Okay so i am determined to get low. i listen to only slowed / re-bassed music no desire for anything mainstream and could care less about anything above 40 hz. if i can play it great if not oh well. the range id like to be able to play is 15-30ish hz I just like it low. I need some help getting there. I understand i need to tune low but how low should i tune? and port area is another concern i have. typically 12-18 port area per cube is optimal but when your tuning to 20ish hz its impractical. should i sacrifice port area ? if so to what extent before it becomes a whistle box.

I have 2 dss ethos and about 2k rms

Your gonna mount the amp the the sub box? Ive heard thats not a good idea, being that the sub box is gonna vibrate like crazy from the bass, specially since u want nothing but lows. Would u really want the amp mounted to that, shaking up all the electrical hardware and stuff in the amp? Might not matter and still be fine, but i wouldnt risk it.

well if i want to keep everything in the hatch thats the only way space wise ive got an amp rack on top of it with rubber boots at the mounting feet.

Ok well this is about the best you'll be able to do with the space you have available. I tried to give you as much port area as possible while keeping your port lengths within reason. It sounds like you'll only be giving these about half their rated power, which will be fine for this box. However, if you ever add more power this box may get a little small (and weak for 4000 watts).
