The mic was placed closer to the door and the port is on passenger side now if I wanted to be louder I would have theport onthe drivers side mic in the passenger side and I would shrink the net volume of the box to 4 cubes I also would tune to 65 hertz and burp at 78 hertz which is my 3/4 wave however originally though I just wanted a loud daily driver which is why I'm tuned to 40 hertzandthe port is on the passenger side also I had access to 4 powerbass 5000s but onlychose to. Run 2 because everybody was 2 chicken to run in my class however if db drag starts coming around I will be extremely happy so I can have some competition and will actually have a reason to bring the civic out the caddy however will stay like it is.
