    I just installed a Lanzar 1200D amp in my car yesterday and am wondering what I should set these settings to?

    Its powering a 10inch infinity kappa in a crappy bandpass box.

    I dont know much about the settings and what they do so anything you guys can tell me will help me out.

    Thanks.

    Lowpass - ~80Hz usually. Play with it a little and see what sound best.
    Subsonic - details on the box would help but I'd start at ~30Hz. Problem with a bandpass is (besides obvious ones everyone will want to mention) the box is pretty effective at masking any stress noises made by the drive so its hard to tell if you're pushing it too hard.

    I don't think bandpass requires a subsonic filter, since one side is sealed and should protect the driver. As far as low-pass, that's up to your ears and to your front speakers. If you have very strong midbass response from your fronts, 80Hz might be fine. But, I'll bet you'll enjoy 100 or 125Hz more.
