size for 2 Arsenal 12's Ported

[james33440 10+ year member]

Well, I currently have 3 Ascendant Audio Arsenal 12's. These subs are dual 4-ohm and I have them wired to .67-ohm on my Kicker KX1200.1 amp. The amps loves it.

The box gives each sub 1.25 cu ft of airspace. The output is pretty good. I mean, it is a sealed box and some songs the output is tremendous. However, I would like for it to be louder. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I have a 2001 Nissan Altima. You can see my car here, http://www.cardomain.com/id/james33440 to get an idea of my trunk.

I don't believe that I can get a ported box for this trio into my trunk because of the actual trunk opening. I was actually thinking of doing a ported box for each sub but I still am not sure on whether or not it would fit with all 3 boxes.

So, I am considering using only a pair of my Arsenals in a ported box. The subs would give me a final load of 1-ohm so I can still use my KX1200.1 amp.

However, I am not sure on airspace requirements and what I should tune it to for daily use?

Please give me some opinions on box designs and tuning frequenices.

cutsheet if you're lazy:

if you can fit that you could most likely also fit this:

and get the recommended net volume.

if you have more width or height you could get the recommended size box and give up less depth.
