I'm putting a Rockford Fosgate P3 15 in my 2003 Silverado, just one. I'm removing the center console for more space, and I'm looking for recommendations for the box, I can build to any specs needed. I am pretty sure the sub needs 2.25cu ft of air to perform well. I can make my box as tall as I need to, and it can be 10 depth. Ported, sealed? Any help please?
