Thank you, it did help :)

that link should help you figure out port length and whatnot.

As for a sealed box, they can get plenty low, but they give you more of a range of frequencies the sub will play, but wont be as loud.

As for making a 4 cu.ft. box fit, you can make just about anything fit, just depends on how handy you are.

hope this all helps.

hello everyone, i'm new to this forum and i need a little bit of help already, well first i will introduce myself to everyone, some of you people might know me from Caraudioforum.com and from Elitecaraudio.com well my name is Justin and i'm from Chatham Ontario Canada, well here's my question: i bought 2 12 Infinity Reference 1230W subwoofers Infinty Recommends a Sealed Enclosure that is 1.25Cuft per sub with 1inch of fibre fill on each side, or a ported enclosure that is 2.00Cuft per sub with 1inch fibrefill on each side with a port of 12.26inch lenth and 4inch diameter, well i want to go ported but i would like to know if i can just make a 4.00Cuft ported enclosures and put both subs in it since that each require 2.00Cuft each anyhow so 2.00Cuft + 2.00cuft=4.00Cuft so will it be okay to put both sub in this box? if so would the port lenth and diameter change?????

Thanks for any help and i hope i made sense..

PS- i have a 94 Cavalier i did some measurements and i just want to make sure a 4.00Cuft box will fit, i don't want to build it and find out if won't fit..

PSS- if i get stuck building a sealed enclosure, how low can a sealed box go? and can i make it smaller then factory specs so i can get more of a punch??
