This thing is giant. I plan to install this in my G21, does anyone know how much space is behind the factory Polk sub? Will I need to do some serious cutting beyond just the 10 to 12 inch opening? I figure that I may also need to add some support since this thing weighs like 35 lbs and may need some reinforcement.
