Lok my EQ and Lanzer crossover have there own "level knobs"
I first checked for clipping at the headunit found it at 32. I left out the EQ so my setup went like this,
Headunit rca's to lanzer crossover then rca runs to bass amp and 4ch amp. I left headunit at 32 then treated the crossover as the headunit and checked for clipping the same way as headunit was done but this time turning the level knobs on crossover up to look for distortion but nothing. I got stumped and just left out the crossover.
