Advice on DIY stealth sub box

[shail 0]

Ive decided to TRY and make my own stealth type sub enclosure. I say TRY as ive never used fibreglass before, so it'll be a bit of a learning curve. If i mess it up it'll be a call to autoacoustics to get one ready made - but you dont know till you've tried right?

Any tips on using fibreglass? ?!

Not sure when i'll get the time, but once its done, and only if im not too embarassed with it, i'll post a 'how to' type thing up here.

get loads of pic's and dimensions of someone on here who already has one and figure out the best way to start. Not much help but hope it may help a lil

Cheers for the ebaylink. I've seen that, but it says it s for a 5 door only. Ive got a 3 door. I never knew there was a difference but looking at the autoacoustics website they list the 3 and 5 door seperatly.

ok, working with fibreglass. make sure you wear gloves, lol. gets everywhere, and id try covering the inside of the space you are planning on making the box fit into, use some plastic sheet (visqeen or something) or a thick binbag and spray loads of expanding foam into it to take the shape. then once dry and solid, remove the sheet and you will have your basic shape. now sand/carve the shape about 10-15mm smaller on the foam, then you can shape the fibreglass around that. once you have a few layers on there, make a small box shape to suit the fibreglass, (with a 10"/12" hole with mdf ring for your sub.) and basically cover the box, and bond the shape on. then keep going over the thing with resin. that was a really crap writeup but should give you an idea. thats just how id go about it, but i normally bodge stuff. lol. good luck.

i find, when forming glass to a particular shape, to line what ever you are doing with loads of masking tape first. its really cheap to buy and peels off easily after. then a thin layer of vaseline so you can remove the glass from the panel after easier. start with glass matting in the thinner type and after 2 or 3 layers, switch to the thicker matting. make sure the glass goes off before removing it. best to do one panel at a time leaving the set ones in situ so it all bonds together, otherwise you will get in an awful mess. once you have the basic 3 sided shape set off(back,strut and boot sides) you can remove the box and add more layers of matting or use normal glass fibre out of a tin for more strenght and thickness. i always try to sandwhich a thin piece of mdf for density in the larger flat surfaces,adds strength too. an 18mm mdf front needs to be added and glassed in to mount the sub of your choice, and cut the hole for it prior to fitting as its much easier and you can still work on the inside too. dont forget to add some acoustic wadding to the inside when done to increase the acoustic volume of the box and therefore fooling the sub that its in a bigger enclosure than it actually is! good luck, a little patience is all thats needed and some spare time to complete!
