Help with first aero port box. Skar DDX 15

Recommended Posts

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?

Welcome to SMD. A six inch port might work with that power, but I would really use an 8. The only reason for an external port is because it won't fit in the box. Maybe @Triticum Agricolam can help.

No subs up in a trunk car, I would recommend subs / port forward sealed off or subs / port rear firing (you could try that with your current box), as for the port size 6in is on the limit for that sub in a 4 cubic feet box, it may work but likely a properly sized slot port will do better.

I’m looking to build a similar box for my zv3 15 any recommendations I want to go with an aero port as well it’s getting about 1400 rms

I suggest an 8" aero port, it will have to be long.
