I have a pair of Kicker CVR 12 inch subwoofers in a sealed enclosure?

the owners manual says that all sealed-enclosure airspace should be filled to 50% of poly-fill. It also says that not to make the airspace greater than the SQ, maxium enclosure volume. I know what poly-fill but what does the rest mean? Do I put in a 1/2 pound or 1 pound of poly-fill in for each chamber?

The sealed compact (minimum enclosure volume) is 1ft3 (28.3L)
Sealed SQ (Maxium Enclosure Volume) is 4.6ft3 (130L)

Thank you

poly-fill is only if you have a small enclosure to trick it and make it seem bigger than it is. it does not need poly-fill unless your min in space for a really small box. and just dont make each chamber more than 4.6cuft of airspace or you could blow your subwoofer. which i dought your gonna put each 12in subwoofer in a 4.6cuft box thats really big. put those 12's in a 2.0cuft total 4.0cuft.ps the bigger the box the lesser rms wattage it can take. but that wouldnt really change unless you put it in a 3.0 perchamber box probably drop to 300rms each subwoofer but a 2.0 should be fine at the same rms power kickers are under rated anyways they can take about 200 more rms than what they say and be fine. and you do not need poly-fill unless like i said your gonna have a sealed enclosure less than 1.0cuft.
