So I'm trying to put 2 sundown x-18"s in a 2 door civic. I can get enough area if I build into the trunk but the port area is killing me. Numbers start getting crazy when tuning to 32 like recommended. I am trying to wall it but the port will have to go into the trunk and then it will be narrower and then my port area is too small.
So sundown is calling for 7 cu ft and 122 square inches per sub, but what do you think I can get away with before losing too much output? Also thinking of subs up port forward keeping the box around the window line but going all the way back in the trunk, that way I can have room for the port.
