12" Stealthbox

I'm trying to get a 12" Stealthbox that will fit on my driver's side trunk. But, the only one that I have found was from here http://www.subthump.com/acamarostealth.htm But it's constructed out of fiberglass and it's quite expensive.

Now, does anybody know of any other 12" Stealthbox available for the driver's side, and also is there an advantage in sound in the fiberglass setup?

Thanks

ill save u time and money.

do not get a 12' stealth box.
there is no way that thing has enough air space for a
good sub.:(

Why is it a waste of time and money? I have a 1.25 cubic foot stealthbox for a 12 in my room now, and ive got my setup all tuned out to maximize it. im also looking for a 1 cu ft one. they also make some subs that are designed for small airspace, some JL's and Type R's also..........not a waste IMO.

well if ur looking for some thing with tight bass that will be good.
but if ur looking for bone crushing bass i am saying u might need a bigger box.;)

Nah, I'm not looking for bone crushing bass. Just looking for some decent lows, but to a point I can feel the bass, too.

FWIW, im setting up 2 systems.............1 with a brahma 12 with 1000Wrms going to it in a 1.25 cu ft fiberglass stealthboxand another with a brahma 12 with 1200Wrms in a 1 cubic foot stealthbox.......I'm expecting both tight and bonecrushing bass, its the nature of the combo. should be installing the 1.25 box soon, ill let you know how it turns out. All im saying is that you can do it. ive heard a JL 12W6 in one and it sounded great....

What effect would too small a volume have on the sub's performance?

See if you can find a used box that BJ made (a member who posted here).

I have one of his 12" driver's side stealthboxes, with an IDQ12 sub, and it pounded (amp died, working on getting it fixed).

There is enough airspace if you pick the right sub and amp, that it will fill in the music nicely, and hit hard enough to rattle the spoiler. :D

There is enough air space if you take advantage of it all. I bought a fiberglass sub box that is a little on the small side for my taste. I'm actually going to try and sell it. It is for a 12" sub I had my IDV2 12 in it and it pounds hard enough to make the hair on your head move. If you like higher bass that pounds this thing would be great. You can contact me at zigcaddy@aol.com, I will sell it for a loss at $150.

I am currently making my own fiberglass enclosure that is going to be about .9 cu ft which is exactly what an IDV2 requires. I have spent several hours on this thing so far and it is going quite well. All I have to do is add more layers of fiberglass inside.

Do you have pics? And also, how do I know I can trust you?:confused:

Bighurt... If you're talking to me I don't know how you can trust me, but if you're interested in the box I have for sale you can pay via paypal and I think they will insure it so you don't get screwed. I just bought this thing myself, here is the web site the guy that sold it me showed me. The exterior of the box looks like that, though his pics are kinda bad. The top pick is not of this box it is a different box and the caption is not true.

Below is a pic of the box installed in my car. Note the front part of the trim needs to be trimmed for the panel to actually sit correctly in the car.

Just send me an e-mail if you are interested. I'm guessing this box is about .6-.7 cu ft.

FWIW, the pics that Y2KPewter linked look almost exactly like the box I have. So I imagine it would work just as well as mine does (very well).

Why not get the 10" stealth with a JL W6v2? ;) That thing would sound DAMN great!. I got a W3 in mine and it beats harder than alot of 12's...just need the right amp!

The biggest advantage to a fiberglass box is you can make a sealed up enclosure that will fit into that cubby area in the back and try to use up the maximum space avaliable. The downside in some regards is if you do it yourself it's not all that easy and if you buy it, well it's expensive for it's not all that easy to do.

Currently I don't know of any other 12" driver side boxes avaliable but I'll keep you in mind if I find any.

Well, make sure you use water to measure the volume when you are done. For .9 cubes it will need to fit: 6.7324675 gallons [US, liquid]

It sure looks like it would be easy to get .9 cubes out of that area but most times people are getting around .7 from that area or they aren't measuring the box right and saying it's bigger from what I've seen on the net.

I also have one of BJ's 12" drivers-side stealthboxes.
I have a JL 12W6 in it powered by only 250 watts (JL 250/1 amp) and it hits pretty hard.

I plan on filling it and measuring the one I'm building. The one I'm selling I'm guessing at it's volume. All I can tell right now is the one I'm making it real close to 1x1x1 foot on the exterior and I'm taking advantage of all the space up to the LR speaker. Gonna be a little difficult to measure the volume to 7 significant figures, but thanks for saving me the time of looking up the conversion. I'll attach some pictures once I get it built and if anyone is interested on how I did it.

I was actually thinking it would be easier to weigh it empty then with water in it to get the volume. I'm not sure my bathroom scale will give me to much accuracy though... lol

Anyway if someone is interested in the 12" box I'm selling send me a line cause I'll prob just put it on e-bay starting at $150 this weekend.

I'm just saying don't get bummed out if after you do it you aren't at the .9 cubes. If the box is 3/8" of an inch think that's around .2 cubes that will be taken up just by the fiberglass alone.

You'd have to get .2 cubes or so out of the LR speaker area for the other area is around .7 or so cubes if you still want to easily be able to remove it from the car from what I can see back there.

When building one my brother and I did I thought it looked pretty good until we later found out it was only .7 cubes. Surprised me for I thought it would have been bigger. The external volume would be around .9 though, oh how I wish external volume counted with speaker enclosures sometimes! :-)

forget about water, use packing peanuts.

Packing peanuts aren't accurate enough. I've had too many people misquote the size of boxes and to use a material that can expand and contract and also has room for air in-between it just isn't accurate enough or so it seems.

You can't cheat water, as long as it's measured correctly it's one of the best bets for an accurate measurement of box volume of fiberglass enclosures.

:rolleyes: why would it matter if it is off a little. is it going to make a difference of .03 in QTC, how about .05.... basicly playing a numbers game because a box might be off by 5% isn't going to make a difference. Trust me here, there is going to be no difference if a box is .85 or .9, there is going to be no difference between .9 and .95, simple rule of thumb with fiberglass.... once you are to the point that you measure the volume it is generally too late to change a lot....

Umm... no I'm not changing anything at this point. I just measured the volume of it using water and weighed it. It wasn't filled to the very top as I have a couple more layers of fiberglass to lay so I tried to account for that by not filling it quite to the top. But it came out to be .81 cu ft. For IDV2 12" speaker .85 cu ft is ideal. So I'm hoping that filling it with polyfil and that enclosure size it should have the SQ that I'm looking for. When I get it done I'll post some pics as it is the first time I've tried this and I think it is turning out pretty good.

I wasn't talking about the end result of how it effects the speaker performance but just that of box volume.

You saw it right here in this thread. He said he got .81 out of the box. How are some people saying they are getting a full cube out of it that area or .9 cubes of internal volume? Are they building the box differently or are they just not measuring it right. Could be one or the other.

Now onto speaker performance in the box. If they are only getting .7 cubes of internal volume out of their box lets say and they say it's a 1 cube box, well that's a 30% decrease in box size which is pretty big. I have seen some boxes that say they are 1 cube for that area (in Camaro's) but after looking at them they just don't add up to looking like they are one cube.

Mostly talking from the standpoint of the people that sell them and say they are such and such size. For the people building them on their own, you are right, once the box is built that's the size it's going to be.
