i need help cuz ive been told 2 different things by people, one guy said i shouldput polyfill in it, and another said i shouldnt cuz ull heard it flapping when ur playing ur subs...please tell me whats right
just line the box with polyfill if you need it, using the rolled kind, not the loose stuff. staple-gun it to the box. use adhesive if you really want it secure. you won't hear anything.
