I am finishing up my fiberglass enclosure but I think that the box in the end will be a little more cubic feet then I wanted due to the space on the sides between the mold and the fleece fabric. Is there anything I can use to make the box seem smaller? My thought as of now is to dynamat the inside and seal off the sides of the box that gives the extra cuft. Will that be ok? Wont affect anything negatively?
