Most generic pre-gabs tend to be 1.75cu ft, however to be properly tuned, you need the T/S parameters and/or tuning frequency.
Look around on the net, you may get lucky. Lanzar does not have it as a download on their page. Maybe a call to their customer service would net you the information!

What puts out more power when subs are ran in series or parrelall


Depends on your amp, ohm rating of your sub, box dimensions and ports or chamber size, size of vehical.
Run the subs in 2 ohm if the subs and the amp can handle the demand. Look for the Qtas of the sub. You'll loose 1/2 of the control to stop the sub if you run it in two ohm. You'll blow the works up if any part of this equation isn't up to the task of a 2 ohm load.
If your budget, space allows, run it in 4 ohms at the max RMS of the lessor (sub and or amp) and add more amps for more subs for more effect. A very well designed box/enclosure with an average component list can make a wonderful sound. It will usually beat a bigger budget sub/amp setup in a generic box. Theres lots of science that goes into a great sound. Dig into it and have fun

What to do


well i don't know your budget, but if that's not really and issue, right now at best buy, alpine type E, 10" subs, peak is 750w and rms is 250w, each is 129.99. Alpine type R, 10" subs, peak is 1500w and rms is 500w, each is 199.99. These are the best subs i found at best buy. You could sell your current subwoofers and purchase those, and you'd save space and still get the lows you want. Goodluck

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

What type of enclosure for audio bahn aw1000x


I used to be an Audiobahn dealer and can help you with the box. However I can't find specs on that model in my records or on Audiobahn's website. If you email me (dynami28@charter.net) the Theile Small parameters for the subs I can give you more exact specs. The box should be ported (Audiobahn doesn't recomend a sealded box) with about 2.5 cubic feet, made of 3/4" MDF. Here are some generic specs that should go well with that particular sub.

Air Space (Cu. Ft.) 2.4

Port Size (Inches) 4 x 6.25

Tune Freq. (Hz) 39

Size of boxes


Wow you are in luck, I used to be an Audiobahn dealer. Designing sub enclosures is my fulltime job. So here you go.-
If you are looking for sound that is very smooth, and has a very low end shaking everything setting off car alarms. You will need a PORTED BOX that is 3 CUBIC FEET FOR EACH SUB WOOFER. It actually calls for 2.7cu.ft but after you add speaker displacement and bracing it should be at least 3 cu.ft. The port can be either round or square made of plastic or 3/4" wood respectively. My port suggestions are dependent on how much space you have. The shortest round port might make some noise (too much pressure!). So think about that first. Anyway the short port is 3" diameter and 15.5" long. The longer port is 4" in diameter and 28.25" long. The rectangular wood port can also be either (port measurements are inside diamensions) 3" w x 3" w x 18.5" long (short port) or 2 w x 10.5 h x 48' long. The second longer wood port is recommended most but will take up a lot of space. The fact that you have to subtract the port volume from the box makes for space issues in cars. Also the second wood port sounds better and won't make much wind noise, but takes up .75 cu.ft worth of space. So in plain english your box will have to have an internal volume of 3.75cu.ft. An example of this could be made of 3/4" thick MDF, have 1" x 1" internal bracing and measure (box dimensions are external and assumes the use of 3/4" MDF) 12" h x 18" w x 30" deep. The port is an integral part of the box fitting inside. I'm sorry I can't provide any drawings to make things easier. Now this box size is one that I ran through a computer program I use. So it is not the same as the manufactures recommendations. I will list those as well.
The second box is an example using a round short port and also uses 3/4" MDF, 1 x 1" bracing, the 3" dia x 15.5" long port, and measures 12" x 18" x 24" externally.
If space is an issue try checking out the information below. -I got it from Audiobahn-
If for some reason it doesn't show up or you need assistance let me know. Good luck and enjoy your new setup-I'm sure you'll be happily disturbing the peace soon!

    Soundstorm amp


    I wrote it in my solution to the original question.
    You are shooting for a 4 ohm load.
    so a single 4 ohm driver, a dual 2 ohm driver, or (2) dual 4 ohm drivers will do the trick.
    Bridge the amplifier @ 4 ohms to get the most power.

    huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

    1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

    2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

    3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS
