I am attempting to build a ported downfiring box for a 79 chevy truck. I have bucket seats and am going to make the box run down the middle of the seats. My Max space is 48" long by 17" Wide by 10" tall. I am planning on using an Alphasonik PSW815 which has a 8" mounting depth. I would like to go more towards SPL than SQ. Anyone have any ideas for placement of the port and dimensoins? Here is a rough idea of how the box should look mius the port.
