fibreglass Sub box in process

[Mrk_Mickey]

The sub box i'm going to be building soon is going to be similar to yours, and the materials are all supplied by my cousin. i think he bought fiberglass cheaper than that, i'll get back to you

The finished product looks fantastic! I would have done a few things differantly, such as making a pannel so that it hides the tail light cover, but thats just me. Good work all over!.

Excellent jobbie!! and more imprtantly, howz it sound? and a quick question, how do you secure the fiberglass to mdf without gaps?

howz it sound? and a quick question, how do you secure the fiberglass to mdf without gaps?

the sound is excellent! I had to cranked up the amp and bit more, I could have use more resin, it makes a fizzy noise at low volume. I suspect it is the undesolved fibre glass. With an overkill of MDF total 2 layers and spacer holding the subbie with glue and screws, surely thats not to blame.

As to MDF to fibre glass. Took me a while to figure as I had about ~1cm of gap to fill. I tried 2 techniques. ..diagram is easier.
Basically filled the gap and glasses it on. But first technique worked just fine ie, sliping the "half palm sized" resin soaked fibre glass between the gap before folding it on the dried fibre glass seems to work better on some areas vice versa.. than glass one overlaping 4-5 layers on.


Note the use of resin soaked fibre glass.. it is rich a green comparatively to pale green/ yellow.. Rememeber Go crazy soaking the fibre glass !!!!! Don't go cheap on resin, turns out stronger as too !!

I had thoughts about doing panel hiding the light, but it worked out to be like an extra feature.

YEah please let me know... coz I plan to do the other side before for the amp before uni starts.

I still have to meet up with you to see how your shifter's going, so i'll come check out your sub box and hopefully by then i'll have some details dude

The fibre glass I had, looks differernt to ones sold at bunnings. Bunning's fibre glass looks thicker and interwoven into a sheet whereas mine looks thin with fibres in random direction and press into sheet.

So next project, where should I get fibre glass from? Surely I can get fibreglass for cheaper than $25 per square meter. Knowing my father, he would not have $300 worth of material lying around.

the woven stuff you speak of is called woven matting (finnily enough) and the more random stuff is called choppd strand...

it is said that woven gives slightly better strength and is therefore better if you need maximum strength with mimimal material

i prefer chopped strand as you can get it thicker (ie. less layers) and i find it easier to work with, each to their own though....

$25m2? jesus thats an absolute ripoff, from a fibreglass wholsaler i remember getting mine for a few dollars per lineal metre, with the roll just being bigger than 1m wide..

back when i bought a whole heap ofthe stuff i was also able to buy 500ml of catalyst for about $10 and a 20kg bucket of resin for around the $130 mark (looks like one of those massive bulk paint tins)

its not too much per kg/litre to buy it in smaller portions either...

its all a learning experience though, i mean hell i made the exact mistake when i started playing around with this stuff, felt like kicking myself! haha

great job once again

Thanks for the long input mate, you are a great help.

Chopped strand they are called.. cool, now I know. Now days everything is so expensive, inflation I suppose. And again, I may have gone to wrong places to get my materials, now I know next project, I would try other places, as others metioned boat places for fibre glass.

It is all a fun and a learning experience.

yeah mate, well when I get my car back, we will go out for a drink or soemthing.

wanna do a fibreglass job for me?? il pay ya

want a AVCR fiberglassed in the aircon vents.

[DubSteve]

Nice work Louis I will be visiting you in the next few weeks to see a few things that you have done and also see how the project is going, I would like to incorporate the fibreglassing with the relocation of the battery together, I think it would work nicely

Doesn't sound too hard, we will meet up one day and see how I can help.

I reckon it would work nicely too steve.

no worries mate

have a look on the net for some car audio forums such as www.mobileelectronics.com.au which if full of information and people who are more than happy to help, may also be better than here as there are more people on there doing the same thing and will be able to reply much sooner or give you more definitive advice...
