Alright so i decided to make a sealed box. On the adire site, i found 3 different sizes. One is Q=0.95 another Q=0.707 and Q=0.6, 25.5 liter, 54 liter, and 88.5 liter.
Which one should be the best?
Also, how should i connect 2 subs? Right now ive got 2 old kicker 4 ohm subs. How should i connect them?
Thanks.
Sorry for asking so many questions

Have you read any of my posts?
I already answered your question.
4 times VAS.
So look up the VAS on the Adire site, multiply by 4 and you have the volume for an Infinate Baffle.
If you want sealed, just use the VAS.
The VAS is 151 Litres, which converts to 5.3325147 cubic feet
4 times vas is 604 litres or 21.3300586 cubic feet
And Viperoni has recommended a 1.5 cubic feet box
And Shockwave has all but cut the wood for you.
Get a free program for speaker design off the net.
You will notice there is no one correct design.
They all just produce different results.
I WILL NOT have a box in my trunk, so I spent $800 to have a completely new rear deck made from wood, fiberglass, and Vinyl so I could mount the drivers on the rear deck and completely seal the trunk off, there by using the trunk as a HUGE (infinatebaffle) enclosure. My entire trunk is usable, and I get the most "audiophile" sort of response.
I say this is the best sound because it plays down to 10 hz FLAT.
Sealed will roll off too much, and ported will not play below the port.
FLAT is also not really flat.
IN a far field listening position, which the car is, you want a slope starting louder on the low end and sloping down (in db) to the high end at about 1.5 db per 3 octaves.
