jeffrm Posted May 17, 2012 Report Share Posted May 17, 2012 i wanna do interchangable ports in my box but i cant get the tuning right for either of the ports. can anybody help with tuning my box with each port i can go a max of 50in wide, 18in tall, and up to 25 deep. needs to be around 8cuft gross volume i need 1 port in mid 40s for spl and one in mid to low 30s for daily. port and subs can be on top or front only because it will be trimmed out wall to wall 03 tahoe z71 4 death penalty 18s 2 ampere audio 3800s @ .5 each 18v 156.7 @ 35hz 158.5 @ 50hz Link to comment Share on other sites More sharing options...
