this really only relates to extreme cars so.....

is it possible to not have enough air space inside a car for it to get loud? most people say just build as small airspace inside as possibe then tune for that size but does it reach a point where theres no longer enough air movement or resonance or whatever else you want to call it for that to happen? and no amount of power will overcome it!, or perhaps even reduce spl

i guess you could say kind of like the theory of a bigger ported box being louder that a small one in a given air space!

anyone?
