ported sub-floor

[randeez 0]

ordered a xcon 12, waittingggg for it to come in. I figured i would get started. should be finished this weekend with atleast the subwoofer box, trim panels will be a while, until i figured out what amps i'll be using

car is a 2007 acura rdx tech with els audio- i'll be starting a build log as i get into it more

conservative measurement of spare tire well, 7"high/ 27" diameter yields me over 2-1/4 cubes+box extends above well i should be in the 2.5-2.75 range when all done. i'll packing peanut the whole thing when i get it done. tuning will be sub 30hz depending on enclosure final size

i was fine with bringing up the floor level, i could almost make due without raising the floor below but the black hard foam pieces hide some brackets/wiring/etc removing them didnt gain me much

 

using the trim cover pieces as template, seat brackets will probably be hidden behind amp rack.

 

 

board pretty flush with floor will be the underside of the port, box will be be another 3-3/4" higher (port+top), port will wrap around sub on each side 3"x6.5" (twice) for 39 sq inches of port area per optimized enclosure drawings on ssa site. port layed out on plywood, i've got it layed out in autocad, port(s) are about 45" long. roughly cut the center section out i'll clean it up with router when i get the port walls in i wanted to peek inside spare tire well, going to use some wood down inside speed up glassing and fill some of the larger flat areas

 

 

taping off sucked, but here's about where i ended up for the day i need to remove the hold down bracket for the jack/spare and finish taping it off, and probably run another layer just to make sure it's all settled

Are the whole ports going to be inside the enclosure? If so how much space are you going to have after port and sub displacement?

[randeez 0]

yea, that plywood will basically be mimic'd another 3" higher , sandwiched between the two sheets will be the ports and more open section (the area that is cut out of the board shown above) about 15"x25"x3" = about .7 cu ft in addition to the spare tire well. 

 

the ports are inside the enclosure, but doing my cu ft calcs i'm only measuring the airspace, not gross -port- wall thickness- sub displacement (sub will take away from my measurement but i'm winging it for the most part lol)

"Winging it" is exactly what we like to see here.

Sub is on the way, fiberglass mat, cloth and vinyl ester resin is getting picked up Tuesday to get that going.

I'm going to be recessing the sub, is the outside measurement (12.5") good for carpeting/vinyl covering or should I add a little more to that?

[randeez 0]

bout done with all the wood working, got to recessing the sub had to cut a few rings out- it'll be 1-1/2 down from the top hoping i wont  need any more room for the excursion. Waiting on glue to dry and ran out of day light. the edge against the hatch i may cut the top sheet the same arc but as close to the port as i can and have that edge at an angle going up

Waiting to see more

thanks, it's gettin there, baffle is pretty much done. 

gotta try n sneak out of work sometime next week and get started fiberglassing- which i hate but atleast it's nothing that has to look good 

 

[wannabang 13]

Oh wow!  That looks great if it's all air-tight!  I was trying to guess as to how it would end up looking.  Very cool idea.  Are you gonna put some kind of fencing over the port, just so random stuff doesn't fall in it, or a border around it so stuff doesn't slide over it?

[randeez 0]

i've got some ideas in my head but yea there will definitely be a grill over the sub and port just havent nailed down exactly what i'm going to do.

I want to finish it off very boring, oem style carpet over top of all of it, which means another layer of 1/2" or 3/4" ply to cover everything trimmed out to all edges neat and clean- hide the grills (or grill) in that layer. 

but be able to pull that cover off, underneath have port/sub exposed with either painted or textured leather/vinyl in case i want to show it off so that top will have a lot more work put into it 

 

my s/o drives this car most of the time, i want to be sure she can randomly throw whatever she wants into the back of it and not have to worry about damaging anything, so the grill will be overkill

wtf double post, edited second and and first one went away

 

anyway, haven't done much been working, put a wedge where the port exits. contemplating putting one where it enters but I may cut the port down if I was way off on my calcs and the ports to long. it's at 55" now as the opening in the enclosure has the same area 3x13=6x6.5 if it's going to stay that long I'm going to add the wedge. if not I can cut the bottom out of the port making it about 44".

 

got some fiberglass suppies- 2 gal vinyl ester resin, roll of 4"x110yrd chop mat 1.5oz and 5 yards x 50" wide of 1708 biaxial cloth. should be able to bang most of it out this weekend

Very cool design, clean work!

random pictures, fiberglass crap, i picked up some 12 gauge/8 conductor wire too, i was looking for 12/6 for running into the doors but couldnt find any cheap. i havent stripped any of it out to see how many strands it has

Hell yea!!!!

anddd it dont fit.....recessed rings are a little tight to let sub fall in with the gasket i should be able to massage it to work pretty easy.

and the ring for the sub to mount to is to loose for my liking but i never glued it to the others so its easy enough to re do

[Randal Johnson 544]

Cool Install

thanks!

 

fiberglassed this past weekend also, no progress pics i did it in between rain- which sucked even more cause it took forever to cure between layers, ended up hitting it with the heat gun. box has about 5-7 layers throughout, painted the inside of it with some rubber coating 

i'll take some of the box tomorrow if i can get home early enough. 

[wannabang 13]

WOOOOOOOOOOH

about 5 minutes with the belt sander and the sub OD fits snugggg, there were two noticeable spots that werent quite round, fits perfect now. gotta grab my buddys router sometime this week, and another sheet of ply  , to redo the ring that the speaker will actually mount to. I am also going to reinforce it a little bit more. the ring that recesses the sub it really only about an inch larger than the cut out- i'm not really comfortable with that glue joint having my sub hangin off it.

 

pics outside, didnt realize how crappy cell took pics inside

Box about done, I think the fit is to tight to wrap in any kind of material though. Started filling screw holes and scratches to paint.

Stole some wire from living room tower knukoncept 12/4

Wiring both coils out of enclosure I will prob drop it on amp @.5 ohm at some point

[Lee Carter 150]

very cool box.

I'm dyin to drop it in and see if it sounds worth a damn

but then I'll probably have to take the whole box back out and flip it over to get the sub out, I thought about tapping two opposing mounting holes so I can thread in a larger bolt/eyelet into the basket to pull it out
