some forwardfiring/sealed off questions

well i got my avalanche 15 pointed towards the cab and sealed off but i got a few concerns.

does it has to be completely sealed off like the way if a box has a tiny leak it will screw everything up. i can only get it sealed up like 95%-98% or so since the hinges for my trunk go through the rear deck so i have to leave room for their range of motion. i did try to get it best as i could.

does fiberglass resin eat expanding foam, i want to cover up the expanding foam in fiberglass resin to make it harder since it seems a bit squishy kind of firm but not exactly rock hard as i would like.

To make sure everything is sealed up i can sit and listen and see if it gets louder when you open the trunk up right and if it does that means i got somemore sealing to.

You need it airtight...completely.

what enclosure do you have? sealed or ported?

as far as sealing, i think you need to go airtight.

and that last idea you had is pretty good, about opening your trunk //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

like i said that might be a problem due to the trunk hinge not unless i fab up some kind of boot(like a shift knob boot) or something. and does anyone know about the resin eating expanding foam? the enclosure is 3.0@30hz w/45sq in port, much better top-end than my idmax setup without even tuning it.
