fibreglass Sub box in process

[Soundofav6]

After a 12 hrs on the job and countless amount of surgical gloves, the job is almost done, just gathering patiences of making a templet for the MDF and also pondering how I should stablise the MDF on fibreglass.

Hopefully it would sound as nice as any sub box

Thanks for the demal Rayray. Such a usefull tool to have.

Nice work there Louis and I quite like where your going with that I may even stea lyour idea off you mate for my car whenever I ever decide to put my sub in the car

nice one! mdf is porous so just glass the two materials together. how are you going to attach the box to the car? [ie. so it doesn't move around.]

I had to do the exact same thing i a barina foir Clarion. To put the Face on the glass, i just glassed it on.

Only after a loyalty fee mate....lol no such thing as stealing! I got the idea from some one else too.. we can DIY together.. not hard but just messy stuff.

I am pondering if I should get the MDF, cut in shape first than glassing it inward from the subwoofer or outwards.

Also cutting a 10" hole with jigsaw.. any tip? Should I start cutting from center--> radius --> and cutting the circle ?

Attaching the box to the car is another challenge, I have a few ideas, too hard to put in words atm. I am sure I can figure soemthing out, "go with the flow" ( THE SPIRIT OF DIY)

It looks good mate, and it should be heaps lighter than an MDF box. Nice job!

When cutting the hole for a 10" sub, DO NOT CUT A 10" HOLE! Your sub will fall through! My expeariance says cut a 9" diameter hole, but check first! Your sub should have a template in the box, if you have that. When cutting the hole, use a jig saw, and just go slowly. Drill a hole first near the edge, and just work your way around the circle you have drawn.
Again, just take your time.

With the FG, make sure it's not too thin that it will flex with the bass. Else you will get realy bad losses in sound quality and also in db.

How thick should the fibreglass and MDF be? I'm thinking of doing this myself one day too, this being inspiration

last time i did a fibreglass box it ended up being ~4-5 layers of matting thick with a 12mm sheet of mdf.

as for attaching it, use lots of velcro.
