[QUOTE="havoc06, post: 347662, member: 548712"] ok this is what you do. Find the displacement of the sub. This is how much air space the sub takes up. Add that to 1.5, and you should see how big to build your box. If you dont want to do that, somewhere around 2 cubes before port and sub displacemt should be ok. To find out what a 4 inch port comes to in sq inches, you do Pi*Radius Squared which is about 12.5 sq inches. You can build the square port that is 12.5 sq inches to be the same as a 4 inch opening. Personally i would do a bigger port, something around 30 sq inches to make it sound better. [/QUOTE]
