Advice Needed For Boot Mould For Sub

[NISZILA]

Hey guys

Just needed some advice...

I want to rebuild my boot so that my sub (12") fits into the right hand side of the boot. I want it moulded in so that it can be as out of the way as possible so I can utilise the rest of my boot space. Atm my boot is half filled with a sub box.

What I was wondering is, if I do the moulding with fibre glass, what is the likelihood of it cracking. I want to build an MDF frame and make the fibre glass mouldings around it, but I'm worried about cracking the same way fibre glass bodly kits crack over time. Is there a better way of doing it or should I not worry about this. I figured that with the extra rigidity of a good frame, this may not even be a problem.

Any advice or previous experience would be greatly appreciated

Build it thick and it will be fine... Build it thin and it will crack and explode under presure...

You have little or nothing to worry about mate ... a fibreglass box will be fine! im making one for my tyre well now .. just for tips make sure you get all the air bubbles out first because they are a killer

Cool, thanks for the advice

Might start some measuring up and designing this weekend

oh one more thing .. Get like 250g or whatever measurement they use for fibreglass because i got 400-450 its way to thick even tho you can split it its just useless

For a single 12" subwoofer you'll want the wall thickness to be between 6mm and 12mm depending on how many bends, strengthening ridges etc are in it.

When constructing fibreglass enclosures here we utilise an extremely sophisticated testing procedure to see if the enclosure is strong enough. I put them on the ground and jump on them. If the wall flexes at all then it is not strong enough.

humm thats some good testing you got there haha

I think I need a few more layers on mine yet .. I got 3 layers of 450 and it still flexes.. Not to mention leaks on the bends. :S

hey mate

here is a pic of my 10inch in the boot. to fit in a 12 is no probs just need to extend the front of the box forward another 3-4inches. (did that in a mates car) maes the edge of the box come in line with the boot itself.

might make you change your mind in fibreglassing a sub box.

That's an awesome job!

Now you've got me rethinking my design

Might take me a couple of weekends to put it all together. I'll post up some pics when I'm done
