enclosure theory/question

just a quick question, me and some mates built a subwoofer enclosure for 2 15" subwoofers..unfortunately i dont think the box is going to be strong enough, however i was plannong on fibreglassing and making a whole boot out of the box kinda thing..if i fibreglass over the box and make it airtight and cover the box with fibreglass and give it some extra layers will this help increase the bass response, in the event that the box starts flexing(if it didnt have fibreglass at all covering it)

If you cover a weak box with layers of fiberglass it will decrease any flexing of the box and increase the bass response.dream it, build it, fiberglass it

thanks..thought this would be the case :)

thanks..thought this would be the case

but fiberglass is weakest when it is in large flat sections. that is a good excuse to thro some curves in it.

yeah i was thinkin of doing something fancy ;)
