Thats 75 square inches of port area, pry make the port more like 3.5 inches wide

how about this...

Longer the port a little. Also note that calc doesn't take into driver displacement (.19cf i think) which wil throw shit off a little.

No box is good enough for a Q IMO

which box? the second one, after driver displacement would be around 3.9 cubes tuned to around 29...at least that what I'd think. Why would he want a longer port?

whats that mean

well I tried using the subwoofer tools box caculator or whatever but I put in the length to be 26" and it keeps automatically puttin it back to 31.5". If anyone could help me out with that, I have L-26" x W-32" x H-14" tuned between 28-33Hz. It could probably go an inch wider but I made it that size to be able to get it in the trunk.

Sorry if I'm a noob but where is the link to that box calculator thingy?

I meant shorten it. No real need to have it tuned that low..

Forget the online calcs and have someone do it for you that KNOWS what they're doing //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif ... I would like to figure it out myself so I would be able to help someone else that is in my situation...

I was going to post this in your forum, but got carried away so I thought I would start my own.

read thru it and see if you get what I'm trying to say.

Fooling around with an online calculator is just going to waste your time anyway, he is correct.
