Help with port design.
Ok, tore everything out of the car last weekend and am downsizing a bit. Before I was running 4 15" Kicker L7's. As per the kicker reps recommendation I put them in individually sealed boxes, It sounded ok, but was never as loud as it should have been. So I am now redoing the system and only using two of the subs. The interior box demensions for each sub is 15.5" tall x 17.5" deep x 27.25" wide. I want to port the box this time but have never built a ported box and am reading conflicting reports on the size of ports needed. As best I can tell this sub has an xmax of 15 mm and I am trying to tune around 33 hz for a nice blend of musical quality and spl. I will be pushing them with an atomic 3000.1 at one ohm. Please help me with the port size and design.
