You should be able to download the owners manual for these speakers. The manufacturer will give detailed specs. on the type and dimensions of recommended enclosures for this particular speaker. If nothing is available to download, you could try to contact the manufacturer directly.

What is the cubic feet needed to build box for audioban 12

You can use this speaker in either a ported or sealed box. A sealed box would be smaller, (sealed box volume: 0.5 to 1.25 cubic feet) the larger the box the more base you will get. With a sealed box your amp has to work double hard as it would in a ported box ( 1.3 to 3.2 cubic feet) You will get close to double the volume in a ported box. Tuning a ported box with the size and length of the port will determine the hertz the speaker will play at.

I have 2 12 inch kickers and have a solid box in my mustang. would it sound better if it was ported?

Kicker speakers always require very large boxes (you're looking at 12 cubic feet for both), when ported. Ported boxes are very sensitive to box size, port tuning etc, so it's probably best to leave it sealed, as they are far more leniant, and sealed boxes are usually 1/2 size of ported boxes. You would get less bass when ported than with sealed (because ported boxes must be bigger to match the sealed ones).

If you wish to experiment with the bass response of speakers, download winISD, and put your speakers in, see what size boxes give you what.

Building a ported box for three audiofonic 12" subs but need spec

you need to find out factory reccomendations for airspace and port size. Many people with lots of experience building boxes still fail to do this and build good quality boxes, but for the wrong speakers.

Box recomendations

It depends on the size of the subs- 8z 10z 12z 15z? whether or not you port the box is up to you- a ported box is generally louder than a sealed box -as you are coupling and tuning the sound from the rear of the driver with the sound generated from the front of the sub- but the box is also generally larger as well.Then aside from your preference of ported/sealed you have to account for the recommendations of the manufacturer as to whether the sub/speakers are meant to be placed in a ported or sealed enclosure. Most 10 inch subs do well in a box that yields .75 cubic feet to1.0 cubic feet.most 12z do well in 1.0 cu feet to 1.5 subic feet and 15z do well in 1.5 to 2.5 cubic feet. I have a set of 15z that require 4.25 cubic feet per sub-so its important to look into the manufacturers recommendations. The easiest box to make would be a sealed enclosure-and the sound quality generally yields a tighter more accurate bass sound along with increased power handling capability- try going to rockford fosgate .com and look into the woofer box wizard its a program that calculates air space for whatever size box you have room for-hope that helps you-good luck

Trying to find out wat the watts are on a jlw3 12 and a jlw0 12

The JL 12W0 needs 125 watts RMS. Sealed box it needs 1.5 cubic feet. Ported it needs 2.5 cubic feet.
The JL 12W3 needs 300 watts RMS. Sealed box it needs 1.25 cubic feet. Ported it needs 1.75 cubic feet. I wouldn't suggest running these subs together.

What is the sealed and ported box volumes for the audiobahn dub 200 subs?

If you can access the inside of the sub box by removing the speaker, you may be able to measure the 3 dimension of each side of the enclosure.  1 cubic foot is 12x12x12 inches cubed.  That is 1728 cubic inches per cubic foot.  If you measure the inside dimensions of one of the enclosure sides as 10x14x8 inches, then that is 1120.  1120 divided by 1728 is 0.648 cubic feet.  Alternatively, you could estimate the volumes of each side of the box by measure the outside, figuring out where the box divider board is, subtracting the width of the boards used to make and then calculate.  Otherwise, I do not know the enclosure that that sub comes in.  Good luck.  Let us know how it goes.

i would go with the 801.And ithink u meant the 4501 not 4051.Both super power amps. competition stuff.your woofers are 4ohms dual voice you can series the coil on eaach woffer and use the two channels on the amp.they play at 2ohms.I think if you drop it down to 1 ohm you really be taxing you alternator that is series power.Yioou would need a special alternator.Even with them running in 2 ohms you better hav eat least a 2 farad cap.OR two batteries.. ! more thing don 't pump it up with window s closeed .you'll pop them.serious dbl. you be pumping.I'm jealous.Rating please and enjoy.
