Tuning Amplifier
I have a Logic CP620 amp on a MTX Blue Thunder 12. I have been tweaking the settings a number of different ways because there are times when the bass really hits i hear a noise like someone is thumping the cone. i know that this is probably an over excursion of the cone. any ideas on eliminating this?

If its not that then it is likely the amp clipping, which is really bad also.

37Hz - 150Hz is the frequency response on the sub. My head unit has a front image enhancing feature on it that cuts all the lows to the rears and all the highs to the front. There are three settings for it. 100 hz, 160 hz, and 250 hz. I had it set to 160 hz plus my amp was set to 77.5 hz. So my if you do the math that was higher than the max frequency response for my sub. I put the F.I.E on 100 hz and turned the crossover down to 17.5 hz and it sounds good.
