Subwoofer boxes

[PsykoGamer]

I've looked around online for awhile and noticed there is a guy on ebay that is selling these custom 3000gt subwoofer boxes. I'm just curious if anybody has bought one and was just curious as to if they actually gave decent sound and look as good in person as they do in the pictures posted. I guess what I'm wondering is if they're worth the $200+(including shipping) he's listed them for.

I have to admit, it doesn't look too bad. I do think its quite expensive, and I prefer to make my own boxes. But, for what it is, looks like it drops right in so it would certainly save you a headache of measuring everything and cutting it to spec. Can't comment on the sound as my boxes were always where the back seats should have been. :)

[PsykoGamer]

well for as big as that back hatch area is I'm not surprised a custom box such as this can cost so much as it is. I was definitely thinking about avoiding the headache aspect of putting another sound system together whenever I get another 3000gt

Actually that price is fair, If i wasn't wanting to keep the option of storing my sunroof in the back I would probably buy one of those boxes.

[SL00ƜGT0]

Yea, thats a good price. I build my own boxes and if I built one like that for someone I would prolly charge something similar. As for the sound, the idea is good but I cant attest to it as I have not had heard it.

[PsykoGamer]

hmmm ok that's good to know they aren't selling at such an astronomical price as opposed to what other people would sell them at. Just gotta wonder how they sound and hope they aren't too hollow sounding

[Vishnu]

I have one. There are a few things wrong with it that he doesn't mention. If you have a little bump over where your rear tire is, the box sits a little higher than the ones with a flat trunk, giving you less internal space and mounting depth. Another issue is that if your sub has a thick lip, it tends to hit the trunk hatch. I had Kenwood DVC subs that stuck out about an inch higher than the box and the door would not close. The seller's "fix" for it was to remove the cover over the spare tire (which made the box not sit very securely) and I decided to just get thinner subs.

So be careful buy it as you will have to find matching subs that fit just right, you cant just do anything you want with it.

If I can find the pictures I took when I first noticed the problem I'll post them up.

[PsykoGamer]

alright that'd be cool thanks. Yeah my 3000gt had the little nub that went up the middle of the spare tire to keep it in place. My solution for adding a full subwoofer box was to put a brick on both sides of it under the box to keep it stable lol. Yeah I know it was a rigged thing but at least it worked and thumped pretty good lol.

[colt45 gto]

it looks SUBstandard :lol: and where would you put anything after?

the best idea is to buy or make one that sits behind the seat so you have atleast some room to put your rubbish!

[PsykoGamer]

well I think the back seats make more of a trunk then the actual trunk in my opinion lol. It is just so small you can't even fit a small asian person back there.

[Vishnu]

Flat tires are your worst enemy. And you need a decent amount of strength/flexibility to maneuver it in and out of the car.

[black98-3k]

well I think the back seats make more of a trunk then the actual trunk in my opinion lol. It is just so small you can't even fit a small asian person back there.

My Asian person fits back there just fine. Of course she is a woman and flexable, but what else would you want from a gimp? LOL

[the_duke]

I don't encourage the lost of a trunk for subs. Simple thoughts: do you have expensive rims on your car? If you do, do you have AAA? If you do, then I would pull the spare tire out and build a box to sink into the spare tire area. Then you have a place to put things ontop of your box.
The other idea is to build a box on each side of the trunk, allowing room in the middle.

Both of these ideas are done extensively in 300zx's (which I own one) so that's where I pulled these ideas from. I cannot confirm the acoustics of either, but you still have trunk space..

[sketch]

back. seat. delete. seriously, who is going to fit back there? i'm only 5'5" and girls shorter than me had trouble with leg room sitting directly behind me.
back seat delete for subs actually gets you more cargo space, IMO

[PsykoGamer]

yeah I think the car makes for a better 2 seater anyway. What is sad is I bought brand new seats for my 3000gt 2 weeks before I wrecked my car and was just waiting for the brackets and sliders to come in. Got my money back for the sliders because they were never shipped and I needed the money.

[green-lantern]

I don't like how much room it takes. Subs have come a long way and I don't think you need that much room for a good sound.

[locplayer1]

here is mine it is a little less than 1.5 cubic ft still have some trunk space and I don't have a spare tire thats what cell phones are for.

http://i908.photobucket.com/albums/ac286/locplayer1/0330001806a.jpg

and here is the amp rack it sits behind the rear seats amps on 1 side power distribution and crossovers on the other side

http://i908.photobucket.com/albums/ac286/locplayer1/0916091152.jpg

[PsykoGamer]

wow I must admit that looks pretty damn good. What brand of subs/amps are those? Did you make the box yourself?

[SL00ƜGT0]

here is mine. the fabric is not secure on it yet but you get the idea.

[PsykoGamer]

yeah that's not bad either...are those 10's or 8's?

[SL00ƜGT0]

those are 8's. Im running dual Focal 21wx Be's. I've hit 140db with em, just need to refine the box and i should be set. all the amps are hidden in between the box and the back seats.

[PsykoGamer]

well that's pretty cool. yeah I think I had mine bolted to the backs of the back seats. Didn't think I could do it any other way I guess. For me I guess 8's are too small and I have to go beefy with the 12's lol. I had a great box that I left in Cali...now I have some piece of crap in my Mustang that doesn't seem to allow me to hit as hard.

[locplayer1]

wow I must admit that looks pretty damn good. What brand of subs/amps are those? Did you make the box yourself?

Those are Db Drive subs and amps, I built it myself here are some build pics

If you want to put a number to it the last show i was in it hit 139.2 but I don't have much power going to them and the car is setup for SQ not DB, Wish I had a set of Focal Utopia's

[2fnloud]

I am more curious about the 4 devices right behind the rear seats. Are those Aura bass shakers?

[mb3000]

When I bought my car it had that exact box, with 2 10's and it sounded annoying, drilled out the holes for 12's and the sound was so bad I wanted to cry.

I dont drive many people around except for my girlfriend, so I took out the rear seats and put a nice ported box there. I value the minimal trunk space available vs. rear seats, but thats just me.

This is what my setup looks like:

is that stable enough to stay where it is under its own weight?

just curious - did you test it out having it fire backwards at all?

[locplayer1]

No those aren't bass shakers those are Db Drive Euphoria Cross Overs for my front and rear speakers.

[mb3000]

Yes, I cut a piece of 3/4 inch plywood for the base then secured it with little feet things (to support the open space that you would normally sit in) then covered it with carpet and just put the box ontop of it.

The box has never moved around or anything and I have been driving with it installed for around 5 months now.

And I would have, but I'm a tall guy and I sit with my seat all the way back so it wouldnt work. Although I do know that the box will fit if it is sat down, it just didn't allow me to sit the way I am most comfortable.

[ras463us]

I purchased this unit from an Ebay seller several years ago. I LOVE it. fits great and sounds even better. Easily removed if needed and really doesn't take up much of the hatch space. I have already modeled it in solid works and have thought about making a few of them. I am not yet a verified seller, so I will not post up a price or take orderes, but if you would be interested in one let me know. That way I can atleast see if there is enough interest in making a batch.

Here it is installed

I used a similar box for a few years and loved it! Went with a different setup in the red car when I did the rear seat delete. I think this box and the corner box are the most practical, in order to be able to use the hatch area for storage, and keep the spare tire.

[DeadOhioSky39]

If you don't care if it is specifically made for your car then just start looking on Ebay or Craigslist. I found a nice box on craigslist for $25. Great shape, nicely built.

I've got one kicker L7 12" in a ported box. I have the back seat folded down behind the drivers seat and it sits there facing rearward. It's impossible to drive a stick with someone sitting behind you anyway so i just said screw it.

Replaced the door speakers with some polk/momo 6.5" and the rears with some Alpine 6x9's when the stock ones started going. Sounds good enough for me and it wasn't stupid expensive either. I'm also not much of an audiophile though when it comes to telling small differences from one speaker to the next.

[DJ_X_Factor]

I'm personally using the Ebay box that fills the rear hatch area and couldn't be happier with it. I'm running two Kicker CVR DVC 12's and haven't really tuned them out yet and still hit 141dB with that box. Not too shabby...and I could care less about trunk space...my Stealth isn't my DD. Now yours is a DD, I wouldn't suggest the box because its simply not practical; but if you're going for a good look and good sound, then it is a very viable solution.

[Flasher]

I agree, to keep "some" trunk space is always a nice option to have. I went with the single/sealed sub set up - 1 12", actually kept my entire spare tire area intact (the spare isnt in there) and used the side pockets for extra storage. If i were to lift the floor panel you would see just the well for the spare tire. http://i154.photobucket.com/albums/s250/91sts/DSC04718.jpg http://i154.photobucket.com/albums/s250/91sts/DSC04720.jpg http://i154.photobucket.com/albums/s250/91sts/DSC04735.jpg

O_O

wow, nice clean install!

[jba3]

I have one. If you get one, make sure to put some kind of padding on the bottom; the box likes to "thunk" when the car bounces a bit, especially if you have a stiffer suspension (even sport mode on the stock ECS). I've been too lazy to pull and pad mine, cause I mounted the amps to the rear of the box and I'd have to unhook all the wiring. :(

It's worth the money if you dont need the space. I'd like to go to a behind-the-seat setup, but I'm not sure how dual 12s would work with that. I regret not sticking with my SmokinVR4 10" corner box.

why don't u just mount it so it doesn't move around? It not only won't move around and make noise but its safer, think if u were in an accident your sub box becomes a projectile rather easy.

If u get in an accident, that sub box isn't really going anywhere...mine sits pretty damn snugly...maybe each is made slightly differently?

[jba3]

It sits very, very snugly on all the horizontal directions without needing to be attached. It also sits on top of the plastic trays, so there's not really much to attach it to. The box doesn't visibly "jump", it's just an annoying sound to hear it tap against the plastic going over bumps; like a squeaky seat bolt or squeaky door panel. I'm OCD about that kind of thing. :)

[locplayer1]

ah i see, just use to work for a shop and mounting was very important on anything custom for sure. but I say its your stuff do what ever you want to

^ Agreed. Very clean, and flows very well with the interior, I'm quite impressed.

Everything fits nicely in one very compact spot and I still have all my trunk space. BTW that a 12" sub not a 10".

[Spyder]

2 12" might be to much for this box, the air space in it its very limited. This was an ebay box and even with the 1/2" mdf he used (yes not made of 3/4") to originally make the box you are limited to about .9 cubic ft of air and thats before sub displacement.

My box is divided in 2, amp side and sub side. On the amp side I have the wires that need to connect to the amp and the amp itself. The sub box it self its about .5 cubic ft which is the minimum for my sub but I also have some poly fill in there.

A good single 12 or 10 should be more than enough. You could also do 2 8" subs that was my original plan and easier to work with.

Yeah, I'm just trying to work with what I already have on hand, if it sounds like crap, I'll go to 10s if I need to. But I don't want to deal with selling the 12s and then buying 10s if I don't need to. Never should have sold my SmokinVR4 10" corner sub and gone to the dual 12s. :facepalm:

[jba3]

(double post)

[scoob]

well youve probably seen my build before but ill add it to this thread, 1x 12'' sub in a custom made mdf and fibreglass bos in th ewing section ,works great and enough base :-)
http://i927.photobucket.com/albums/ad119/sco1gto1/106_7000.jpg

[Spyder]

Do you know the mounting depth on the 12" subs you have?? Im 99.99% this box will be waaaaaay smaller than what they need. I had 2 10" kicker cvrs before in there and they sounded "fine" when you were sitting up front. As you got closer to the back it sounded bad, the subs were taking the box apart plus the resonance was horrible to begin with.

The kickers I had in there were 5-9/16" in mounting depth and they were like 2mm away from hitting the back which is already waaaaaay close. I say they should be atleast 1" away from hitting the back.

That's what I want to convert mine to. Do you have dimensions for the box? I found rough ones online but they didn't make sense ... the size of the speakers was larger than the dimension of the panel, so I think it was wrong. I have dual 12s, I'm hoping to mount them facing rear and the amps on the box behind the seat, or vice-versa if I need to since the angle behind the seats gives more surface space to mount a 12 on. Not worried about peak sound quality, more about trunk space.

I'm about 99% sure he is using a shallow-mount 12 in the above-mentioned setup. That's why a lot of people go for the 10" solution with a box like that, your airspace is quite limited.

[Spyder]

Yes it is a shallow sub, 3.5" deep in the 12" version and 3" in the 10" version.

For shallow sub I would recomend the SI BM, RE SL, or JL TW5.

How about the Polk MM series. Granted 4 1/2" depth is not as slim as other shallow subs out there but with a carbon composite basket, helps make them one of the lightest subs out there.

Too bad they didn't utilize a neo. magnet.

[Spyder]

I have their MM components which I like, they do use Neo magnets. Im still deciding which sub to get from them.

Really? As I looked up their mounting depth, it looked like a typical magnet to me.

[Spyder]

From polk.

When you first pick up a MM series speaker, you may wonder why it's so light or why the magnet is so small. The answer: advanced technology. First the MM Series uses a Neodymium Magnet Structure This premium material allows us to replace the traditional bulky ceramic magnet with one more compact and much lighter.

[2fnloud]

That is their MM components. Nothing is mentioned on the sub woofer page. And this magnet doesn't look like a Neodymium magnet.
http://www.polkaudio.com/images/site/mm/back.jpg

[Spyder]

Or maybe is just on their component speakers IDK.

[n2nsanity]

it looks SUBstandard :lol: and where would you put anything after?

the best idea is to buy or make one that sits behind the seat so you have atleast some room to put your rubbish!

i actually have a custom box i made for an escort like 12 years ago that fits right behind the seat, lol
fills in the space perfectly, have to lock the rear seat with force tho

[Spyder]

Anyways i just ordered 2 10" eclipse subs.

[2fnloud]

What ones did you get?

[Spyder]

I got the SW8010

I was thinking of polks MM component speakers and their neo magnets at the time and not the subs oooops =]

[2fnloud]

I am curious to know what size box they need. I was looking at Eclipse subs but they look heavy and I was under the impression they need larger boxes.

[Spyder]

The 10"s I ordered need 1.25 cubic feet sealed minimun IIRC. They are pretty big for 10's so that's where some of the size for the box comes from.

[scoob]

most subs tell you what size is required when you buy them. 1.25 is a big box for a 10''.most 10s' are .95 and 12s' are 1cft. you can also add fibrefill to a smaller enclosure and it tricks the sub into thinking its in a bigger box (stupid subs hahah)

[green-lantern]

Mine needs to be recovered and I really need new subs but I love this box. I have a strut bar going through it now. It helps making the car more ridged and makes it real hard to steal. lol

Funny thing because my 12' needs .5cft and my 10"s needs 1.25cft minimum.

Well since I sold the eclipse amp I had to redo my sub box. Not done yet, I was just doing a test fit before I finished screwing it all up and a few touches.
http://i99.photobucket.com/albums/l285/murcielagojdm/99/2010-11-28161632.jpg

Also since I already had the stuff there and had some more time...
http://i99.photobucket.com/albums/l285/murcielagojdm/99/2010-12-07195443.jpg

I made a brand new box :-D its a single 10" all mdf not particle board like the others, 3/4 inch face 1/2 inch the rest not 1/2 particle everything, and sealed, glued, and screwed not held by staples like the others. I ended up with 3 boxes, 1 carpeted and 2 not carpeted. It was a PITA to do a full carpet job on this box, not doing it again. Next time I'll just fold it behind the edges and staple it.

End result

Are you selling the spare boxes? If so, how much for 1?
