my 240 system project...

[Hellion240sx]

in that lsat pix you fbgls the inside of it? is that what your talking about?

[ayjay]

ya i fiberglassed the inside of the box for the top and bottom pieces... the only side you will really see when the box is all done will be the top piece, so the top needed to be super nice and smooth, that is why i fiberglassed the underside of it so that i could have the least amount of bodywork to do on the surface of the top piece (fiberglass is not smooth)

[ayjay]

threw the box & sub in today and ran it off a U-Dimension 8k.1 (800W rms)... never heard my sub sound soo good cause my previous box was not tuned for it whatsoever, had like 80hz roll off point :pface i think i got it tuned to around 40-45hz right now, cause it hits pretty much every frequency cept those in a song by techn9ne called "imma tell"... listen to it and you will know what i mean if you have a decent set of speakers/headphones hooked up to your computer

download here (right click, save as):Tech N9ne - Imma Tell

even my Grado headphones have a tough time hittin that frequency... but my sub should just pound that note, i wanna be able to hit the super lowww basssss that hits you in the junk! haha! so i gotta extend the ports by about 5 inches each one to get about a 30hz tune... hopefully this won't affect the other frequencies it's been hittin perfectly, gotta watch out for that -3db roll off

[ayjay]

oh and just so you guys don't get too excited, the box isn't done yet... gotta get some more fiberglass supplies and do some heavy bondo work, then do the carbon fiber... not too long before i'm done i hope, and i'll post mucho pics

oh and that techn9ne song has crazy bass but i only listen to it to test my system... download it if you want bass :pface (first time you'll hear the super low bass is between 30-32 seconds in)

[lofapoo]

C'mon ayjay don't leave us hanging

And yeah, Tech N9ne is very good for some bump and not too much excessive...ness (if you know what I mean)

[ayjay]

hehe i know... sorry guys i left my camera cable at my friends place, gonna go pic it up from her tonight and import some of the pics i been takin...

turns out the subsonic filter on the U-Dimension was turned up to like 40hz, apparently way too high for techn9ne :pface U-Dimension has these crazy elegant brass plates that covers up the tuning dials n' stuff, so i took it off and tuned the LPF and the subsonic so now i got a range of around 28hz to 150hz, and seems to have a fairly flat response accross the range... the DD sounds super deep and rolls out some nice smooth bass, i'm impressed so far, but the box is absorbing a lot of it's potential since the walls are really weak still so it flexes a lot...

pics coming soon.....

[ayjay]

some more pics... this thread is gettin huuuge, but hopefully it will give peeps ideas as to what you can do with a 240, or any car for that matter...

in this pic i was going to finish puttin first layer of fiberglass down on all sides, out in the sun so the resin would cure crazy fast... got jello? :pface

went all out and decided to start bondoing the top piece since i ran outta fiberglass supplies...

U-Dimension 8k.1, beautiful amp, good for testing purposes, just not enough power for my liking

i ran the speaker wire out the ports so that i didn't have to cut a hole in the back of my box quite yet... oh and you can see the beautiful duct tape and green tape holding the port extensions on... what you can't see is the hot glue i also used to keep the extensions in place

*edit* my DD installed in the box... this is with the hole cut in the box so the hatch latch could have somewhere to go... unfortunately the resin kinda shrunk the fleece a little and so now i can't get the hatch fully closed... gonna have to bust out the belt sander and go at er'

that's all for now! gonna go do some belt sandin

[Hellion240sx]

man ajay you are doing an insanly awesome job on your car!!!! im enjoying all the pix too.thanks, really

[ayjay]

thanks! but looks like i might have to modify my hatch a little to fit my box :pface obviously i'd rather mod the box before the hatch, but i don't think i can lower the box enough for the hatch to close properly... meh if i'm gonna go custom might as well go custom

looks like i'm done for a while though.. this thread is gonna be dug up in a couple months or so when i continue workin on the box...

peace!

[MECPInstaller]

The box is starting to look pretty good..... to bad its not as sexy as mine....lol kidding. I'm wondering who's going to finish first and how bads the box flexing, mine flex alil bit will have to fix that before i get new subs. Anyway nice job on the box keep it going have to love sanding..... sorry if directs anyone and this is for ya to aj afew new shots of the box and cdplayer My Boxes

[ayjay]

it flexes enough on the sides that if i were to put a penny on it, the penny would jump up and shatter the glass in my hatch :pface well it's not that bad but i'm sure it would jump a little, don't have any rattles coming from the box itself, just everywhere else in my car so that's good at least... box is weighing in at around 35 pounds right now which is not bad at all for a 5 cu.ft box

[ayjay]

hey i thought you got a new digital camera? those pics are soo small, upload bigger ones so that i can see the box better... looks dope though

[AustinSilvia]

post closeups of the door... gotta see what it looks like

[MECPInstaller]

i'll try to upload afew better pics to my yahoo photo album in acouple days so you can get a better look

[ayjay]

close ups of the door might be tough to do... gotta find the right angles to take pictures that will make them look half decent :pface i'll take a few tomorrow for ya

[Hellion240sx]

yay more pix = more ideas !!!!1

[ayjay]

well if you want some ideas, you can go ahead and make some of these.. my buddy made them for his integra, each door held a Dynaudio 8" driver, and Focal 165k3 (3-way polykevlar) components. the 8's used the airspace from the doors, and the 6.5's ran off of a seperate sealed airspace which ran along the base of the door (about 1.0 cu.ft)... was a cool project

[Hellion240sx]

need more pix of it. o how do you take then tape off of the back of the mold? i started my first attempt last night then i ran out of tape! lol. did he fiberglass his whole door? and how did he make that mold? i have searched so many sites for ideas but none are that great

[MECPInstaller]

Correct me if i'm wrong Ayjay but he didn't make a mold did he? he made a mdf frame and wrapped and glassed it?

[ayjay]

first off, tape on the back of the fiberglassed piece doesn't matter, you can cut off the edges that you don't need... you can try peeling the tape off the fiberglass if you want but it's no big deal cause you'll never see it anyways...

and ya, it's not really a MOLD, it's mdf framework wrapped with super stretchy spandex which was then resined, and then fiberglassed, bondoed, painted, etc...

if you're trying to figure out how to do this hellion, just check the first couple pages of this thread, should be enough pictures & explanations to get you to the point where common sense takes over :pface

[Hellion240sx]

ok ok then ii wont worry about that. check! how did he add on the frame onto the door??? cuz he does have tape on there but what for?also i think thats to much for me... would feel reeeal nice tho

and would it be easier to just fiberglass the whole door?

LOL, common sense, HAH, i hope so :pface

[ayjay]

ya that's a huuuuge project, he was brave to attempt it and it turned out super nice. if you're gonna attempt somethin like that, you pretty much gotta be prepared to sacrifice your doorpanels... the mdf framework was just glued right on to his doorpanel and he cut holes in the panel where necessary to fit speaker magnets... the tape was so that he could keep half his door intact and the bottom half he could work with, he didn't wanna get bondo and fiberglass resin on the rest of the panel, just the lower half:



the hardest part about trying to do this, which is what i found in my car as well, is the seem between the fiberglassed/bondo'd part, and the pre-existing vinyl... i ended up completely re-vinyling my doorpanel after adding a full layer of fiberglass to it to give it some rigidity. i couldn't vinyl around the speaker pods cause the curves were too sharp and i would have needed to stitch the vinyl (and i'm no seamstress :pface) so i was left with some painted areas meeting up with vinyled areas, and those transitions are what are hard to cover up... the only solution i came up with was to use black adhesive backed high performance vinyl, and cut it into strips which i then ran over the edges of vinyl/paint. doesn't look that great and it's the only thing that bugs me about my panels...

my advice is that if you're gonna mod your doorpanels, just mod the area behind the speaker grill so that you can at least cover up whatever stuff you've done with a stock grill... g'luck... my msn is [email protected] , so if you need any more help just gimme a shout

[Hellion240sx]

damn thats incredible! wait dont htey get wet when it rains and he gets in his car?!?!?!?

well anyway what if lets says you spandex the pods right, next you just resin the whole door? then fiberglass it with three or fours layers, sand, bondo, sand, and paint? is that the right order? make it look all one piece?

[AustinSilvia]

i'm not doing any of that sort of custom work, i just wanted to see a picture of it all. i know that's not your car ayjay but i imagine your's is similar.. i have seen sort of far away pics of your doors when you took pics of the sub in the back at the hatch door. i would get into all that but i have brown interior that i really dont feel like messing with cause if i changed something i would want to change all of it cause i dont like the color at all. plus i dont need to do any of that cause i only have one 2 way component for each corner of my car... i'm just doing stuff behind the panel. anyway that is all very nice work. i'm sure i will end up doing something like that one of these days. maybe just for my subs so i can make some trunk room, or just make it look nice at least. by the way how have you found the fiberglass to be working out? is it durable? any problems with cracking at all? anything that is cause for concern? i know like fiberglass body kits are pretty easy to mess up, but since this is all inside the car it's a different story. how thick do you usually make your fiberglass and how much does the stuff weigh? my wooden box with my 2 12's is damn heavy... it has to be at least 75 or maybe even closer to 100 lbs.

[AustinSilvia]

is that a prelude or some sort of honda? those seats look almost like s14 seats, but not quite...

[ayjay]

Hellion, after you spandex the pods, then you resin the spandex, not the whole door... the resin will make the spandex hard and you can then start fiberglassing on top of the spandex... the only reason i fiberglassed my entire door is cause i ripped all the vinyl off and i was gonna cover up the fiberglass with the new vinyl

and austinsilvia, i've had no problems with the fiberglass whatsoever, it's strong as hell, the only problem i've had is the bondo/paint chipping at the top of my door panel where there is a lot of flex when putting the door panel on and also a lot of heat on that area cause it gets exposed to direct sunlight...

oh and you're right, those doorpanels are in a 92 integra

[Simmsled]

I bet that is loud as sin, though i'd think that the imaging suffers a bit. What is powering that setup?

[Hellion240sx]

no im saying, i want to fiberglass my doors and pinat to match the car. how do i go about doing that?

[ayjay]

I bet that is loud as sin, though i'd think that the imaging suffers a bit. What is powering that setup?

ya imaging did kinda suck in his setup too... he had an oldschool sony xm2100g, dual monoblock stereo amp (100x2), sounded pretty sweet... but now he's redoing all of it, he's already custom flush mounted his TN-51 tweets (Utopias) in the A-pillars aimed towards the center of the windshield, and made kicks for the 4's, and he's got a pair of 6.5's midbass polykevlars in each door, so FOUR 6.5's in total... in total off of three xm2100g's, he'll be runnin around 900W RMS, all equalized and time corrected with the Pioneer P9 combo... gonna be TYTE YO

[ayjay]

no im saying, i want to fiberglass my doors and pinat to match the car. how do i go about doing that?

first off why do you want to fiberglass your doors? you installing 3-way components?

well either way, you should rip off all the vinyl off the doorpanels and scrape off the thin foam, that is left on there, with a sharp chisel or putty knife... then you can fiberglass over the entire door with some fiberglass CLOTH (goes on much smoother than the matte) in strips no wider than 4" wide... then you can go head and start bondoing the ENTIRE door, filling in holes/gaps, if you plan on painting the whole thing... sand it down with 80, then 150 and then 600grit, use a primer that has scratch filler, sand that down lightly with the 600 grit, spray 3-4 solid layers of matching paint, and another 4-6 layers of clear coat and you're good to go... when spray painting, do it in your basement or garage where you can get ventilation but also no dust particles...and that's it
