how many layers of fiberglass should i use when a building a box for a 12 at 300watts

depends on the space youre covering and the shape.. a large flat area will be esaier to flex than curved and the larger it is the easier it will be to flex..

so to answer your question, do 4 layers and then check, add more layers if it still seems like it flexes
