So it just occurred to me why my clipping light has been flashing more frequently with my new Alpine CDA-117. I have the HPF on the deck set to 100 Hz. That doesn't affect the subs at all, only the speakers. And the LPF on my AQ 1200D doesnt work no matter which way you turn it from 20-200Hz. So basically, for the past month my subs have been trying to play every frequency. I dont know what to do now..
