03silvergt Posted December 9, 2009 Author Report Share Posted December 9, 2009 Will that size port work for my box? Do I need to re-evaluate my box dimensions and go with something smaller? I am lost with this stuf. You know, that Best Buy box is looking better and better everyday, lol.

03silvergt Posted December 9, 2009 Author Report Share Posted December 9, 2009 gross is how big the box acually is. net is useable airspace So the formula will be: gross space - port space= usuable space?

Cr@sh Posted December 9, 2009 Report Share Posted December 9, 2009 You can use the industry standard of 15-17 cubic inches of port per cubic ft of box or this works well to: http://www.carstereo.com/help/Articles.cfm?id=31 I came up with 4cubic ft net enclosure tuned to 33hz with the port being 12" height/3"wide/15.75"long Quote My old install at cardomain, never finished!
