You might find that the sub supplier has this software, and can recommend which type of enclosure is best for your application and calculate its requirements.

I'm planning to use Kicker Solo-Baric 8" subs due to the optional OEM small box size, output|weight, square=larger speaker cone size in a smaller space, and lighter overall weight.
Haven't decided between the L5 (300 watt consumer) or L7 (450 watt competition) grade Solo Baric's though. I'd rather just use 1 sub if possible.
Fabbing up some mounts for the subs isn't that hard, but figuring out correct positioning for optimal sound & "punching through" the cardboard spare tire cover are challenges to overcome.
These subs aren't the most effecient, but they do put out good SPL and in a car environment clear bass at very low volumes isn't really a concern (effeciency). Not sure how much volume/SPL you can really make with one 8" 300 or 450 watt sub. Plus the OEM box @ 0.66cu/ft robs some SPL due to the small size (you can make your own box larger box in the 0.8 - 1.0cu/ft range, but then you might as well by a cheaper sub then as any sub fits in this sized box).
Should sound great with the top up, but I want clear, loud, accurate, and 0 distortion @ 80MPH with the top down... which may require 2 8". Note I had HEAVY Dual 10" subs in my Mazda 929, and their weight+box weight threw off my handling & reduced my power:weight a bit. I'd like to avoid this in the vert.
http://www.kicker.com/ShowPage.cfm?f...enu=SUBWOOFERS
The other consideration is amp weight. I'd like to use one of the "all in one" amps with 4-6 full range channels+ 1 sub channel... and having gain controls & bass boost on each channel would be nice.
It's way too temping to move up to the "fully electronic tuning" offered in the mid-high end receivers, amps, & subs... and I'd like to ditch the analog pre-amps as well if possible, but that can get costly very quickly.

Here are some good links to pics of other vert installs. v8rx7's is probably the nicest imho and I have heard it. Also he has a very comprerhensive write up of how he installed it. Very good site. Sounds just like mine btw

sooo
it appears that boosted7 built his own box. i guess i will pm him and try to nab some info off of him.
i undertand i probably wont be using the sub to its full potential under the rear hatch and with a home-built box but like i said before. it looks like a couple of the guys have done it and i doubt they have all this high tech computer system gizmo whatever as was mentioned above.
i havent purchased my sub(s) yet so if need be i will buy the same as one of them have or something with very similar specs. i guess.

It really doesn't need to be that complicated. Sure, some sound quality will be compromised, but most of us wouldn't be able to tell the difference imho.

I strongly advise you talk to a professional about driver selection and box design. Any decent shop (i.e. not a budget chain store) will be able to do this for you.

hmmm.......
Nz you aint makin this process too easy for me. I am the kind of person that if i hear advice like yours and totally oposite views from others i get caught up in my decision process...
just curious about what you did (orhad done) with your audio system.

Just because someone has done this in their car, that doesn't make them an expert. The best advice I can give you is to talk to a professional. I am not an expert at this, which is why I have regular discussions with a very experienced acoustic engineer who also happens to be a home theatre enthusiast and likes to build his own speakers. I've also done a lot of reading over the years about sub enclosure design, so I know enough to know that if you want good results, it's not a job for novices.
I'm currently running 4" 2-way speakers in the dash, 6" 2-way speakers in the doors powered by a 200Wrms 4-ch amp and a Clarion head unit. I'm toying with the idea of running the headrest speakers from the head unit's internal amp but can't be bothered pulling the dash apart to get to the wires. Eventually I plan to add a 10" sub in a vented box, which will be designed by the above engineer.

Home-built is different to home-designed. I have installed quite a few stereos and can handle the fabrication of a simple sub box, but designing the box is a whole different matter. Most people have no idea how complex acoustics is.
The difference between a box sized at random and one designed using sub enclosure simulation software can literally be a doubling of the noise output, or a sub that can effectively only produce one note instead of a covering a range of frequencies.
Go ask your friend how he sized your box and port (if it's vented). I guarantee you there was very little guesswork involved. Any serious installer will be using software or staying as close as possible to any recommended sizes from the speaker manufacturer.

anybody on the board got this software?
I have heard of a few proffesional installers on the board, so they may have this software to make the super crazy sounding concert hall sub box nz is talking about. if you are lurking speak up. i want you to plug in some numbers.....
if not, i think i will talk tosokme people who ahve built their own and consult some audio places and the manufacturer of whatever sub i get and built my own... again, i just want some thump and a sub combined with new rockford speakers all around running off an amp and a new head unit has got to be better than the stocker equiptment that i am used to, so be it!
im not looking to enter competitions or have the sickest sub setup in the world, im sure this will far surpass stock and thats all i care about.
nz...do you by any chance get every last drip out of a pint at the bar.....every one?

The stuff is very common. Some of it is very expensive, some of it is free. Any serious professional stereo installer will have something used to design speaker boxes.

I used the head unit's "rear" pre-amp outputs for the amps and I used the "front" speaker outputs for the headrest speakers. this way I can also use the fader on the head unit to adjust the head rest speakers volume.
How do they sound?:
In my case .... I'm running so much power from my amplifiers. you don't even notice that they are there .... but then again, that is what I was trying to achieve.

13bpower did you build the box yourself
what dimensions is that box. i would have thought two individual boxes to be better than one/
Nz...i believe you, i just dont want to spend crazy cash ( which i dont have) on a custom designed install if i can figure out a way to reasonably do it my self, again, i know it wont be an optimum set up and again i dont really care. But i do believe you. Thanks for the input bud!

I do not remember the dementions, but it is one sealed box. 2 JL 10" W3(I think) subs. The airspace came out to exactly the recommended amount for the subs.
I all fits easily under the stock cover.

Well
the link i gave above has all the calculations required to calculate the internal volume of a box so i really do not see what the big problem is if that is all you think a professional needs to be involved in the process for. It appears to be some number crunching and some adjustment. Speaker companies most often give you the optimum internal volume of their sub. sooo. you measure out the size of the rear well and do the calculations for internal volume, crunch numbers and adjust and voila!
I have found numerous websites with equations on how to figure out the internal volume when building a box and everything.
So my question again, is what do i need the pro advice for?

I don't understand why you're so reluctant to even investigate something that'll cost little to nothing and add maybe 15 minutes to the time you take to buy the sub. You're making it all sound much harder than it really is. Buy sub, get seller to calculate ideal box volume, calculate dimensions required for that volume (just like that site says), build box.
