Possible to Fiberglass a Premier 5000SPL?

What the heck got your panties in a bunch! , don't bring your problems here.  This guy came here asking for advice and here your picking a fight.  Do us a favour and chill.

Until you your ready to co-operate i think you should be suspended and make a manditory donation to this site to re-gain access.

The box IS 1.5" thick.  The part you see as 3/4" is merely the vent face, where it was not necessary to double stack the HDF.  The exterior of the box was built around a "sealed" enclosure, extending the box length wise to make room for an "external" port.  I am not the one who designed nor built the box. To be honest I dont' know the reasons why the shop that built this did it the way they did. But being in the military, especially in Korea, doesn't leave me much time to plan these things out, now does it?  Here's a quick diagram that might help you see the construction. Then again, it might just confuse you even more...

Where did I say I used the gain as a volume control??  I suppose I reach into the trunk and use my pocket-driver to adjust the gain between 0 and 1/4 gain when ever i want to turn my system up and down? I set the gain at 1/4 in order to hold the amp back from it's full potential and to minimize distortion.  I have a nice head unit for a reason.  THAT's my volume control. 

This "sh*tty set up" is the reason I'm starting this project Captain Obvious.  Sponsors don't just decide to give someone gobs of cash to deck out their ride.  I have two sponsors currently, both of which are classified as "quasi-sponsorships."  In case you don't know how this works (it's clear that you don't), a group/company might find something that interests them about a vehicle.  In my case, the interior of my car was what drew these guys to me.  Back to the point, a quasi-sponsorship allows the sponsor and sponsoree the opportunity to work together and learn what the other expects with minimal contracts involved before signing to a Full-Sponsorship.  The project I am working on here is my way to show the sponsors my ideas, designs, my attitude in working with them, and my skill and knowledge on this subject.  Currently the only thing that I lack is the F/G skills to accomplish this project with the woofer I have, hense this reason for this post.  By the way, how you said that would imply that I am demoing Pioneer's products...  Do you think I'd be here asking for YOUR help if that was the case? I think not. 

Well, I'm sorry you feel that way.  But I am glad I could help you feel better about yourself.
