Let the Fun Begin
The subsonic filter is really helpful with ported boxes...not as much with sealed since sealed boxes stay controled even in the low low octaves. Usually i like to start with my lowpass set around 80 with a slope of 24db. The slope dictates how fast the frequency rolls off after the crossover slope.
for example...if you had a 80 lowpass setting with a 6 db slope, then you will be playing frequencies as high as 300hz at a higher lever then if you had the same crossover point with a 12bd, or steeper yet a 24db. The 24db slope would play 24db quieter at one octave higher then the crossover point.
hope that made some sense.

You should of got polk audio 1240's I had the kickers but they didn't last so I put two 1240's in and never looked back. Here's my not so organized system.

They are ok subs, but the sound reproduction was terrible. They would bottom out like crazy even at a lower rms than they recommended. I expected them to be a little better but they fell short. I know they arent anything special but i was let down.
Im not trying to trash what you have, just saying i found a better replacement that is a shallow mount. These polk subs are truly amazing. So smooth and accurate. I had a w6 in my old 02 f150 and these two polks are more accurate and have almost the same bass out put.
