This is a pick from a helluva fberglass man. Proving the strength of kyntex mat. Just 3 layers and a couple of stiffening ribs. 1/8" thick.

why would anybody doubt fiberglass in the first place
if it was a weak piece of **** why would chevy have used it to build the body of the corvette for 20+ f uckin years

Meh, there are people out there that doubt it...I think they think it will flex if you used it as an enclosure.

i mean they use fiberglass for a bunch of custom stuff, n they most of the times very strong. i guess he doubts it if u only put a very thin layer with no like strength reinforcement, but dunno, not that knowledgeable in fiberglass, altho i'll start practicin soon as i would like to custom most of my car soon

Fiberglass is the way to go if you want that custom look;)

Plus, its e-a-s-y, and fairly cheap, to do:)

I think the bigest issue is that a lot of people are confused about what fiberglass is and/or all the different types of glass that can be used..

I was told (errantly and it sounded wrong to me) that the 'chopped matt' would be stronger than using 'cloths' and that I would (should) need about 1/4" + thickness or more (10+ layers of chopped matt) to be able to reasonably house some subs.. But, as I talked to more and more people (and did more research) and contacted those in the fiberglass industry, I learned that I would probably be able to get away with 4 layers of "bi-biased" (bi-directional strength) cloth (which uses 1/2 the resin as chopped matt, by the way) instead of 12+ layers of matt.. That means the thickness would be under 1/8" and the cost about 1/4 of matting it up (and weight would be MUCH less)..

What I think I'll end up doing is, 3 layers of cloth (like the Knytex shown here) with a little carbon fiber roving (thin thread like strands wrapped/twisted into a ropeish thing) mixed in for added strength.. Given the shape of what I'll end up making (and the outer contours), that should be fine..

As a point of reference.. There are 'space' and flight/boat applications that use fiberglass as support structures that are 1/4" thick cloth buildups in some cases... If you can trust your life to 1/4" buildup of good cloth, how can you expect that sub-woofers wouldn't work in something less?
