Hey guys,
I have a JVC KD-R730BT head unit and a Hifonics BRZ1200.1D. I have my head unit LPF settings (55,85,120) with no off setting, and my amp's LPF settings (I believe 50-210) with no off setting. Anyway, I want the sub to roll off around 80-100Hz, but I have a filter coming from both sources. I've heard this can be bad. Is this true? If so, I'll just put my sub on the "rear" channel, since the only sub specific settings on the head unit are volume and LPF, and I have a volume knob from the amp.
