    I'm running an aftermarket sub and subwoofer amp to replace my factory JBL sub. I have kept my factory head unit and factory amp to power the door speakers. Does anybody happen to know what the crossover/low pass filter frequency is for the factory amp? Put another way, what is the lowest frequency coming out of the door speakers?

    My aftermarket sub amp has a fixed low pass frequency of 80hz, so I'm wondering if my system is missing a frequency range that is neither provided by the door speakers nor subwoofer. It sounds like something is missing.
