Re: Enclosure Design Help
A single 8 inch sub in a sealed box isn't going to have tremendous output to begin with, but it shouldn't be almost inaudable in a small car like that...
Have you tried turning the box around or moving it to different areas of the trunk? It might do better loading off of a wall and firing backwards.
Otherwise, a ported enclosure can give you at least a 6 - 10DB gain down low, if designed correctly. With cabin gain factored in, it would be significantly louder below 50hz.
The port back, sub up design would be my choice or port up sub back.
