after this semester of college was finished i was thinking about making some fiberglass boxes for my trunk to be as efficent as i can with my trunk airspace.

anyways i was wondering if fiberglass boxes do " Sealed box" very well. i'v heard its good to use some liquid deadining in any fiberglass box....

i plan on putting them in the wells of my trunk but i know the hing rails are going to get in the way.....shouldi try and make like a groove for them...is it a very bad spot any ideas on how to combat that problem would help^.^

Fiberglass will seal perfectly fine. As for the hinge rails, maby unbolt them and use the hols to mount the box...
But im not exactly sure what your talking about so maby that wont work.

what on earth is a hing rail?

I would suppose a hinge rail is what the lid swings on...

But to the OP, there are plenty of companies that make the very box you are considering... Audio Integrations is the first that comes to mind... Might be worth a look for inspiration..

As the others have said, glass seals fine, they wouldn't make boats out of it if it didn't..

If the fiberglassing techniques are done properly especially at any seams or abrupt changes or weird angles....it will be sealed just fine.

I always run some silicone at junction points where there could be a leak.

But if it's designed well enough you shouldn't get any weird junction points or sharp corners that are impossible to get a caulk gun into.

Yes....I've done this.

now that im able to reply -.-.......i under stand that they seal i just ment are they good for sealed boxes for subs or is ported a better way to go with glass....

and is deadining a must when it comes to glass? if so whats the best thing to use?

"if" i get them i will be building them for L7 12" solobarics...one on each side of my trunk sort of like the audio integration one...and i must say thank you very very very......very much for showing me that sub box it did inspire me ^.^ in fact it will prolly work better than the previous design floating in my head

i have seen both sealed and ported. i am not high enough in the box building to build a fiberglass ported box well. i did one once but it was with Barry Redman who is like many of the people here like Glassman. point is it is a exacting art doing a ported glass box.
hopefully genxx won't crap on that statement
