Hello, i have pioneer head unit connected with hertz dsk 165.3 2 way speaker system with amp , what high pass filter value have to set at head unit to work whole system correctly?
You need to re-phrase the question. Are you trying to use active bi-amplification via outboard amplifiers or do you just want the recommended frequency to set the HU or the amp? Start at 40-50Hz. What amp? Are you running a subwoofer?
