No idea why you are setting any xover on the HU... you have a dsp. Use the dsp you paid that much money for, to cut, pass band everything. Run the HU open on everything, get in the dsp soft ware, and use the cut offs and slopes.....And turn everything on the head unit to off, and use the dsp you bought. Why you are adjusting freq bands, on the HU when you have a decent dsp, is..... well, .... odd. And when you are "looking for clipping" what are you playing? A song? or? And you have the "bass" on the hu all the way down? Why are you adjusting anything on the HU, if you have a full blown dsp?
EDIT- have you even gotten into the dsp software yet? Why are you using the HU to do the job of that money brick you bought? Lets start there first. Show a pic of the DSP software, not the head unit. (and set the hu all to flat, then, use the dsp you paid for)
