Kranny Posted September 6, 2008 Report Share Posted September 6, 2008 multiply the box dimensions for 1 sub by how many subs you will use. example: if you have 1 sub that needs 3cuft to work properly, and you have 4 of them, multiply 3 x 4 to get 12cuft.

Jeremy M Posted September 13, 2008 Report Share Posted September 13, 2008 lol ur gonna want like 2.5 cu ft for each sub with that knid of power...i think for like 3K+ for 1 18 u might use a 4.5cu ft box, so for more power u need a smaller box, but that's JMHO Quote Link to comment Share on other sites More sharing options...
