nice idea, i might try that in some of the straighter parts because i understand that fiberglass is weaker where it's straight right?

i can't remember the glue i used to stick the cloth to the fiberglass (i'm at work right now ) but it can be used to stick anything (so it says) lol. when i get home i'll try to post it

 

it must be something like ca glue then...

 

Ideally fiberglass that is 1/2 in thick is highly desirable for hard hitting bass. Even thicker will even be better.
You can also add in some type of dampening material and fiberglass over that as well. Let stuff cure in between. You might double check that your enclosures still fit where they're suppose to and hasn't changed shape on you (shrunk or distorted). That first part looks like you didn't get enough resin on it and you have lots of air in the mat. Good start and you have to learn from beginning somehow. Keep at it. Using thicker mat (3-6 oz?) will build up strength and thickness the fastest. Cut the stuff in strips in various lengths and widths and have piles of it ready to go.

 

the one man you can trust on car audio... I've seen the difference in mats, unfortunately, the fiberglass wholesale place only has 1oz here in l.a. They'll have 2oz in like two weeks. You have more pics of the minivan? I saw one today slammed to the ground, looked awesome.

 

thanks for your reply man, btw ur car looks wicked!! i noticed i have a lot of air in the mat - would that be a problem? noticed i didn't have enough resin after the early stages and tried to add some more to it later on. i thought it helped because when it dried again, it hardened up pretty well so when i flick it with the nail of my finger it sounds like hitting hard plastic or something. what kind of dampening material would you recommend using?

 

here's the latest update pics


these are dry after 6 layers of fiberglass. i'll be adding more soon, though they seem really solid already! no signs of moving at all when i put my whole 92kg self on them but i think just to be safe, i will add more layers. after that, i'm going to smooth everything down, re-cut the holes for the subs to go into and start preparing for whatever finish i will use.

does anyone have any ideas what they think i should use to finish them? i really want to get them painted, but i can't seem to find body filler anywhere (the whole being in Thailand thing), though i'm thinking about going to a car repair garage to ask if they have it - does that seem like a good place to try and find it? it probably sounds like a really stupid question but i really have no idea

 

A bit late with the updates but things have been a bit busy lately

All fiberglass has dried and been sanded down with grade 60 paper, then i applied one layer of primer paint (not entirely sure why), though it did make it easier to see any bumps in the fiberglass, and also to prime the MDF for painting later on.

In the pic below, one enclosure has been painted and the other covered with car body putty (the kind they use here to repair car body work).


After these pics were taken i've applied putty to the other enclosure, filled up a bit of space on the inside of the enclosure where the MDF rings meet the fiberglass using the putty, and added 4 more layers of fiberglass on the inside (just to be safe )

 

Wow, that is a LOT of fiberglass! But better safe than sorry! So you found body filler? Thats good. I can't think of anything else that would do the job, especially if you plan on painting. I'll most likely be putting carpet on my boxes. Head unit and amps should go in tomorrow! Then I get to go buy everything for glassing!

 

The thicker your enclosure walls, the more dense sounding your enclosure will be. It ends up making harder hitting, quicker sounding bass. I've used aluminum faced or regular dampening (black) Dynamat type product in my enclosure. Then fiberglass more over it. At this point, you can just add some dampening to the inside walls; a few strips here and there and leave it at that. Don't worry about adding fiberglass. Add some polyfill (White fiberfill like what's in your pillows at home) to absorb some of the back waves of the sub so it doesn't fire right back onto the backside of the sub. Your subs will sound great.

Onestop, I'm emailing you Ody pics.

 

wow supa, they came out nice... I'm going to finish fiberglassing mine today and adding some bracing. I'll send you some pics tonight hopefully.

 

ok, latest updates.. i've painted them flat black after sanding them down (really tiring!!)


then i went over them again with putty where it was needed (quite a lot actually )


i sprayed them flat black again after sanding them down and then went over them AGAIN with putty where it was needed


then after sanding down with finer wet & dry paper, i applied a couple of layers of metallic black


there's still quite a lot that needs done, but it's taking quite a long time, i might have to forget about "perfecting" the finish and go with something that looks decent i don't have much time to add any more pics or info, gotta go!! more coming soon...

 

Looks great!! I see your Peter'ing around.
(Mr. Peter body filler).

 

These look good, i wanna see them in the car and how heavy are they with the sub installed?

 

haha, yeah what a brand name, eh? stuff works pretty good tho i haven't had a chance to install them fully, i just wanted to hook them up and test them out, and so far so good! they prob weigh between 5-10kg if i remember correctly, things have been so busy lately i haven't had much time to do anything properly anyway here goes...

i drilled a slot on the back of both of the enclosures to fit the low profile monster cable i have for the speakers, then i slid them in and sealed them with the putty, sanded them when dry and spray painted them to match the appearance. here's roughly how it'll look when it's done (of course all the wiring should be neater ).


here's a close-up of one of the subs. there's a bit of touching up needed, but i'm pretty happy with them damn, my car's dirty though!!


the next pics i post SHOULD be of the finished product hopefully that will be tomorrow

 

They look great! I'm personally going to be carpeting my boxes, if I ever get to do them. I really like the positioning and aiming of the subs. It looks like they will hardly even interfere with the cargo room in the back. Good job!

 

Yeah I really like the position of the subs as well. Id like to give it a go on my 09 when I get time.

 

Supa, get some grilles so you don't have to be ssssooooo careful.

 

thanks for the feedback guys i was thinking about getting some grills too, because when i used my old box, things would ALWAYS find a way of coming close or touching the speakers.. the only thing is i can't seem to find any over here i've seen some really cheap looking plastic grills in a few markets, but nothing decent looking. i was also considering making my own out of a few bars of some kind of metal, like maybe 2 bars running vertically either side of the MTX logo, and protuding enough so that it would still protect the sub..

 

Very nice work supafly. Im starting to plan out my Audio project as well.

 

I did a fiberglass encloser TOO!!
