Adz, the shape of a speaker box is important to its sound quality. Would it be possible to use smaller boxes of simple shapes made out of ply or similar, and then house it in a flush-fitting fascia?

I haven't seen speaker boxes made with glass, but thick perspex is common.

THe speaker box needs to be rigid enough avoid resonance, which is why 19mm board is often used, but I guess fibreglass would be strong enough if it was curved or braced. I'm not sure what effect curves would have on the sound quality though. It depends on the size of the speakers you use and what their range is. You are trying to avoid the speaker causing the box's panels from creating harmonics at certain frequencies.

Does this confuse you even more?

whats the point in re-inventing the wheel. There are many kombis around with great sound systems that look good which also hide in various spots, eg under rear seat, above rear door, subs built into backs of frount seats they work great

sorry my bad

If you're using 6x9's they will probably fit in the kick panel beneath the rear seat. You would be able to bolt the box to the back of the kick panel it it was not too large, but you would need to relocate the battery I think. A battery box behind the rear seat would look good though, and be easier to get to for jump starts and maintenance.

If the speakers you're installing aren't subs, you may not need to box them at all, in which case you may be able to leave the battery where it is, but there's not much room in there. Check with the speaker manufacturer.

(Damn typo's!)

I'll U2U a number for some guys that can probably do speaker panels for the type 3 footwell area that will fit 6x9 deep speakers.
they throw the noise in your face not into the seat !

cheers

Try going to http://www.caraudioaustralia.com/  and then clicking on the link up the top to a Downloads section. The first program in there is an Enclosure Calculator which may be of help. Also I mentioned in a different thread that I've asked lots of questions audio related in the Beginner's Forums and recieved detailed replies to all questions asked.

Hope this helps somewhat

Fglass can be used Adz, it will need to be pretty thick though.
3 layers of thick stuff should do it, but think 'thicker is better'.
Its not the best stuff soundwise, wood is always king, but if you are keen, and your after a particular shape - then go for it.

why not make a square box then mold the fibreglass around the wood??? then u get optimum performance of sound and u get ur shape u want!!!!
cause in reality where u mount ur speaker it has to flat!

You guys talk about boxes for the boot...
Have you seen how much room there isnt in a notch?
If you want alot of bass.. you will need to replace the back seat....
From memory, its only about 10 Inches tall behind the back seat...
For 1 12inch sub.. you need a box that will hold 1 cubic foot...
concidering that the engine lid is in the boot you will be taking out the box everytime you want to get to the engine.
I have 2 10inch subs in my fastie... free air type...
Strong backboard behind the seat...
7X10 kenwoods on the back dash...
I get heaps of bass....
Use the boot as your BOX!

yeah thats what i was thinking tazz, and maybe mount a peaice of plywood in the boot behind the speaker. u know what i mean?
:bounce

Not ply......
19mm craftwood.....
mount it behind the seat...
that way you dont have to cut so much out of the bracing.....
cover it in a nice carpet.... and leave the top part of the seat out!
Ta da!
