    7 layers is a lot! -- 3 or 4 layers has enough strength to park a car on.
    If at first you don't succeed, so much for skydiving!

    It depends on the fiberglass you use.
    3-4 layers of 6oz FG would be enough for most sub boxes.
    Really high powered systems would suffer under a lot of pressure.

    I'm guessing you're putting 2 8" or 2 10" behind the seats.
    I put 2 10" subs in sealed boxes behind my seats and the amp in the front trunk, but I used MDF for most of it.

    Wow this thread inspired me. I think I'm going to run to the marine shop and hook up a gallon of fiberglass and some mat and go to town

    I don't know if it was overkill or not, but my friend and I used 3/4" of fiberglass on all sides of his enclosure for his 12" phoenix gold titanium...its what the stereo shop told us to do.

    In my opinion, 3/4" thickness of FG is just a little overkill... that box definitely has to be solid though... how big of a box it is, and how much did it weigh when done? Though FG is light (relatively), a 3/4" thick box of FG gets kinda heavy.

    Updated - New Pics !

    Here's a quick update and some new pics...

    So here's a pic of the my car; '81 911 SC



    Here's an updated picture of the sub enclosure. It's working out really well however, I think I'm going to need to re-upholster with some better quality vinyl. The heat and sun is already changing the color.



    Fabrication of the mounting cover for my Lilliput LCD screen. Again made with fiberglass and bondo. The finish is an almost perfect match to the black interior. I used tremclad semi gloss paint and a few layers of clear coat. Worked well.



    Picture of it installed in the car. Basically, I removed the stereo, relocated the lighter, three ways, fogs and attached the lilliput and it's casing bolted from the rear without any modification or damage to the original dash coverings. Hard as hell to get it in but I got it!



    Night time view of it...




    I still have a few things to do to complete but it's almost there. Works great too! I'll keep posting updates.

    Look on the bright side.... if it was hard as hell to get in, it will be harder than hell for someone else to get out. Nice install.

    everything is under the drivers seat. There's not much clearance but I got it in. I'll try and get a pic when the wires are cleaned up.
