The reason to keep the covers on the pillows is the keep the polyfill from getting everywhere, especially around the driver. Because of that I normally just arrange them in there but do not staple or glue them which is normally not needed in a home environment were you hardly move the sub around. You want them in there snug but you don't want to compress them much and leave some space behind the subs vent.
