I built a simple square box that's too large. The ideal size was 1500 cubic inches and mine came out to be about 2500 cubic inches sealed subwoofer -- posted image. The problem is that it bottoms out. I was told that the large box doesn't give the cone enough back pressure.

Would adding more fiberglass fill help OR do I need to un-install and re-cut the box?

Thanks

Just add material in the box until you get to the desired airspace you want.

No. Adding fiber-fill to an enclosure will make it act as if it is larger, not smaller. You need to either re-make the enclosure, or add solid material to the inside like 2X4's glued in place, or add extra bracing.
