Sorry it's the enclosure for the 10" sub

oooo- or are you asking how many layers of fiberglass you need for the enclosure you're building FOR the sub?

LOL!!! and to answer the question and not get off the thread course, generally you want to layer down minimum 3 layers and keep building up until the box no longer flexes. There really isn't a set standard of layers. Curvatures usually require less glass than straight areas. Lets say you have one straight wall, that will be your weak point and require more fiberglass than lets say a 90* angle... I just usually layer more and more glass over until it becomes rigid. And then i test volume and if it's off by too much, i'd make a fiberglass soup sludge and fill as much as possible until it's close.

^^ as i was saying, there isn't really a standard, i prefer heavier mat w/ less layers, Red prefers the thinner stuff with more layers. Either way, it's all personal preference, i haven't had any bad luck w/ less layers/heavier, and i'm sure more layers with lighter sets of Matting would be more structurally sound, but for most boxes i've made, my way still works perfectly fine =P

Thinner material soaks up resin more readily and is easier to lay vertically and upside down than thicker and therefore more resin heavy stuff.

I finished 6 layers of fiberglass mat and it seem strong, I could actually stand on it.

lol, usually i would randomly test by putting pressure with my thumb around the box...but standing on it works too.... lol
