You have it back wards. If you set it to HP, you turn ON the filter settings. If you set it to full that normally turns OFF the filter settings.so everyone i know says to set your comps and rear speakers to HP and not full. well the question i have is if you set it to high pass do the filter settings still work? so pretty much im asking should i or wold i get better sound leaving them on full and using the filters on my amp? i have a nine.4 and drive 2002 accord. all help is appreciated
