I'm needing some assistance I love everything to do with car audio I always install my own equipment. At the moment I have a Sony head unit and I have 2 rockford Fosgate p2d2 wired to a coustic audio 1600 watt amp in a prefab box. I want to upgrade I am wanting 2 12 skar audio ddx subs with 2  Skar Audio RP-1500.1D amps wired at 1ohm. I don't Wana use a prefab box. I have never built a custom vented and tuned sub box. I have Ben researching on how to build a quality box. Can someone help me design a box that I can build for my ride. I have a 2002 gmc yukon denali

For that large vehicle I would go for 15s instead of 12s. Also I would probably go with one amp instead of two.
