Re: hpf settings?
The hpf has nothing to do with your subs. Hpf filters bass below chosen frequency for your door speakers. Set the hpf to 50 and your getting bass. Set the hpf to 200 and you will have zero bass. Subwoofer outputs can have lpf's. Lpf filters out bass above chosen frequency. Crazy eyes up there is saying you are asking about a problem you do not have.
