Well, here they are. Check them out and let me know what you think. Bear in mind that this one is for my personal P5 so I made certain changes to the design to accomidate the grill that I chose to use and the woofer I chose to use. I can make them smaller (not protrude into the cargo area as much) if desired. Anyone interested who has not been following the story on these should do a search on P5 custom enclosure(s) to get the skinny. Also, I know I'm gonna get this one right off the bat, so yes you do have to relocate your jack. In the album there is a pic showing that all I did was loosen the bolt for my spare, push it forward and to the passenger side as far as it will go, re-tighten the bolt, wrap my jack in an old t-shirt and wedge it in the well between the tire and the rear wall of the car. This does not buldge my trunk floor at all. My jack tools (stock lug wrench, ect) also fit under there with no problems. Take the plastic jack cover and store it in your closet, and BAM!! .3 extra cubic feet of airspace. I did choose to mount mine with a screw through the back of the box into the jack bracket. When you look at yours, you'll see that there is nothing behind it, so you can screw into it without fear of drilling into something important.(unless you use 6" screws) Even with it semi-permanently mounted, I can still easily get to my spare. There's a pic of this in the photo album. Questions and comments are welcome, and just search the old threads on this for ordering and pricing info.
Hope everyone likes them.

Actually, just search by my user name and you will get all of the threads in there, the other way misses a few of them. Oh, wanted to add that the woofer and grill in the pics are not included with the box. (somebody always asks) And also wanted to add, this box is one of the better sounding boxes I have ever built, and hits harder than the box with two tens that it replaced. Check out my other album in there to see pics of my Accord that I'm trying to sell.

wow dude, that's some good work! i wanted one like that when the p5's first came out, but the shop wanted $800 for the damn thing (it was mostly fiberlass i think). i said i'd think about it...

that is cherry tho! hope you get a bunch of orders.

Cyberglitch

Very nice work man. Looks very nice indeed, kinda work I was looking at getting as well with asking shops around here no one did fiberglass work (just found 1 today will ask them maybe this afternoon tomorrow for pricing etc.)

My only question is could you do 1 for each side both being 12's? Also coming from the top stock plastic piece how many inches does it extrude out so I can get a rough idea? Talking about plastic lip above the jack area.

Will defiently have to sleep on this as it's a very nice deal here, specialy if you could get 2 sides in there or someway to get my 2 12's neatly in there.

markmurray77

I also have 2 12" but that looks really good, maybe you could make one for the other side.

ZZOOOMM

That rules!!! I hate that big box in my trunk. I would love to install my 12' in the side panel.

maxxbling

I have had this question quite a bit, but the two sides are so different (shaped) that it would be near impossible to get them to mirror one another and also have them have the same airspace. I'm not saying that it couldn't be done, but once you do this on both sides, you're not really saving yourself any space, you're just changing the shape of the space that you have. Doing this would somewhat defeat the purpose of having a space-saving enclosure. My suggestion would be to :
A. sell one 12" woofer to a friend.
B. use the money to purchase a "maxxbling box."
C. insert remaining 12" woofer and enjoy.

My only question is why do you use stuffing in your enclosures when you are tight for airspace? You do realize that fuzzy stuff does take up airspace, and hinders the airflow(at least that's good in a ported box) right? And I know there are theories and what-not on how that is supposed to improve the sound, but me and my friends who install stereos for a living never really agree with puttin stuffing in there. It sounds fine without it, and plus it fress up more airspace.

Other than the whacky stuffing stuff that **** is fresh. I really like how you molded it to the rear panel like that, and barely protrudes into the trunk. How much time it take you to assemble on of these? While I admire the work, I could never go for this setup. Lots of people like stealth, and then there's lots of people like me, we don't care how much room you need we're gonna sacrifice it for the bumps. SO for the stealth, clean lookin install enthusiasts this is the ****. But for the all out db monsters and what-not, heh we'll keep fillin our trunk up. How does is sound, and do you get pretty good bass response outta it?

Actually, the stuffing makes the woofer act like it's in a larger enclosure. I've been using them in all my sealed boxes for years. You should only fill up about 50% of the space, over stuffing it will not help.

Sweedenhouse

OK, well that's cool. I just don't understand why. Most of my knowledge is with ported boxes, very little with sealed. But how does the stuffing that takes up space, make it think its actually a larger space?

maxxbling

The stuffing in the box is a very subjective thing. It is meant to make the woofer think that it's in a larger enclosure than it actually is. The reason this works is that the air inside of a sealed enclosure acts like a spring for the woofer. The smaller the airspace, the tighter the spring and the less freedom of movement the woofer has. As the woofer moves, the air inside the enclosure is compressed and rarefied (stretched) very rapidly. The air molecules in the enclosure bump into all of these dacron fibers which slow them down, thus making them take more time to react with the woofer cone as if the enclosure were larger. As you said, this does not apply in a ported enclosure due to the port acting like a pressure relief valve. It does work, but it is not a miracle cure or anything. It only makes a slight difference. More than anything, I like to use it to break up standing waves inside of the enclosure to give a smoother sound. That is to answer your question, however I am not tight for airspace. The enclosure is 1.27 ft3, and the woofer displaces .128 ft3 leaving 1.142 ft3 for my woofer that has a recommended sealed box volume of .7-1.0 ft3. It doesn't sound any different than a good 12" woofer in a convertional wooden enclosure.
The enclosures do take some time to make. I'd say if I was able to work on it steady from start to finish, about two days.

maxxbling

the rule of thumb is to use 1 pound per cubic foot.

Sweedenhouse

Heh well thanks blueLEDz, but my box is staying how it is. If you could see the insides of its pretty fresh, with mulitple braces, staggered ports going through braces, and angles to prevent wave cancellation. Maybe I'll get motivated enough to pop a sub out and take a pic to show, but it sounds great at any volume level. Like I said am not an expert at sealed enclosures, hence my newbesque question about the stuffing. But with ported, I'm pretty sure I have solid grasp on how to make a good sounding box. Thanks for the input, and maybe I will stick some **** on the walls, just for one of those "gotta try it" things, heh but prolly not.

Brotha - all I can say is nice, nice, NICE!!

And - I'm realy glad to see someone who's NOT just talking **** about what they're gonna do. Not that it happens often, but once in a while we get all hopped up on someone doing something original, and it never pans out.

I think it's been like 2 weeks or so from concept to completion for your box - excellent.

They look really great, too. Funny - you were able to get well over 1 cu/ft out of that - while my MDF box for the same area takes up MORE hatch space, doesn't look half as good, and only has about .5 cu/ft inside - and that's before the sub displacement!! (this is why my sub sounds like ****, and has low output - I need a nice airy box, then hopefully I'll be able to tell I have 500 watts back there).

Due to some of my own requirements (we discussed this by email, remember?), I think I'll probably attempt my own 'glasswork first. But if I find it too frustrating, I'll be looking to talk to you again for sure - a box like this is exactly what I need, and your design is exactly what we P5 owners have been looking for - a convenient, space efficient, well-built, great sounding (taking your word on that!) sub enlosure.

People - BUY THIS GUY'S BOX!

I hope you sell a TON of these, man. I would absolutely consider eBay if I were you - do a Dutch auction for like 20 or more, explaining that each one is hand made and will be fabricated upon reciept of payment. Set a price and I'd bet you'll get it many times over.

Great work, Maxx.

Thanks for the kind words, and I'm glad everyone seems to like the enclosures. Keep the questions and comments coming. I haven't gotten any orders or e-mails (except hihosilva's) or anything yet, so I'm wondering if there are any other reservations that people have because I had at least 5 people that said that they wanted one as soon as pics were up. I was trying to aviod doing this over e-bay to avoid all of the fees and what not, but I may have to do that just becasuse the interest that many members said that they had does not seem to be here. I'm going to wait another week, and if I still haven't recieved any orders, the enclosures are going up on e-bay to see how they do there.
