jizazz12 Posted June 17, 2010 Report Share Posted June 17, 2010 once you have figured out what subs you plan on using, take the specs of one of the subs and double it. for instance if one sub requires 2 cubic feet you are going to use four, after you have figured that out find a calc or go to psp.com and use theres to figure out how long your ports need to be.don't forget to factor all your displacement into the box size.

rmzsuzuki89 Posted June 17, 2010 Report Share Posted June 17, 2010 Tuning is based on the Dimensions of the port. Go to the12volt.com and use their tuning calculator. Just aim for about 35 hz and youll be fine Correct. Port tuning depends on the port area and length relative to the volume of the box.

tigolbity Posted June 17, 2010 Author Report Share Posted June 17, 2010 i agree it probably would ne easier. but the specs for the sub is 3.4 cu.ft. and 2 4"(diameter)x9"(long) ports. i dont kno how to make a slot port close to the 2- 4"x" ports. im new to this lol. i just dont know Quote Link to comment Share on other sites More sharing options...

Or shorten it for higher and make it longer for lower Quote Link to comment Share on other sites More sharing options...
