So to start out this box will be going into the trunk of a 2005 chrysler 300c. Sub is a Skar Audio DDX 15 being powered by a matching rp 800.1 and max dimensions are: 17H x 31W x XD (D = anything really to make 4 cubes and fit aero port inside box if Possible). I already have a 4 cu ft slot ported box in the back with sub and port facing into the cabin, and it hits nice but i like the look of aero ports plus a change is nice every now and then.
Now my question's really come down to: Sub/port placement ( IE: sub up port back, sub/port forward, sub back port forward) and what size aero port(s) should i go with? Looking for around the 32Hz range.. Also is there any advantage in having the length of the port inside the box vs outside?
