how thick to make the fiberglass sub box?

[gritt]

gonna try to make an enclosure for 2 8" sony explods i have laying around. maybe for one 10". dunno. (don`t laugh, i had the 8"s custom fit in some cheap ass wal-mart tubes and they sounded great in my taco). anyways, i have a compartment area in the back of my 84 z. i want to use the fiberboard that makes up the compartment and add fiberglass to thicken it up, to keep it from flexing. how thick whould i need to go with it if it was just fiberglass? (the top part may all be fiberglass so i can make the custom speaker mounts.) and suggestions or websites?

just keep adding layers until it doesnt rattle.

there is no uniform thickness..its all about the shape and type etc. Just go till it dont flex

i have seen in audio mags where they use some thick stuff...polyester cloth or matte, something like that. know what i`m talking about? or should i stick with the fiberglass...

it doesnt really matter.. if it doesnt flex it doesnt flex. thats all

quoted for truth.

I have this stuff, called fiberglass filler. its like 1/16th thick or something, and you use it in a big flat spot, and glass around it. it takes the place of about 4 layers. But in the time it takes to work one thick as piece thru, which has to be saturated, you could have just as easily taken 5 or 6 large squares of regular glass and put them in the same spot.

It will all have to get to the same end result, a rigid box.

Fleece blanket works well too. For Sony Xplod 8's I wouldn't think you'd need more than a couple layers.
