[QUOTE="evo2k3, post: 167651, member: 546246"] ok, lets get a start on this.....the hieght and width of your port are fine, you should not have problems with noise. I would first suggest that if you have the room to go bigger, something 2+ cubes after all displaments. which brings me to my next questin, was is the exacst displacemt of the sub? (your owners manual with explicitly list this). What are the biggest demension you are able and willing to make the box? If you wanted to stick with those demensions (which you absolutley can), I used .1(a decent guess) as the speaker displacment leaving the net volume to be 1.421ft^3 ...useing that and the 12.5*1.75" port, its length should be 17.17 inches to tune it to 39hz ...i would still like to use the exact number if you can get them, but the guess will get you very close to 39hz.
