Passive crossovers that are bi amp capable, Amp with built in crossovers that are capable, DSP , Or head unit with active croosovers and 4 channels of amplification.
Would it work if I have 4 channels of preouts on headunit (not including sub) ram to a 4 channel running mids on rear and tweets on front channel. The amp can do high pass from 15-6000hz and low pass 50-6000 so I think that would work?
