Anyone know the answer to why my Kicker 693s are freakin out when I turn them on to Full Range with my amp? I have a RSd 500.4 with a Pioneer DEH-P4800MP HU. My front door speakers run awsome on HP and even still have a little bass in them. I tried the Kickers on HP and Full but in both cases any I turn up the frequency range the speakers distort with Bass notes. And I am talkin big time bad distortion. Any ideas of whats going on would be great.
