My first comment to you would be to increase the port area by a VAST margin.

Four 4" ports is not NEARLY enough port area for 4 15" Strokers. Hell, I would use 3-4 4" ports for ONE 15" stroker.

It will definitely increase the output (SPL), and if done properly it can retain any sound quality.

will it be a drastic difference in the output? how do i go about and figure out how much port area to use?
