Hello I just got a Pioneer car stereo with an Audiobahn 800 watt amp and a 12" Power Acoustik sub. I'm really confused with the settings on the Pioneer stereo. I don't know what the cut-off frequency means for the subwoofer and what the HPF setting means. I would like both highs and bass in my car. I don't want to drown my music with just bass. So how should I have the settings set up for that also. I am a nubie with car audio! Thanks for the help!
