It will be in a trunk. I got an app from kicker that made. ported box for me but it tuned it to 40hz and it was 1.75 cuf. I want sound quality and loudness and I heard around 33 hz is good for that. So I made a custom box on the app to 33hz and the box was 2.120 cuf. But the port was only 16 sq in. and I also heard too small of a port will make bad noise. Please help I'm confused on heat to make. Also the port dimensions are 1.44in w x 15 in H x 9.14in D. Now that doesn't reach the back of the box and I thought ported boxes were supposed to snake. Idk thanks for the help.- Chris
