going to do a 30 wide by 18 deep by 16.5 high double baffled box build. (3.5 cubes tuned to 27 hertz) sub and port forward. I've been talking to RAM and he says 2 3" aeros would fit but nothing bigger. so would i be better off doing a slot port and doing a 45 degree turn at the back cuz idk if i can make a curve. also i have some triangular metal pieces of support in my trunk that would be about 7 inches in front of the box and would be cover approximately the bottom 1/3 of the slot port (7 inches in front of it). so which would i be better off doing? 2 3" aeros or the slot port. and will the metal bracing that close effect it? and ik the circle port creates less air / sound pockets/ build up, but will i still get as much air movement in the car with both types of ports?
