I am a little stumped on this one: my current box design (1 12") is louder with the car sealed, than with the door open. typically it is the other way around. I am not as well versed in the Car Audio Industry, and over the years of competing, I haven't really ever seen this happen.
Does anyone have any insight as to why this is, or is this more common than I know.
Questions, comments, insights are welcome.
