dwright27 Posted May 23, 2011 Report Share Posted May 23, 2011 Why such a small pass band? Generally of you shrink the port area, you can narrow your pass band down ( maybe it's increase the port area??

dwright27 Posted May 23, 2011 Report Share Posted May 23, 2011 Stupid phone posted before I was finished ^^ I'd do around 4 - 6 cubes sealed ( I wouldnt go any bigger then 5 depending on power ), and I'm curious where the box will be and what kind of vehicle?
