A local business has just become a dealer for RE Audio, and they're using my Jeep as a demo vehicle. This is going in a Jeep Wrangler and will replace the back seat. Let me know what yall think. Its for 2 RE 12" XXX:
2.7 ft^3 per sub, tuned to 32 Hz
port size is 2" x 8.25" x 12" for each sub

WOW, that port is WAAAYYYYY too small. I'd give them each 2.7 cubes NET w/ AT LEAST 40 in^2 of port. OR tell them to make it a common chambered box, 5.4 cubes NET and like 80 in^2 of port (to make it easier on the port length b/c of a larger box!) peace

I tried that "WinISD Pro Alpha" for the first time to see what it thought the port size should be, and I thought it seemed a little small. Im close friends with the 2 guys of the business, and Im actually going to construct the box myself this weekend. I was going to put both sub in one chamber, but they only have 1 12" XXX on hand right now (actually its in my friends truck right now), but Im heading down to Destin next weekend, and they want to put the word out a little. This way, if I have 2 chambers, I can use just one sub for now, and add my own to it later. Itll look funny, but Ill just patch the other hole until I get back. So I need around 40 ft^2? Let me work the numbers real quick. Thanks for the quick response too.

Hows this sound?
Port = 3"(H) x 13.33"(W) x 34"(L)

Don't have the time to figure out what that'd be tuned to, but much better on the area.

Just to let you know, I'm saying you should do AT LEAST 30-40 in^2 EACH! peace

This would be right at 40 ft^2 if I did it this way, Im actually gonna use the space b/w my box and the rear of my jeep as part of the port, so this should work out nicely.

The port inside the box will be 22", and then there will be 3" of air b/w the box and my rear door, and then this will travel up the other 12", and this should be tuned to 32 Hz. Hows that?

"Sketchup 4.0" by @Last Software

I highly recommend it for anything 3d, its quick and easy, I got it free through the college of architecture, but I think its around \$500 for the public.

Wow. Hold on there buddy. The shop is using your vehicle as a demo car but you have to build it yourself???? Normally they build it...

And yes for a demo vehicle they are going to want to call re and get the best recomendations for that vehicle and equipment being ran.

Run the ports all the way across the bottom.

automotivations
03-02-2005, 04:24 PM
Whys that?

If I do that, I can keep the length the same, and change the internal dims to 2.5" x 15.875" (just under 40 ft^2), and then itll go all the way across the bottom, and still be tuned to 32 Hz.

look at the drawing you have, then look at one with the port all the way accross the bottom. Which one looks like it'll move air free-er

You think itll make a difference, maybe with port noise some.. less interruption I guess, sounds good to me. Ill sand all the edges down on the port too, Im getting the entire outside of the box sprayed with speedliner (bedliner) and it seals up nicely, and only \$50 and takes about 5 minutes to spray (I love this stuff).

Okay, I think this is it. Im going to Lowe's today to get some mdf and stuff. What's the best, or easiest, way to make some cushions for this seat? I was thinking of just getting something thats close to same color as my seats, but its gotta be somewhat durable, and wrapping it over some foam, but dont know how I want to attach it to the box yet.

i really hope you decide to brace the 'seat' area. its going to break rather quickly with your weight + internal pressure while only using 3\4" mdf my friend.

automotivations
03-03-2005, 01:38 PM
I highly doubt it, the piece that separates the chambers along with the sides and the ports act as braces. Are you talking about compressive forces or lateral forces? Ive worked with 3/4" mdf for the last six years, and the screws and adhesive will do more than enough, not to mention the bedliner that will cover the entire exterior of the box. But thank you for your concerns...

req
03-03-2005, 01:42 PM
i mean the fact that thats going to be a huge box, the car is going to be going over bumps, and my 200lb 6'2" *** sitting on it while its pumping at 2.6kw with only 1 internal brace is kind of daunting. imagine 2 people sitting on it.

screws arent that stRong. neither is wood glue.

the box might stay together on its own - but lateral and verticle forces created by the car going round corners, and the weight of the passangers PLUS the compressive forces of two ****ing XXX's arent going to make those seams happy.

automotivations
03-03-2005, 01:48 PM
Well I have the lateral (horizontal) forces taken care of, b/c the box sits snug in b/w my rear fender wells. As far as compressive (vertical) forces go, I think it will be okay as well, but if it will make you happy, I will add some braces for you... if there is any wood left over, which there always is. Let me know when youre coming into town so we can test it out.

Quick question: Any suggestions on sub protection (cover of some sort)? I dont want people jumping in and out of my jeep to destroy them.

req
03-03-2005, 02:05 PM
id prolly make somthing out of 1\2" plexiglass - and offset it from the box with some nice 1\4" aluminum rod

but i would prolly invert them for a 'show' install.

then theres no need for cone protection.. but you gotta worry about people taking wires out and ****. so maybe solder them?

automotivations
03-03-2005, 02:09 PM
Invert would be cool, gain some air space too. Is it okay to mount sub like that, facing straight down? Ive seen it done in installs before, just never done it myself.

yea, no problems - just reverse the polairty (or phase) of the subs. + goes to - and vice versa. otherwise they will hit on the 'off beat' or whatever. and you will gain like .3 cubes too :)

but on a side note...

Let me know when youre coming into town so we can test it out.

was that supposed to be sarcasm? :rolleyes:

Don't necessarily need to reverse the polarity. You should actually try their polarity both ways (reversed and normal) and see which one integrates them with the rest of the stereo the best. There is no "set" polarity that they need to be wired to.

ive never had any problems with always going +

but its much eaiser to play with in a inversed install anway.

What amp(s)? Im eventually going to use the RE amps, but they wont be done for another 2 months, so until then, I need something else. Im looking to push about 1500 to each, so Ill see what I can dig up.

automotivations
03-07-2005, 02:42 PM
Alright, built it this weekend, but changed it from 2 subs to just one, so now its around 5.2 ft^3, still tuned to 33 Hz, port length changed to 30" overall inches instead of 34". I also adjusted the angle of the seat, b/c it just wasnt comfortable during mock up.

req
03-07-2005, 03:27 PM
braces make it look MUCH stronger!! but id of put some sort of design in the back headrest area, wrapped in coushin, and vynl... maybe cut out some RE logos in the MDF between the two seats? that would be cool.
you might be able to get a bench seat from the junkyard off an old truck (for the seat coushins \belts for really cheap. then just upholster them :)

quick question, did you say that the port is going to use the 'rear of he jeep' as part of the physical port length?

im not too sure about that. you will prolly want to end up fiberglassing the back and connect it to the box... it would leak and not be very effective if im understanding you. but correct me if im wrong.

automotivations
03-07-2005, 03:42 PM
That is the idea, never tried it before, but Ill see when its all hooked up in the end. If that doesnt work too well, Ill just add a sheet of mdf to the back to extend the port. Im gonna do some designing on the box before it gets sprayed, just dont know what yet. Either adding some cushions on top of seat, or putting down foam and then covering it w/ something.

req
03-07-2005, 04:16 PM
i would most certainly test it out before it gets sprayed.

and take a trip to the junkyard. you might be able to find some nice pre-shaped coushins (even if they have terrible upholstry it can be redone)

why not use the factory seat material to cover your cushions when you make them or you could get some covers that mastercraft or bestop makes for all the seats so they match just an idea

Yep, borrowed it from my buddy, I think Im gonna wait on the XMX, but might just get a XXX when I get the money figured out. Ive already decided to use the covering from the original back seat, trimming the foam down so its not so bulky, or might just use something else under the seat covering like some polyfill or pillows for just this weekend down in Destin. Ill be pushing 1342.1 watts to it with an MTX 81000d amp (borrowed also, waiting on RE's amps). Ill let you know how it sounds when I get it hooked up tomorrow, and Ill post pics when its all installed.

please dont give it a name. its been scepulated over and over, and noone really honestly knows - that can proove it.

but the 'uberwoofer' that we here at ca.com have dubbed it - will do 4"+ excursion and is like 3" deeper than a current XXX - and for some reason it dosnt have a pole vent :)

must have vented thru the sides of the new basket design. hmm. cool lookin bugger tho. looks gigantic.
