in the near future (next couple of months) i plan on getting a 15 inch brahma, i plan on building a box, i want to port it and i will be running about 1100 to 1200 watts to it. i want to know what size the box should be to optimize the sound for this bad boy. also i want to know what all you brahma owners have your box tuned to and how it sounds. i would like a great deal spl but still want to retain sq.
