Yeah I think I will move the bottom sub closer and just do two ports on top and see how much area I have if not I will go with 15" and do one big port behind the driver
Ok I know this is a dumb question but what is the math to figure out how much port area I have base times higth? Or do I include the lenght to. How much port area should ihave for three 18" level 4xls in around 16ft^3
Thanks for all your help
yeah i was trying to stack them but dont think i will have enough room only 35" tall after the mdf about 2" worth thats what i was thinking it would not be enough what about adding two more ports on the top one on each side of sub
