Fiberglass Sub Enclosure

[Steve@3dai]

I have this "dream system" for my WRX wagon that I'd like to have a reality, but you know how that goes ;)

Anyway, with having a wagon, I bought it so I could slap stuff in the back (camping gear, etc) but having subs in a box would take up that space. Now I've got an idea, but it would need a custom fiberglass enclosure. Is this a good material for enclosures? what kind of resonance, if any would I get with having a sub in fiberglass? Oh, and how sturdy is it?

Getting the rest of my Polk system installed the 8th, EX3 components and coaxes... all driven by a Clarion 4 channel amp. Mmmm... gonna sound good!

Steve,
Fiberglass will work very well as long as it is thick enough.
I would suggest making the walls of the enclosure 1/4 to 3/8 of an inch thick. If built well, I don't think that the enclosure will be too resonant but if you want to dampen the enclosure, look at some of the Dynamat "Extreme". It may be costly, but well worth it.

Thanks,
Kim
