Phase 1


Gluing and screwing the plywood together. The sides and rear baffle will be 1 1/4" thick; the front baffle will be 2". Despite the fact there are screws holding the two pieces together, they get a little help from yard implements. It will be a few days before I get enough glued together to begin Phase 2.

Phase 2

So this is what was done today. With the plywood sheets glued, its cutting and assembling time. What you see here is one half of the build. There will be two of these boxes that will slide into Dennis' van. The board leaning up against the box is the baffle. The box is tapered (difficult to see) - with the top is shallower than the bottom.

A shot of the port hole. These cabinets will be tuned to 36Hz. You can see some of Dennis' IXL's in the background.

Tomorrow I will work on bracing, port and baffle. I'll throw up more pictures tomorrow on the progress.

If memory serves, Dennis already sealed/hardened the roof of his van and has removed a lot of the molding from the rear section.

I'm not sure what Dennis plans to do actually. I handed him some samples I received to try out. Since he's going completely active, if they don't pan out, he can always swap them for something else.

For those of you who intend to build a bigger box, make sure to use plywood instead of MDF. Everyone thinks MDF is the way to go because of its density.

Wrong.

By itself, MDF has very little structural strength, and it is strength you need when dealing with the stresses caused by high output subs. Standard Birch plywood is fairly cheap and half the weight of MDF, yet is *so much stronger* its crazy. A good combination to use (to keep your costs down) would be 1/2 Birch and 1/2 Fir. If you want to finish your box with paint or something like that, then use a thin layer of MDF, which is what it is good for.

birch unfortunately happens to be twice the price :(

mrogowski
06-07-2008, 09:04 PM
hmmm really Ill have to try it

I say half and half since Birch is a softwood and Fir is a hardwood. If you can afford it, go all Fir. Use 3/4" Fir for your average box, including baffle, provided you don't plan to recess your driver.

I notice folks using Spruce 2x4's as bracing. This is wasteful, since Spruce is a soft wood and a 2x4 offers little structural strength lengthwise. It is also wasteful using it for end bracing as well, since it's lack of density will allow your baffle(s) to move before it fully compresses. Don't bother with it.

Threaded rod also offers little strength outside its immediate structural perimeter. If you want to use threaded rod, use two or three "stepped" layers of plywood to increase the perimeter strength. Either that, or use threaded rod say, every 8-10 inches or so.

Give me a minute to put my flame suit on...

Eh? I got 3/4" Birch ply (both sides rough) for $25 a sheet. Are you thinking about the solid stuff?

The baffle is done up along with the port. I will only add the one window brace you see here. Just waiting for the glue to dry before adding it.

cheap birch PLY is ~$40 a sheet around here. That's for the low ply stuff from Lowes... Hell MDF costs me more than $25 a sheet! :crap:


Back on topic. The build looks good so far. Cant wait to see it done. I also look forward to my own big M5A build...but cant afford it right now.

Sorry to hear about the high prices man. Consider using 3/4" Fir - expensive, but one layer is all you would need.

looks cool but why didnt u center the port??

mrogowski
06-09-2008, 09:18 PM
I thought of that, but I wanted to take advantage of the side and back panels to save on wood, complexity and time. Frankly, it looks like ****, but will be totally transformed once it is finished and in Dennis' van.

DBDesignsElite
06-09-2008, 09:54 PM
I can tell you this. Your going to kill that van, trust me. I also suggest you run the hu outside of the dash. I have done all i could to keep the dash from moving but it just doesn't work. lol.

I guess the way you plan on running the source units it shouldn't be a problem.

Looks good so far.

mrogowski
06-09-2008, 10:29 PM
That's a good point actually. We planned to have a back area to place the batteries and other stuff. Do you think having the head unit back there would minimize the issues? There will be a back panel sealing this area off.

DDeitz
06-09-2008, 10:35 PM
i'm keeping my old unit around just in case i need it. and nice box sir :D

You won't be saying that when its time to hoist the boxes into your van :laugh:

DBDesignsElite
06-09-2008, 10:39 PM
Yea that would work real good.. I just removed the CD5000 i had in the dash and will run it in hand for comp/demo. Im sick of trying to get that dash to sit still.


Also keep a eye on the weld locations that attach the top part of the door to the main part. They WILL break. lol.


Cant wait to see this done. If it does what i think it will do prepare for some Damage!!

mrogowski
06-09-2008, 10:45 PM
Thanks for the tips! I guess we could run a second set of pre-outs to the back end for the "loud times".

The van has sliding doors on each side. Are you referring to the slide track?

I guess re-weld. Just keep a eye on it. You will know when it happens. When you go to close the door and you push on the top you will hear a bad "Click" sound. That and the front windshield seal lol.

All and all you know its going to be a awesome flex fest thats for sure!!:D

thanks :D and what year is the caravan your running that has a denso 300 in it ?? im assuming your sig is referring to the caravan, noone could build a 300 amp for mine. Ohio did 200 that was the most i could get.

Its a 2000. The Denso was rebuilt by a local alternator shop here. They modified the internals and changed the case. Its a lil bit on the longer side and a ***** to get installed.

They also had to flash something in the PCM for it to run properly. Ill get more info on the modification if you need it.


Hell if you dont plan on running AC in the vehicle just remove all that crap and have someone fabricate a location for a second alternator if need be. I know its possible.

DDeitz
06-09-2008, 11:57 PM
yeah i know i can do it that way, but i kinda like my ac in the summer (for now) Was just curious how you did it, cause i would have loved to have been able to get a 300 instead of the 200:(

DDeitz
06-10-2008, 12:06 AM
well iraggi can make me a "300" but i didnt trust him after what i had read online. All the other places i called could not even come close to 300. I ended up with ohio gen, had not read anything bad about them.

So the second one was completed and we managed to get both of them carpeted. We threw them into Dennis' van and found things to be a bit tight unfortunately, especially at the rear. I don't have pics of them in the van yet though...
