i have 1-10" offset to the left Zenclosure box. I put in a boston G3 sub with a 1000 watt kenwod amp. the problem i am running into is that the sub is moving too much and the sub is not slapping hard. The sub is moving back and forth alot and i was told that the box is too big. What other possible solutions do i have to this problem. Any information will be appreicated.

 

Get a bigger sub
