Integra Fiberglass Enclosure Version 2.0

thanks guys for the comments...

first to clear it up: its a 15 inch sub (Ascendant Audio Atlas 15")  not an 18"...when I said 18" ring i meant the outer diameter of the ring was 18", which is what was tough to fit in the cargo cover since there is a very limited dimension between the back seat and the hatch glass...an 18" sub would definitely not fit in an integra in the method I used...

As far as layer of glass blufab - to the contrary, i used very few.  As explained in the first post I believe - the glass portion (top part) has no sound pressure on it.  If you look carefully all of the sound pressure is exerted only on the tunnel and the 3/4" MDF box below.  The tunnel is the only glass with sound pressure on it, and since the tunel is only a few inches high, it only required a thick layer of resin on the fleece and then 2-3 layers of glass around it...hard as a rock even with only 3 layer tho.  I think i only used like 2-3 layers on the whole top as well...

As for how it is mounted - like i said the dimensions are very tight, and I have had to modify the plastic hatch liner pieces to accept the new large speaker ring as the hatch closes.  It sits in the regular hinges for the cargo cover, but all that weight cannot be supported by those plastic panels (i tried, and it sqeeks like a mother F'er, and sags the panels)...so I created a false floor of MDF for the hatch, and made an adjustable support for the box from underneath using 3/8" threaded steel rods bolted to the false floor.  Four rods bolted in vertically are adjustable to just reach the bottom of the box (about 2 inches above the floor) and transfer the weight to the car chassis.

Thanks for the comments again guys :)
