I am about to finish purchasing all of my equipment for my new build. 8 15" comp D sub's 4 kicker sx1250.1. I am taking the third row out and beginning my build from the second row back. My question is what would be the best way to implement the sub's. Clam shell, 4th order, 1 big port. Also I need good design ideas. Money is not really a problem I just don't really know where to start.
