I have 2 x 12" T-4`s in a enclosure 30 x 28 x15 external dimensions, 32 mm thick all round so approx 5 cbft less sub displacement, i used 4 x 100mm pvc ports.

As you can see, first time poster, and after reading through previous related posts i`m a little concerned regarding box and port size for my sub, as posters mentioned very little room for error with this sub and frying a coil is not on my agenda whilst deciding configurations . Presently i have a box with internal measurements of 14"h x 32"d x 23"w coming in at approx 5.9 cbft. Sub will be firing upwards and ports facing horizontal. I have 2 end baffles one containg a single 9' port and the other containing 2x 6.5" ports, any help deciding which one to use would be appreciated or maybe both of them are unsuitable?. This sub will be powered by a DD Z2LV amp so juice shouldn`t be an issue. My vehicle is real happy at 40-42hz I have enclosed a pic of my previous enclosure to give you some idea of what vehicle i plan to put this new box in, thanks for your time.
