How are you fastening this down dude? Out of curiousity..

update:

done some fiberglassing,

did 4 layers of jsut resin, now done one coat of aircraft grade resin and matting, its pretty strong already but going to do another layer or so

It's better to just apply resin to the material to make it stiff, then apply extra fibreglass matting to the inside of the construction, for strength. That way the outside can be made smoother far more easily.

tom - two hefty bolts throu the bottom throu the rear bench

Geehawk - yes on some encolusers but if you look at the earlyer pics you can see that i have a base, therefore no way of working on the inside.

So your not planning on cutting out holes to fit the speakers then

With correct amounts of resin already applied, there should be no reason not to cut out the holes and gain access through those. They're big enough to get a small child through

nice work there, just outta interest, why not create an amp rack outta fibreglass to fit on the rear seat back????would finish it of nicely

also with the resin part, if you put the matting on the inside, you make up what we here in SA call "milkshake mix" - basically, its fibreglass resin mixed with bodyfiller and hardner - makes a milkshake like mix(duh) that when applied goes on very smooth, and hardens nicely!!it is also a lot easier to sand smooth!!!!

but still great work!!!

oh the milkshake mix goes on the outside obviously

trust me im the one with the enclosure sat in my garage there isnt enough access to do it properly, i would rather do it properly and spend more time sanding than trying to do short cuts and not have a as strong finish.

One thing I will say about this......








have you made sure the volume's correct for the subs?

[insamoufonyx]

yup, already calculated the volumes

[Collin]

yup, already calculated the volumes

I'm intrigued - how do you measure the volume for an install like this before building it?

[insamoufonyx]

i work on aircraft engines and use a CAD program, so i deisgned the frame on that, then coverd it using curved surfaces also on the cad package then it calcultated the colume for me

[Collin]

Nice one.

Show off!

So what's the cu ft for the install then? They're 12s right?

[insamoufonyx]

havent got that info on me as i did it when i was at work, will look tommorrow if i rember

and yes its for two 12" JBL subs

[insamoufonyx]

its taken agesss to dry, its now set enough for me to cut the holes out



and test fit



and then test play, it was rediculasly bassy even with gain on 1/4 on my amp lol, going to be great when done!

[Collin]

Niiiiice!

Can't be bothered to run back through the thread, what amp are you using?

[Ro8bieg]

look on the 1st post of this thread and it says there
