I just replaced my xtant x1001 because I got a great deal on JL 1000/1. I will be using it to push two Diamond D6 in slot ported enclosure. Im not really exactly sure what its tuned too. It is an audio enhancer enclosure the (fb/f3) are as follows (43/33). I know that something to do with where the box is tuned to just not sure wich number is it. I have the gain set properly. I just need some help on the crossover freq. I know to have the LPF on. Im just unsure where to set the Infrasonic Filter , where to have the slope 12 or 24 or the crossover. And if anyone has suggestions on setting the q,center, boost that would be great also. I i know JL has tutorials but the hz stuff I really dont understand to much. Thanks In advance
