fibreglass Sub box in process

[DubSteve]

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.

id say make your baffle out of some 16mm MDF just to be on the safe side, 12 mm just seems too thin to me

had alot of experience with this sort of thing and have found that 16mm is the way to go or even thicker (sandwich two sheets together with liquid nails) depending on what sort of power you are dealing with... the thickness in the fibreglass section you have made is not as critical however as its curves lead to a majority of its strength...

your fibreglass section looks fine, although its a little thin in some places, however again it depends on what sort of power you are going to be running...

keep it up, will look great when its finished
